GE CR123H186B Thermal Unit 16 A

The GE CR123H186B is a thermal protection unit rated for a full-load current of 16.00 A. It serves industrial electrical controls and automation circuits that require reliable overload sensing. Maintenance engineers and panel builders use it as a direct replacement in compatible motor-starter assemblies.

Sustained load behaviour

Under continuous operation the unit monitors the 16 A circuit and trips when the temperature rise exceeds the calibrated threshold. It is designed to carry the rated current indefinitely without nuisance tripping while still responding to genuine overload conditions. The transparent housing allows visual inspection of the internal element during routine checks.

16 A full-load rating

The single specification that determines suitability is the 16.00 A full-load current rating; the starter or contactor must match this value exactly. Compatibility is confirmed against the listed Grainger and manufacturer part numbers such as CR101H and CR101Y series. Buyers whose application demands a different current rating cannot use this unit.

Questions about this item

How much heat or power does the CR123H186B thermal unit generate when running continuously at 16 A?

The unit is rated for a full load current of 16 A and operates as a protective thermal element within compatible motor starters; it does not produce significant heat itself but responds to overload conditions in the circuit it protects.

What existing starter or contactor is required for this GE thermal unit to function?

It is designed for use with GE CR101H, CR101H1, CR101H11, CR101Y, CR101Y11 or Grainger 3HYJ6 through 3HYK2 starters; the unit installs directly into those specific overload relay housings.

Will this 16 A thermal unit work with older GE CR101 series starters I already have installed?

Yes, it is compatible with multiple CR101H and CR101Y variants listed in the specifications, allowing direct replacement in those legacy motor starter assemblies.
