GE CR123H055A Thermal Unit

The GE CR123H055A is a thermal unit rated for a full load current of 0.48 A. It serves as a protective component for compatible motor starters and contactors. Maintenance technicians and panel builders select this accessory to match specific overload requirements in industrial control panels.

Sustained load behaviour

Under continuous operation the unit monitors current at the rated 0.48 A level and trips when thermal limits are exceeded. This response protects downstream equipment from prolonged overcurrent conditions rather than momentary peaks. The transparent housing allows visual confirmation of status during extended duty cycles.

Deciding specification

The critical value is the 0.48 A full load current rating which must match the motor nameplate data exactly. Compatibility is limited to the listed Series CR101 and Grainger part numbers 3HYJ6 through 3HYK2. Buyers needing a different current rating or a non-CR101 mounting format cannot use this unit.
