GE CR123H739A 6.41 A Thermal Unit

GE CR123H739A Thermal Unit

The GE CR123H739A is a thermal overload unit rated for a full-load current of 6.41 A. It is designed for industrial electrical control and automation panels. Maintenance engineers and panel builders use it to protect motor circuits from sustained overcurrent conditions.

Compatible with Series CR123H73 and listed

This unit fits directly into the CR123H73 series and matches manufacturer references including CR101H, CR101H1, CR101H11, CR101Y, CR101Y1 and CR101Y11. It also crosses to Grainger part numbers 3HYJ6 through 3HYK2. Selecting the correct match frees the installer from trial-and-error fitting during panel assembly or retrofit.

Rated 6.41 A full-load current for motor protection

The 6.41 A rating defines the continuous current the unit carries before thermal tripping occurs. It comfortably handles motors and loads operating at or below this value. Circuits drawing higher sustained current will exceed the trip threshold, so a different rating must be chosen for those applications.
