Protection discrimination

ContentsUsing the tablesTwo circuit breakers offer total discrimination when the corresponding box in the discrimination table is shaded or contains the letter T.When discrimination is partial for the combination, the corresponding box indicates the maximum value of the fault current for which discrimination is provided. For fault currents above this value, the two circuit breakers trip simultaneously.

Protection discriminationD

�814

Protection discrimination is an essential element that must be taken into account starting at the design stage of a low voltage installation to ensure the highest level of availability for users.Discrimination is important in all installations for the comfort of users, however it is fundamental in installations requiring a high level of service continuity, e.g. industrial manufacturing processes. Industrial installations without discrimination run a series of risks of varying importance including:

production deadline overrunsinterruption in manufacturing, entailing:production or finished-product lossesrisk of damage to production machines in continuous processesrestarting of machines, one by one, following a general power outage shutdown of vital safety equipment such as lubrification pumps, smoke fans, etc.

What is discrimination?Discrimination, also called selectivity, is the coordination of automatic protection devices in such a manner that a fault appearing at a given point in a network is cleared by the protection device installed immediately upstream of the fault, and by that device alone.

total discriminationDiscrimination is said to be total if, for all fault current values, from overloads up to the non-resistive short-circuit current, circuit breaker D2 opens and D1 remains closed.

partial discrimination Discrimination is partial if the above condition is not respected up to the full short-circuit current, but only to a lesser value termed the selectivity limit current (Is).

no discriminationIn the event of a fault, both circuit breakers D1 and D2 open.

Total discrimination as standard with the new Masterpact NT/NW circuit breakersThanks to their highly innovative design and the exeptional performance of their control units, the new Masterpact NT and NW circuit breakers offer total discrimination with downstream Compact NSX devices up to 630 A as standard (1).

Natural discrimination with Compact NSX circuit breakersDue to the Roto-active breaking technique employed by the Compact NSX, the combined use of Merlin Gerin circuit breakers provides an exceptional level of protection discrimination.This is the result of the implementation and optimisation of three different techniques:

current discriminationtime discriminationenergy discrimination.

Overload protection: current discriminationDiscrimination is ensured if the ratio between setting thresholds is greater than 1.6(for distribution circuit breakers).Low short-circuit protection: current discrimination

Tripping of the upstream device is slightly delayed to ensure that the downstream device trips first.Discrimination is ensured if the ratio between the short-circuit thresholds is greater than 1.5.High short-circuit protection: time discrimination

This protection system combines the exceptional current limiting capacity of the Compact NS and the advantages of reflex tripping, sensitive to the energy dissipated in the device by the short-circuit. In the event of a high short-circuit detected by two circuit breakers, the downstream device limits it sharply. The energy dissipated in the upstream device is not sufficient to trip it, i.e. discrimination is total for all short-circuit currents.Discrimination is ensured if the ratio between the circuit breaker ratings is greater than 2.

(1) Except for the L1 performance level on Masterpact NT and subject to the discrimination rules on page 7.

How to use the discrimination tablesfor discrimination between 2 distribution circuit breakers

Combinations providing full discrimination are indicated by the symbol T. If discrimination is partial, the table indicates the maximum fault current value for which discrimination is ensured. For fault currents above this value, the 2 circuit breakers trip simultaneously.

Protection discrimination with fuses

PrincipleSchneider Electric offers a coordinated protection systemIn an electrical installation, fuse protection devices are never used alone and must always be integrated in a system comprising circuit breakers. Coordination is required between:

upstream and downstream fusesupstream circuit breakers and downstream fusesupstream fuses and downstream circuit breakers.

bbb

Fuse upstream / Fuse downstreamDiscrimination is ensured whenTotal energy of downstream fuse (Etav) < Pre-arcing energy of upstream fuse (Epam)Note: If Etav is higher than 80 % of Epam, the upstream fuse may be derated.

gG fuse-link upstream / gG fuse-link downstreamStandard IEC 60�69-�-� indicates limit values for pre-arcing and total energies for operation of gG and gM fuse-links, where the operating current is approximately �0 In.

gG fuse-link upstream / aM fuse-link downstreamThe I = f (t) curve for an aM fuse-link is steeper. aM fuse-links are just as fast as gG fuse-links for short-circuit currents, but slower for low overloads.That is why the discrimination ratio between gG and aM fuse-links is approximately �.5 to 4.

RuleExamination of discrimination at the critical points on the LT (long time) and ST (short time) curves results in a discrimination table.Analysis of the LT critical point indicates whether discrimination between the protection devices is possible or not.Analysis of the ST (or Icw) critical point indicates whether the discrimination limit is greater than or equal to the ST (or Icw) value.

Note:the LT critical point is the most restrictivefor circuit breakers with a Icw value that is high and/or equal to Icu, the ST critical point is

almost never a problem, i.e. discrimination is total.

bb

Upstream circuit breaker with non-delayed ST (short time) protection and/or current-limiting functionTo make sure the ST critical point is OK, it is necessary to compare:

the energy curves of the protection devicesthe non-tripping curves of the upstream circuit breaker and the fusing curves of the

downstream fuse, and to run tests for the critical values.

overload zone - coordination between Masterpact and the thermal relayMasterpact offers an EIT long-time setting that is totally coordinated with the curves of the thermal relay. Discrimination is ensured as long as the setting ratio is greater than �.6.

short-circuit zone - coordination between Masterpact and the aM fuse-linkUnder short-circuit conditions > �0 In, the I = f (t) characteristic of an aM fuse-link is very similar to that of a gG fuse-link with the same rating.

Given the above and using the EIT long-time setting, Masterpact offers the same discrimination ratios for both gG and aM fuse-links downstream. This ratio is very similar to that for gG fuse-links installed upstream of aM fuse-links.

Note: if there are motor feeders protected by aM fuse-links and distribution lines protected by gG fuse-links downstream of a Masterpact circuit breaker, selection of HVF long-time curves is the means to ensure identical discrimination for both types of circuit.See pages �6 to �4 for the discrimination tables.

l2t ON settingTo significantly limit the stresses exerted on the installation (cables installed on trays, power supplied by an engine generator set, etc.), it may be necessary to set the ST protection function to a low value.The I�t ON function, a constant-energy tripping curve, maintains the level of discrimination performance and facilitates total discrimination.

Cascading

What is cascading?Cascading is the use of the current limiting capacity of circuit breakers at a given point to permit installation of lower-rated and therefore lower-cost circuit breakers downstream.The upstream Compact circuit breakers acts as a barrier against short-circuit currents. In this way, downstream circuit breakers with lower breaking capacities than the prospective short-circuit (at their point of installation) operate under their normal breaking conditions.Since the current is limited throughout the circuit controlled by the limiting circuit breaker, cascading applies to all switchgear downstream. It is not restricted to two consecutive devices.

General use of cascadingWith cascading, the devices can be installed in different switchboards. Thus, in general, cascading refers to any combination of circuit breakers where a circuit breaker with a breaking capacity less than the prospective Isc at its point of installation can be used. Of course, the breaking capacity of the upstream circuit breaker must be greater than or equal to the prospective short-circuit current at its point of installation.The combination of two circuit breakers in cascading configuration is covered by the following standards:

IEC 60947-� (construction)NF C �5-�00, § 4�4.�.� (installation).

Coordination between circuit breakersThe use of a protective device possessing a breaking capacity less than the prospective short-circuit current at its installation point is permitted as long as another device is installed upstream with at least the necessary breaking capacity.In this case, the characteristics of the two devices must be coordinated in such a way that the energy let through by the upstream device is not more than that which can be withstood by the downstream device and the cables protected by these devices without damage.Cascading can only be checked by laboratory tests and the possible combinations can be specified only by the circuit breaker manufacturer.

Cascading and protection discriminationIn cascading configurations, due to the Roto-active breaking technique, discrimination is maintained and , in some cases, even enhanced. Consult the enhanced discrimination tables on page �� to page �44 for data on discrimination limits

Cascading tablesMerlin Gerin cascading tables are:

drawn up on the basis of calculations (comparison between the energy limited by the upstream device and the maximum permissible thermal stress for the downstream device)

verified experimentally in accordance with IEC standard 60947-2.For distribution systems with ��0/�40 V, 400/4�5 V and 440 V between phases,the tables of the following pages indicate cascading possibilities between upstream Compact and downstream Multi 9 and Compact circuit breakers as well as between upstream Masterpact and downstream Compact circuit breakers.

220/240 V network downstream from a 380/415 V networkFor 1P + N or 2P circuit breakers connected between the phase and neutral on a 380/415 V network, with a TT or TNS neutral system, consult the 220/240 V cascading table to determinate cascading possibilities between upstream and downstream circuit breakers, for C60 upstream and consult the 380/415 V cascading table for iDPN.

For 1P + N or 2P circuit breakers connected to one phase of a 380/415 V network used together with the neutral to supply a single-phase circuit, consult the cascading tables for 380/415 V networks to determine the cascading possibilities between upstream and downstream circuit breakers.

Example of three level cascadingConsider three circuit breakers A, B and C connected in series. The criteria for cascading are fulfilled in the following two cases:

the upstream device A is coordinated for cascading with both devices B and C (even if the cascading criteria are not fulfilled between B and C). It is simply necessary to check that the combinations A + B and A + C have the required breaking capacity

each pair of successive devices is coordinated, i.e. A with B and B with C (even if the cascading criteria are not fulfilled between A and C). It is simply necessary to check that the combinations A + B and B + C have the required breaking capacity.The upstream breaker A is a NSX250L (breaking capacity 150 kA) for a prospective lsc of 80 kA across its output terminals. A NSX100B (breaking capacity 25 kA) can be used for circuit breaker B for a prospective lsc of 40 kA across its output terminals, since the "reinforced" breaking capacity provided by cascading with the upstream NSX250L is 50 kA. A C60H (breaking capacity 15 kA) can be used for circuit breaker C for a prospective lsc of 24 kA across its output terminals since the "reinforced" breaking capacity provided by cascading with the upstream NSX250L is 25 kA. Note that the "reinforced" breaking capacity of the C60H with the NSX100B upstream is only 20 kA, but:

A + B = 50 kAA + C = 25 kA.

Cascading and enhanced discrimination

With traditional circuit breakers, cascading between two devices generally results in the look of discrimination.With Compact circuit breakers, the discrimination characteristics in the tables remain applicable and are in some cases even enhanced. Protection discrimination is ensured for short-circuit currents greater than the rated breaking capacity of the circuit breaker and even, in some cases, for its enhanced breaking capacity. In the later case, protection discrimination is total, i.e. only the downstream device trips for any and all possible faults at its point in the installation.ExampleConsider a combination between:

a Compact NSX�50H with trip unit TM�50Da Compact NSX�00F with trip unit TM�5D.

The discrimination tables indicate total discrimination. Protection discrimination is therefore ensured up to the breaking capacity of the NSX�00F, i.e. 36 kA.The cascading tables indicate an enhanced breaking capacity of 70 kA.The enhanced discrimination tables indicate that in a cascading configuration, discrimination is ensured up to 70 kA, i.e. for any and all possible faults at that point in the installation.

Enhanced discrimination tables - 380/415 VFor each combination of two circuit breakers, the tables indicate the:

selectivity limit enhanced by cascading (in kA)

downstream device breaking capacity enhanced by cascading (in kA)

15 / 25

In a table, a box containing two equal values indicates that discrimination is provided up to the reinforced breaking capacity of the downstream device.These tables apply only to cases with combined discrimination and cascading between two devices. For all other cases, refer to the normal cascading and discrimination tables.

Technical principleEnhanced discrimination is the result of the exclusive Compact NSX Roto-active breaking technique which operates as follows:

due to the short-circuit current (electrodynamic forces), the contacts in both devices simultaneously separate. The result is major limitation of the short-circuit current

the dissipated energy provokes the reflex tripping of the downstream device, but is insufficient to trip the upstream device.

Motor protection discrimination

ContentsUsing the tablesTwo circuit breakers offer total discrimination when the corresponding box in the discrimination table is shaded or contains the letter T.When discrimination is partial for the combination, the corresponding box indicates the maximum value of the fault current for which discrimination is provided. For fault currents above this value, the two circuit breakers trip simultaneously.

Protection of motor circuitsCircuit breaker/contactor coordination

A circuit supplying a motor may include one, two, three or four switchgear or controlgear devices fulfilling one or more functions.When a number of devices are used, they must be coordinated to ensure optimum operation of the motor.Protection of a motor circuit involves a number of parameters that depend on:

the application (type of machine driven, operating safety, starting frequency, etc.)the level of service continuity imposed by the load or the applicationthe applicable standards to ensure protection of life and property.

The necessary electrical functions are of very different natures:protection (motor-dedicated for overloads)control (generally with high endurance levels)isolation.

Protection functionsDisconnection functions:

Isolate a motor circuit prior to maintenance operations.Short-circuit protection:Protect the starter and the cables against major overcurrents (> �0 In).Control:Start and stop the motor, and, if applicable:

gradual accelerationspeed control.

Overload protection:Protect the starter and the cables against minor overcurrents (< �0 In).Additional specific protection:

limitative fault protection (while the motor is running)preventive fault protection (monitoring of motor insulation with motor off).

Overloads (I < 10 In).An overload may be caused by:

an electrical problem, for instance on the mains (loss of a phase, voltage outside tolerances, etc.)

a mechanical problem, for instance excessive torque due to abnormally high demands by the process or motor damage (bearing vibrations, etc.)A further consequence of these two origins is excessively long starting.Impedant short-circuit (10 < I < 50 In)Deterioration of motor-winding insulation is the primary cause.Short-circuit (I > 50 In)This type of fault is relatively rare. A possible cause may be a connection error during maintenance.Overload protectionThermal relays provide protection against this type of fault. They may be:

integrated in the short-circuit protective deviceseparate.

Short-circuit protectionThis type of protection is provided by a circuit breaker.Protection against insulation faultsThis type of protection may be provided by:

a residual current device (RCD)an insulation monitoring device (IMD).

Applicable standardsA circuit supplying a motor must comply with the general rules set out in IEC standard 60947-4-� and in particular with those concerning contactors, motor starters and their protection as stipulated in IEC 60947-4-�, notably:

coordination of the components of the motor circuittrip class for thermal relayscontactor utilisation categoriescoordination of insulation.

Coordination of the components of the motor circuitTwo types of coordinationThe standard defines tests at different current levels. The purpose of these tests is to place the switchgear and controlgear in extreme conditions. Depending on the state of the components following the tests, the standard defines two types of coordination:

type 1: Deterioration of the contactor and the relay is acceptable under two conditions:

no danger to operating personnelno danger to any components other than the contactor and the relaytype 2:

Only minor welding of the contactor or starter contacts is permissible and the contacts must be easily separated.

following type-� coordination tests, the switchgear and controlgear functions must be fully operational.Which type of coordination is needed?Selection of a type of coordination depends on the operating conditions encountered.The goal is to achieve the best balance between the user’s needs and the cost of the installation.

type 1: qualified maintenance service

low cost of switchgear and controlgearcontinuity of service is not imperative or may be ensured by simply replacing the

faulty motor drawertype 2:continuity of service is imperativelimited maintenance servicespecifications stipulating type 2.

The different test currents"Ic", "r" and "Iq" test currentsTo qualify for type-� coordination, the standard requires three fault-current tests to check that the switchgear and controlgear operates correctly under overload and short-circuit conditions."Ic" current (overload I < 10 In)The thermal relay provides protection against this type of fault, up to the Ic value (a function of Im or Isd) defined by the manufacturer.IEC standard 60947-4-� stipulates two tests that must be carried out to guarantee coordination between the thermal relay and the short-circuit protective device:

at 0.75 Ic, only the thermal relay reactsat �.�5 Ic, the short-circuit protective device reacts.

Following the tests at 0.75 and �.�5 Ic, the trip characteristics of the thermal relay must be unchanged. Type-� coordination thus enhances continuity of service. The contactor may be closed automatically following clearing of the faul."r" current (Impedant short-circuit �0 < I < 50 In)The primary cause of this type of fault is the deterioration of insulation. IEC standard 60947-4-1 defines an intermediate short-circuit current “r”. This test current is used to check that the protective device provides protection against impedant short-circuits.There must be no modification in the original characteristics of the contactor and the thermal relay following the test.The circuit breaker must trip in y �0 ms for a fault current u �5 In.

“Iq” current (short-circuit I > 50 In)This type of fault is relatively rare. A possible cause may be a connection error during maintenance.Short-circuit protection is provided by devices that open quickly.IEC standard 60947-4-1 defines the “Iq” current as generally u 50 kA.The “Iq” current is used to check the coordination of the switchgear and controlgear installed on a motor supply circuit.Following this test under extreme conditions, all the coordinated switchgear and controlgear must remain operational.

AC3 utilisation categoryThis category covers asynchronous squirrel-cage motors that are switched off during running. This is the most common situation (85 % of all cases).The control device establishes the starting current and interrupts the rated current at a voltage equal to approximately one-sixth of the rated value.Current interruption is carried out with no difficulty.

AC4 utilisation categoryThis category covers asynchronous squirrel-cage or slip-ring motors capable of operating under regenerative-braking or inching (jogging) conditions.The control device establishes the starting current and is capable of interrupting the starting current at a voltage that may be equal to that of the mains.Such difficult conditions require oversizing of the control and protective devices with respect to category AC�.

Protection of motor circuitsUsing the circuit breaker/contactor

Subtransient phenomena related to direct on-line starting of asynchronous motorsSubtransient phenomena occurring when starting squirrel-cage motors:A squirrel-cage motor draws a high inrush current during starting. This current is related to the combined influence of two parameters:

the high inductance of the copper stator windingthe magnetisation of the iron core of the stator.

In motor: current drawn by the motor at full rated load (in A rms)Id: current drawn by the motor during starting (in A ms)Id’’: subtransient current generated by the motor when it is energised. This very short subtransient phenomenon is expressed as k x Id x r �

(in A peak).td: motor starting time, from 0.5 to �0 seconds depending on the application.td’’: duration of the subtransient current, from 0.0�0 to 0.0�5 seconds when the

motor is energised.Irm: magnetic setting of the circuit breakers.

bb

Typical upper and lower limits for these subtransient currents:These values, not covered by standards, also depend on the type of motor technology used:

mordinary motors Id’’ = � Id to �.� Id (in A peak)bhigh-efficiency motors Id’’ = 2.2 Id to 2.5 Id (in A peak).bvariation of Id’’ as a function of Id:b

Type of motor d Id’’(in A rms) (in A peak)

Ordinary motor 5.8 to 8.6 In motor Id’’ = � Id = ��.5 In (A peak)to Id’’ = �.� Id = �8 In (A peak)

High-efficiency motor 5.8 to 8.6 In motor Id’’ = �.� Id = ��.5 In (A peak)to Id’’ = �.5 Id = ��.5 In (A peak)

Example: Upon energisation, a high-efficiency motor with an Id of 7.5 In produces a subtransient current with a value between (depending on its characteritics):

minimum = 16.5 In (in A peak)maximum = 18.8 In (in A peak).

Protection of motor circuitsUsing the circuit breaker/contactor coordination tables

Subtransient currents and protection settings:as illustrated in the above table, subtransient currents can be very high.If they approach their upper limits, they can trip short-cicuit protection devices

(nuisance tripping)circuit breakers are rated to provide optimum short-circuit protection for motor

starters (type � coordination with thermal relay and contactor)combinations made up of circuit breakers and contactors and thermal relays are

designed to allow starting of motors generating high subtransient currents (up to �9 In motor peak)

the tripping of short-circuit protective devices when starting with a combination listed in the coordination tables means:

the limits of certain devices may be reachedthe use of the starter under type � coordination conditions on the given motor may

lead to premature wear of one of the components of the combination.In event of such a problem, the ratings of the starter and the associated protective devices must be redesigned.

Using the coordination tables for circuit breaker and contactors:

ordinary motor:The starter components can be selected directly from the coordination tables, whatever the values of the starting current (Id from 5.8 to 8.6 In) and the subtransient current

high-efficiency motors with Id y 7.5 In:The starter components can be selected directly from the coordination tables, whatever the values of the starting current and the subtransient current

high-efficiency motors with Id > 7.5 In:When circuit breakers are used for motor currents in the neighbourhood of their rated current, they are set to provide minimum short-circuit protection at 19 In motor (A peak).There are two possibilities:

the subtransient starting current is known (indicated by the motor manufacturer) and is less than 19 In motor (A peak).In this case, the starter components can be selected directly from the coordination tables, whatever the value of the starting current (for Id > 7.5 In).Example: for a ��0 kW �80/4�5 V �-phase motor, the selected components are:NSX�50-MA��0/LC�-F��5/LR9-F5�7�.

the subtransient starting current is unknown or greater than �9 In motor (A peak).In this case, the value used for the motor power in the coordination tables should be increased by �0 % to satisfy optimum starting and coordination conditions.Example: for a ��0 kW �80/4�5 V �-phase motor, the selected components are those for a motor power of ��0 + �0 % = �� kW: NSX400 Micrologic 4.�M/LC�-F�65/LR9-F5�7�

Starting class and thermal relaysThe data in the tables chapter 555E�050 "Installation recommandations" corresponds to “normal” motor starting times. The associated thermal relays are either class �0 or �0 A (tripping time < �0 s).

for motors with long starting times, the class �0 or �0 A thermal relays must be replaced with class �0 thermal relays as indicated in the correspondence table opposite (for type � and type � coordination)

long starting times requiring a class �0 relay:apply a derating coefficient (K = 0.8) to the circuit breaker and the contactor

Example: e.g.NS100H MA 100 for 80 A maximum. LC1F115 for 92 A maximum.these tables may also be used for standard thermal protection using current

transformers. The required thermal relays are:

LR�-D��05 (0.6� to � A) for class �0LR�-D�505 (0.6� to � A) for class �0 with terminal block LA7-D�064.

The current transformer ratings must be 5 VA per phase. The other characteristics are identical to those described below.

Example: An INFp160 can receive BS fuse-links in sizes A2, A3 or A4, which correspond to the following ratings:

A2 size:� to �� A for gG fuse-links��M�5 to ��M6� for gM fuse-linksA3 size:�5 to 6� A for gG fuse-links6�M80 to 6�M�00 for gM fuse-linksA4 size:80 to �00 A for gG fuse-links�00M��5 to �00M�00 for gM fuse-links.

The tables on page �86 to page �90 directly indicate the correct selection of fuse-links and Fupact switches depending on the distribution-circuit rating and the motor rating (for direct-on-line starting).

�� Protection of motor feedersA motor feeder is generally made up of:

a control contactora thermal relay for overload protectiona short-circuit protection devicean disconnection device capable of interrupting load currents.

The Fupact switch-disconnector-fuse is the ideal device for the last two points in the list. What is more, Fupact is totally compatible with the IEC 60�04 machine directive.Additional specific protection:

limitative fault protection (while the motor is running)preventive fault protection (monitoring of motor insulation with motor off).

Fupact characteristicsThe local emergency-off switch must have the AC�� characteristic for the rated motor current.Motor starting characteristics are the following:

peak current: 8 to �0 Induration of peak current: �0 to �0 msstarting current Id: 4 to 8 Instarting time td: � to 4 seconds.

Short-circuit protection of motors is ensured by aM or gM (�) fuse-links that are sized to take into account the above characteristics.Fupact offers a wide range of fuse utilisations, whatever the applicable reference standard.(1) A gM fuse-link is in fact simply a derated gG fuse-link.

Coordination of devices on the motor feederthermal protection of the:motorconductorsswitch fuse

is ensured by the thermal relay on the contactor.overload (or short-circuit) protection of the:motorconductorsswitchthermal relayis ensured by the fuse.

To ensure a high level of operational quality, it is important to ensure coordination of the devices on the motor feeder in compliance with standard IEC 60947-4. The equipment manufacturers provide type-� and type-� coordination tables between fuse-links, contactors and thermal relays.

IEC 947.3UTE VDE BS CEI UNE

Functions and positions of LV switchesThe switch is therefore essentially a control device, (generally manual, possibly electrical on opening - termed a free tripping switch) capable of breaking and closing a normal service circuit. It does not use any electricity to remain open or closed (� stable positions). For safety reasons, in the majority of cases is suitable for isolation.It must always be used in association with a device which protects against overloads and short-circuits.6 applications have thus been identified:

coupling and insolating switch in a power switchboardinsulating switch in an industrial switchboard and automation cabinetsinsulating switch in a modular switchboardinsulating switch in proximity unitsinsulating switch in small commercial distribution unitsautomation unit switch.

bbbbbb

Suitable for isolationSwitch-disconnectorIsolation permits a circuit or a device to be disconnected from the rest of the electrical installation, in order to guarantee the safety of those who have to achieve repairs or maintenance.Normally, all circuits in an electrical installation must be capable of being isolated. In practice, to ensure optimal continuity of service, an isolating device is installed at the start of every circuit distribution.Certain switches allow this function to be achieved in addition to their circuit control function. Therefore a switch-disconnector must display the symbol (illustrated opposite), visibly on the front face of the installed device.Isolating functionInstallation standards stipulate the requirements which must be respected in order for a device to carry out its isolating function.It must:

be with equipped with omnipolar isolation, that is to say that the live conductors, including the neutral (with the exception of the PEN conductor which must never be isolated) must be isolated simultaneously

be lockable in the “open” position so as to prevent any risk of unvolontary reclosing this is imperative for industrial devices

conform to a standard which guarantees its suitability for isolation It must also meet overvoltage withstand requirements. However, if the isolation is

explicitly recognized by a manufacturing standard, for example IEC 60947-1/3 for industrial switch-disconnectors, a device which complies with this isolation standard is judged to comply fully with the conditions required by installation standards.The manufacturing standard guarantees its use for isolation suitability for the user.

The IEC standards 60947-� (1) and 60669-� (2) thus define the principal values which are given below.Utilization categoryDepending on the rated operating current and the A or B mechanical endurance, standards define the utilization categories shown in the table below.Example:A switch with a rating of ��5 A, from the AC�� category must be able to:

make a �0 In (��50 A) current with a cos j of 0.�5break a 8 In (�000 A) current with a cos j of 0.�5.

Its other characteristics are:to withstand a 12 In - 1 s short-circuit current, which defines the Icw = 1500 A r.m.s.

Choosing a Schneider Electric switch

The switch must be chosen according to:b the characteristics of the network on which it is installed,b the location and the application,b coordination with the upstream protection devices (in particular overload and short-circuit).

Choice criteriaNetwork characteristicsNominal voltage, nominal frequency and nominal current are determined in the same way as for a circuit-breaker:

nominal voltage = nominal voltage of the networkfrequency = network frequencynominal current = rated current of a value immediately higher than the

downstream load current. Note that the rated current is defined for a given ambient temperature and that a derating may have to be taken into account.Location and applicationThis determines the type and characteristics or main functions that the switch must possess. There are � function levels (see table opposite):

basic functions, virtually common to all switch types:isolation, control, padlocking, safety.additional characteristic functionsdirect formulation of the needs of the user and of the switch environment, i.e.:industrial type performanceneed for emergency stoppinglsc leveltype of interlockingtype of controlutilization categorymounting system.specific functionslinked to operation and to installation requirements, i.e.:earth leakage protectionmotor mechanismsremote opening (“emergency stop” function)withdrawability.

The following table enables choice of switch according to requirements.choice table

Comparison of the application table K (see page �07) and the switch technical data table M (see page �09) lets you specify which switch range should be used.CoordinationAll switches must be protected by an overcurrent protection device placed upstream.The "additional technical information" tables below give the SCPD (circuit-breaker or fuse) guaranteeing proper coordination with switches in event of a downstream short-circuit, according to the electrodynamic withstand or the short-circuit making capacity of the device.

Inrush currentsWhen LV/LV transformers are switched on, very high inrush currents are produced which must be taken into account when choosing overcurrent protection devices.The peak value of the first current wave often reaches 10 to 15 times the rated rms current of the transformer and may reach values of �0 to �5 times the rated current even for transformers rated less than 50 kVA.

�945 Selecting the protection

Merlin Gerin has conducted an extensive test programme to optimise the protection of LV/LV transformers.The Compact and Masterpact circuit breakers detailed in the following tables offer the following advantages:

protection of the transformer in the event of abnormal overloadsno nuisance tripping when the primary winding is energisedunimpaired electrical endurance of the circuit breaker.

The transformers used for the tests are standard. The values in the tables have been calculated for a crest factor of �5. These tables indicate the circuit breaker and trip unit to be used depending on:

the primary supply voltage (��0 V or 400 V)the type of transformer (single-phase or three-phase).

They correspond to the most frequent case in which the primary is wound externally (1).The type of circuit breaker to be used (i.e. N, H or L) depends on the breaking capacity required at the point of installation.

Capacitor-bank protection.

Protection of capacitorsIt is necessary to take into account:

permissible variations in the fundamental voltage and in harmonic contentThe increase in the current rating for the protection device may reach �0 %.

variations due to capacitor tolerances.The increase in the current rating for the protection device may reach �5 % (but only 5 % for Rectiphase capacitors).Given the above, the generally required correction factor ranges from �.6 to �.For Rectiphase capacitor banks, an optimised factor of only �.4 may be used for standard banks.

Coordination tables between circuit breaker and Canalis electrical busbar trunking

When chosing a circuit breaker to protect a busbar trunking system, it is necessary to take into account:

the usual rules concerning the circuit breaker current settings:Ib y Ir y Inc where:Ib = maximum load currentIr = circuit breaker current settingInc = current rating of the busbar trunking

the electrodynamic withstand of the busbar trunking: the peak current Î limited by the circuit breaker must be less than the electrodynamic withstand capacity (or rated peak current) of the busbar trunking.Coordination tablesThe tables for coordinating Merlin Gerin.

Traditional circuit breaker selection methodThe circuit breaker used to protect a distribution circuit is chosen according to two fundamental criteria:

the maximum load current Ib flowing in the supply circuitthe prospective short-circuit current Isc at a point where the circuit breaker is to be

installed.The circuit breaker is choosen such that:

In circuit breaker u Ibbreaking capacity of the circuit breaker u Isc.

Coordination tables between circuit breaker and Canalis electrical busbar trunking

ExampleConsider two 6�0 kVA/400 V transformer (Usc 4 %) supplying a main LV switchboard for which the prospective short-circuit current on the busbars is 44 kA.From the switchboard, a �0-metre long Canalis KVA6� transmission electrical busbar trunking system (6�0 A) supplies a Canalis KSA6� trunking system (6�0A) for distribution with high-density tap-offs. A tap-off on the KSA6� trunking supplies a Canalis KSA�6 trunking system.The short-circuit level are respectively:

44 kA downstream of circuit-breaker CB� and at the upstream connection of the KVA6� trunking

Coordination tables between circuit breaker and Canalis electrical busbar trunkingEnhanced discrimination through cascading

IntroductionThe use of current-limiting circuit breakers makes it possible to implement coordination techniques. This improves circuit breaker performance in terms of breaking capacity and continuity of service.Coordination techniques are described and recognised by the following standards:

product standards IEC 60947-� and 60947-� installation standards IEC 60�64, NF C�5-�00, etc

CascadingThe use of a current-limiting circuit breaker upstream to reinforce the breaking capacity of a downstream circuit breaker.

Coordination tables between circuit breaker and Canalis electrical busbar trunkingEnhanced discrimination through cascadingDiscriminationIn the event of an electrical fault on one outgoing circuit, discrimination is the ability of the electrical installation to maintain the continuity of electrical power supplied to the other circuits not concerned by the fault.As a general rule, cascading and discrimination techniques are applied independently.Schneider Electric has developed an exclusive system to conciliate cascading and discrimination.This system ensures discrimination up to the reinforced breaking capacity of the association of circuit breakers CB� and CB�.

Coordination tables between circuit breaker and Canalis electrical busbar trunkingEnhanced discrimination through cascadingCascading, reinforced discrimination and reinforced protection of busbar trunking systems (BTS)This technique is the direct application of cascading and discrimination techniques to the protection of busbar trunking systems.For various upstream circuit breakers and upstream busbar trunking systems, the tables below give directly:

the level of short-circuit protection of the busbar trunkingthe downstream circuit breaker and associated busbar trunkingthe cascading breaking capacity of the downstream circuit breakerthe level of reinforced discrimination of the upstream and downstream circuit

breakersthe level of reinforced protection of the downstream busbar trunking.
