— Manual motor starters CR123 heaters for CR101 manual motor starters

Overload heater units for CR101H, CR101Y All CR123H heaters are packaged as single units.

The table below gives a proper size heater to trip the switch on approximately 125% motor current. Listed values are for motors with 1.15–1.25 service factor. For motors with 1.0 service factor continuously, multiply full-load current of motor by 0.9 and use this value to select heater. Contact nearest ABB Representative for recommendation on heaters to be used with definite-purpose motors. If motor full-load amperes falls between two ratings, select heater for the highest of those two. For 1.35 service factor motors, multiply full-load current of motor by 1.15 and use this value to select heater(s).
