Selection of Control Circuit Transformers The standard primary/secondary voltages for control circuit transformers are indicated in . To order, select the desired device with the appropriate transformer Form designation. Then convert the previously selected voltage code (V●●) to reflect the desired primary/ secondary voltage for the transformer. The secondary voltage should equal the previously selected coil voltage of the device. Example: You have selected 8536SDG1V02S. V02S means that you need a coil voltage of 120-60/ 110-50 wired for separate control. You would like to add FormFF4T , with transformer voltages of 480 V primary, 120 V secondary, and solid-state overload relay protection with selectable Class 10/20 trip class—Form H30 . (The Form designations needed are FF4 , H30 , and T .) The new and complete Class, Type, voltage code, and Form number will be: Class Type Voltage Code Form [17] 8536 SDG1 V81 FF4H30T
