Bulletin 1410 — Motor Winding Heater

Bulletin 1410 Motor Winding Heater is intended for use with 3-phase AC motors to guard against damage caused by condensation build-up on motor windings, which can occur in high-humidity environments during motor off times. This device is not intended to be used to dry out damp motors.

Bulletin 1410 Motor Winding Heater is designed for used with 3-phase AC squirrel-cage motors controlled by automatic full-voltage starters. For applications involving reduced-voltage starters, multi-speed starters, synchronous motors, or the used of power factor correction capacitors, consult your local Rockwell Automation sales office or Allen-Bradley distributor.
