GE CR123H575A Thermal Unit

The GE CR123H575A is a thermal protection unit rated for a full load current of 5.00 A. It is designed for industrial electrical control and automation panels. This accessory suits engineers and maintenance teams who need reliable overload protection for compatible motor starters.

Transparent housing and starter compatibility

The unit features a transparent housing that allows visual inspection of the internal mechanism. It is compatible with Grainger part numbers 3HYJ6 and 3HYJ9, as well as manufacturer part numbers CR101H and CR101Y. This matching ensures correct fitment within existing starter assemblies.

Replaces worn thermal units in specific starters

This thermal unit serves as a direct replacement for failed or aged units in CR101H and CR101Y series starters. The upgrade is worth it when the original element has tripped repeatedly or shows signs of heat damage. It is not for builders needing different current ratings or incompatible starter models.

Questions about this item

What full-load current does the CR123H575A thermal unit handle in practice?

The unit is rated for a full-load current of 5.00 A, so it will trip at that level to protect the circuit.

Which physical mounting pattern or footprint does the CR123H575A require?

It is designed to match the CR101H and CR101Y form factor, fitting the same panel cut-out and screw spacing as those models.

What is the correct installation step that is often missed when fitting the CR123H575A?

Insert the unit into the compatible CR101H or CR101Y starter base and seat it firmly until the latch engages; a loose fit will prevent proper thermal sensing.
