GE CR123H446A Thermal Unit

The GE CR123H446A is a thermal protection accessory rated for a full load current of 3.88 A. It serves industrial electrical control and automation systems where precise overload monitoring is required. Transparent housing allows visual inspection of internal status. This unit suits maintenance engineers and panel builders integrating GE CR101 series starters.

Replaces legacy CR101H and CR101Y thermal units

Direct compatibility covers Grainger part numbers 3HYJ6 through 3HYK2 and manufacturer part numbers CR101H, CR101H1, CR101H11, CR101Y, CR101Y1, CR101Y11. The jump is worth it when existing thermal units show trip inconsistency or physical degradation. It restores calibrated protection without rewiring the starter enclosure.

Handles 3.88 A continuous load

Designed for motor circuits operating at the stated current rating, it provides reliable overload detection within the specified range. It runs out when system current exceeds the fixed 3.88 A threshold or when application demands adjustable trip classes. Buyers needing variable current settings or higher ampacity must select a different thermal unit class.
