GE CR123H486A Thermal Unit 4.22A

This GE thermal unit is an industrial electrical control accessory rated for a full load current of 4.22 A. It is designed for integration with compatible motor starter or contactor assemblies. The transparent housing allows visual inspection of internal components during operation or maintenance checks.

Sustained load behaviour at 4.22 A

Under continuous full load current of 4.22 A, the unit manages thermal dissipation to protect the connected control circuit. It responds to prolonged overcurrent conditions rather than momentary spikes, maintaining circuit integrity during extended equipment cycles. The device operates passively within the starter assembly without active cooling requirements.

Build quality and mounting implications

The transparent construction provides immediate visibility of contact status or trip indication without disassembly. Compatibility with listed Grainger part numbers and manufacturer model numbers ensures direct replacement fit in existing control panels. Standard industrial terminal spacing allows straightforward wiring into legacy or new motor control centres.

Questions about this item

How much heat does the GE CR123H486A thermal unit generate when running continuously at 4.22 A?

The thermal unit is rated for a full-load current of 4.22 A and is designed to operate within compatible motor starter enclosures; sustained operation at this rating will produce heat consistent with standard overload protection devices.

Which motor starter models must I already own for the GE CR123H486A to fit and function?

The thermal unit is compatible with manufacturer model numbers CR101H, CR101H1, CR101H11, CR101Y, CR101Y1 and CR101Y11, so one of those starters is required for proper installation.

Will the GE CR123H486A thermal unit work with older Grainger 3HYJ and 3HYK series starters I may still have in service?

Yes, the unit is listed as compatible with Grainger part numbers 3HYJ6, 3HYJ7, 3HYJ8, 3HYJ9, 3HYK1 and 3HYK2, allowing direct replacement in those older starter assemblies.
