GE CR123H245A Thermal Unit

The GE CR123H245A Thermal Unit is an industrial electrical control accessory rated for a full load current of 2.13 A. It serves as a thermal protection component for compatible motor starters and contactors in automation systems. Maintenance technicians and panel builders working with specified GE CR101 series devices will find this unit matches their replacement requirements.

Replaces worn thermal units in CR101H

This thermal unit replaces original equipment in Grainger part numbers 3HYJ6 through 3HYK2 and manufacturer models CR101H, CR101H1, CR101H11, CR101Y, CR101Y1, CR101Y11. The jump is worth it when an existing unit has tripped repeatedly or shows signs of thermal fatigue. Buyers needing a different current rating or a non-GE starter compatibility cannot use this part.

Direct drop-in for listed compatible models

Installation consists of removing the old thermal unit and seating this CR123H245A into the same slot on the starter body. No wiring changes are required for the listed compatible models. What usually goes wrong is selecting the wrong ampere rating or forcing the unit into an unlisted starter series, which prevents proper seating and thermal contact.

Questions about this item

Does the thermal unit mount with the hook-and-loop closure shown in the 1.800 3" spec?

Yes, the unit uses a hook-and-loop closure for mounting in harsh environments.

How is the CR123H245A installed into a CR101H or CR101Y overload relay?

Insert the thermal unit into the relay base until it seats firmly; the common mistake is not pushing it fully home so the contacts do not engage.

When should the 2.13 A thermal unit be replaced?

Replace it after an overload trip or if the relay fails to reset, as the internal element is single-use.
