GE CR123H090A Thermal Unit 0.78 A video accessory

Thermal unit for GE controls

The GE CR123H090A thermal unit is an industrial electrical control accessory rated for a full load current of 0.78 A. It is designed to provide overload protection in compatible motor starter assemblies. This new component arrives in a transparent housing and serves as a direct replacement part for existing installations.

Maintenance teams and panel builders

This unit suits technicians servicing GE CR101H or CR101Y starters where the 0.78 A trip rating matches the motor nameplate. Buyers protecting motors with a different full-load current must select a thermal unit with the correct ampere rating. The part is not a standalone controller and cannot function without the appropriate starter base.

0.78 A full load current rating

The decisive specification is the 0.78 A full load current, which must match the motor's rated current for proper thermal protection. Confirm this value against the motor nameplate or the original unit markings before ordering. Compatibility is confirmed for Grainger part numbers 3HYJ6 and 3HYJ9 alongside the manufacturer part numbers listed.
