Control Transformer Selection Procedure

The following steps will assure that the secondary voltage delivered by your transformer will be either 85%, 90% or 95% of the nameplate sec-ondary voltage under maximum inrush conditions, at rated input volt-age. A typical selection example based on these steps follows.

Step 1

Calculate the total SEALED (steady

state) VA load of your control circuit.

This is done by adding the continu-ous VA requirements of the maxi-mum number of components that will be energized at any given time, including non-inductive as well as inductive components. For Sealed VA data see

Page 12-6

.

Step 2

Calculate the PEAK INRUSH VA of

your control circuit.

First, analyze the sequence of operation of all components. Then add together the inrush VA ratings of the components that will be energized simulta-neously. Next, determine the peak — or maximum simultaneous — inrush VA load that the transformer will “see.” The VA requirements for indi-cating lights, timers and other non-inductive components which do not have an inrush VA also should be included since they will present a load to the transformer at the time of maximum inrush.

Step 3

Calculate the TRANSFORMER

SELECTION INRUSH VA.

Use the fol-lowing formula:

NOTE:

Transformer Selection Inrush VA also can be determined by add-ing the inrush VA and sealed VA arithmetically, but this usually results in an oversized transformer.

Step 4

Determine the correct transformer

NAMEPLATE VA RATING.

Refer to the Inrush/Regulation Data table: If the line supply to the transformer is fairly stable (does not vary more than 5%), use the 90% secondary voltage column — the 90% column is most commonly used. If the line supply voltage varies up to 10%, use the 95% voltage regulation column. To determine the correct VA trans-former rating, go down the column until you arrive at the inrush VA rat-ing closest to, but not less than, the Transformer Selection Inrush VA calculated in Step 3. The left hand column of the table will give the corresponding transformer NAME-PLATE VA RATING.

Inrush/Regulation Data

NOTE:

When evaluating supply-line stability, remember that supply-line voltage drop frequently is associated with motor-starting inrush current. When motors and motor controls are connected to a common feeder, the controls will experience a momentary voltage dip when the motor starts. This reduces the con-trol transformer voltage supplied to the motor starting contactor and may cause the contactor to chatter or drop out.

Selection Example

Steps 1 and 2

By following Steps 1 and 2 described in column one at left, analysis of the control circuits shows the following sealed VA and inrush VA data:

Step 3

Following Step 3 in column one at left, the Transformer Selection Inrush VA is calculated at 1773 VA.

Steps 4 and 5

Following Steps 3 and 4 at left, the Inrush/Regulation Data Chart is then consulted to find the correction name-plate VA size of the transformer. Under the 90% Secondary Voltage column, we find that a 320 VA transformer will deliver 2224 VA, amply covering circuit demands of 1880 Inrush VA. Checking this selection against the requirements of 311 VA sealed, we confirm that a 320 VA transformer will be sufficient.

Description

These control transformer kits pro-vide a convenient on-the-job addi-tion of control transformers to the following NEMA 1, 3R, 4/4X and 12 enclosed starters. Adding or chang-ing these kits does not affect the UL listing in most instances.

For Non-combination Starters

These kits may be used for trans-former voltage conversion on Free-dom NEMA, IEC and Advanced Design NEMA (Advantage) starters furnished from the factory with con-trol transformers installed. Non-combination starters with CPTs fac-tory installed are Class ECN07,

ECA07, ECE07 and ECE11. These kits may also be installed in oversize enclosures that have been designed to accept transformers.

Combination Starters

Most combination starters have space for standard size (and 100 VA extra capacity) control power trans-formers. The panels are pre-drilled for mounting.

UL/CSA

UL listed — File Number E10156, Guide XPTQ.

Applications

Cutler-Hammer MachineTool and Control Transformers provide stepped-down voltages to machine tool control devices, enabling con-trol circuits to be isolated from all power and lighting circuits.

This allows the use of grounded or ungrounded circuits that are inde-pendent of the power or lighting grounds; greater safety is afforded the operator. The control trans-former line is particularly adaptable on applications where compact con-struction is demanded. Electrical performance equals or exceeds ANSI/NEMA standards.

Type MTA Transformers

■

■

100% tested to verify product quality.

■

Electrical performance equals or exceeds requirements of ANSI/NEMA ST-1.

■

Type MTC

Type MTC Control Transformers are similar to Type MTA except MTC provide increased regulation.

Features

■

Designed specifically for loads requiring extremely good regula-tion — 10% to 200% better regula-tion than Type MTA.

■


■

Electrical performance exceeds requirements of ANSI/NEMA ST-1.

■

100% tested; each unit must pass rigid tests for turns ratio, insulation, continuity, and over potential.

Type APThe Type AP Control Transformers feature an encapsulated core and coil which provides a totally enclosed, non-ventilated construc-tion. Smaller than open core and coil type units, connections are made with the convenient screw type ter-minal board. For ease of installation, two types of mounting are provided. Select a design with the base plate arranged for bottom mounting or for side/wall mounting.

Features■ UL recognized.

■ Resin encapsulated.

■ Convenient screw-type terminal board.

■ Bottom or side/wall mounting designs.

■ Performance meets/exceeds ANSI/NEMA ST-1 requirements.

■ Regulation exceeds ANSI/NEMA requirements for all ratings.

■ 115°C winding rise.
