Definite Purpose Contactors & Starters CR453A Series Contactors CR454A Series Starters Caution: Before installing in a nuclear application, determine that the product is intended for such use. Warning: Disconnect power before installing or servicing. Description GE’s CR453A magnetic contactors provide a 2- or 3-pole device for use in air conditioning units or other general purpose applications. These instructions give information Ratings – Full Voltage, Non-Reversing Frame Size about ratings, installation, accessories and wiring, overload relay may be added if needed. Factory assembled starters CR453AB CR454A include overload relay.

Connect the bell set or resistancemeasuring instrument across the relay terminals. Depress and release the reset arm to ensure the relay is reset. In this condition there should be continuity between the terminals. In the tripped condition, the circuit between the terminals should be open indicating the contacts are operating CR453AB, AC, AD normally. Remove the bell set or resistance measuring apparatus, rewire the relay terminals and reset the relay for normal operation.
