Functions and characteristics

Mechanical interlocking of two or three devices is used to create a remote-operated source-changeover system. A basic mechanical interlocking system enhances the reliability of system operation.

Interlocking of two Compact NSX100 to 630 devices using a base plateA base plate designed for two Compact circuit breakers can be installed horizontally or vertically on a mounting rail. Interlocking is carried out on the base plate by a mechanism located behind the breakers. Access to the circuit breaker controls and trip units is conserved. Circuit breakers must be fixed or plug-in versions, with or without earth-leakage protection or measurement modules. The base plate and the circuit breakers are supplied separately.

b Base plate for Compact NSX100 to 250 devicesThis base plate is intended for two Compact NSX100 to 250 devices.

b Base plate for Compact NSX400 to 630 devicesThis base plate is intended for two Compact NSX400 to 630 devices. It may also be used, without any modifications, to interlock a fixed Compact NSX100 to 250 with a Compact NSX400 or 630 device.An adapter kit is required for plug-in versions of the Compact NSX100 to 250 devices.Compact NSX100 to 250 devices, in both fixed and plug-in versions, may be equipped with spreaders.

ps Interlocking of two Compact NS630b to 1600 or two Masterpact NT and NW devices using connecting rodsThe two devices must be mounted one above the other (either 2 fixed or 2 withdrawable/drawout devices).Combinations are possible between Compact NS630b to NS1600 devices and between Masterpact NT and Masterpact NW devices.InstallationThis function requires:

b an adaptation fixture on the right side of each circuit breaker or switch-disconnector

b a set of connecting rods with no-slip adjustments.The adaptation fixtures, connecting rods and circuit breakers or switch-disconnectors are supplied separately, ready for assembly by the customer.The maximum vertical distance between the fixing planes is 900 mm.

ps Interlocking of two Compact NS630b to 1600 or two Masterpact NT/NW or up to three Masterpact NW devices using cablesFor cable interlocking, the circuit breakers may be mounted one above the other or side-by-side.The interlocked devices may be fixed or drawout, three-pole or four-pole, and have different ratings and sizes.

Interlocking between two devices (Compact NS630b to 1600 or Masterpact NT and NW)This function requires:

b an adaptation fixture on the right side of each device b a set of cables with no-slip adjustments.

The maximum distance between the fixing planes (vertical or horizontal) is 2000 mm.

Interlocking between three devices (Masterpact NW only)This function requires:

b a specific adaptation fixture for each type of interlocking, installed on the right side of each device

b two or three sets of cables with no-slip adjustments.The maximum distance between the fixing planes (vertical or horizontal) is 1000 mm.InstallationThe adaptation fixtures, sets of cables and circuit breakers or switch-disconnectors are supplied separately, ready for assembly by the customer.Installation conditions for cable interlocking systems:

b cable length: 2.5 m b radius of curvature: 100 mm b maximum number of curves: 3.
