GE CR123H188A Thermal Unit
The GE CR123H188A is a thermal unit rated for a full-load current of 1.63 A. It serves as a protective component for motor starters and compatible control gear in industrial electrical panels. The transparent housing allows visual inspection of the internal mechanism. It is designed for maintenance engineers and panel builders who need a direct replacement for existing overload relays.
Current rating and compatibility
The unit operates at a fixed 1.63 A full-load current and cannot be adjusted for other motor sizes. It is listed as compatible with Grainger part numbers 3HYJ6 and 3HYJ9 and manufacturer model numbers CR101H and CR101Y. Buyers who need a different current setting or a unit for a non-listed starter series will not be served by this specific part number.
Verification before ordering
Confirm that the existing starter or overload block matches the CR101H or CR101Y model designation exactly. Cross-reference the 1.63 A rating against the motor nameplate full-load amperage to ensure correct protection. The product ships directly from the distributor for orders of 75 or more, so single-unit buyers should verify lead times with their supplier.

Questions about this item
Which GE thermal unit model matches my 1.63 A motor load?
The CR123H188A is rated for a full-load current of 1.63 A and is compatible with Grainger parts 3HYJ6 and 3HYJ9, so select this unit when your motor nameplate shows that exact amperage.
How does the 1.63 A rating protect my motor in daily use?
The 1.63 A thermal unit trips when sustained current exceeds that value, preventing overheating while allowing normal start-up surges on motors matched to this rating.
What starter series does the CR123H188A fit and what does that limit?
It fits GE CR101H and CR101Y starters, limiting use to those specific starter models for proper overload protection coordination.
