GE CR123H377A Thermal Unit

The GE CR123H377A Thermal Unit is an industrial electrical control component rated for a full load current of 3.27 A. It is designed for use with compatible motor starters and overload relays in automation systems. The transparent housing allows visual inspection of the internal mechanism.

Suited for maintenance on Series CR123H37 starters

This unit suits technicians replacing thermal protection on existing GE Series CR123H37 motor starters or the listed Grainger part numbers. It is not for buyers who need a different current rating or a unit compatible with other starter series.

Full load current 3.27 A

The decisive specification is the 3.27 A full load current rating. The thermal unit must match the motor nameplate current to provide correct overload protection. Verify the required ampere rating before ordering.
