Westinghouse Electric 966467-H Overload Relay Heater

The Westinghouse Electric 966467-H Overload Relay Heater is a plug-in thermal heater element (AC93) designed to provide motor overload protection in Westinghouse overload relay assemblies and motor starters. It generates heat proportional to motor current, allowing the associated overload relay to trip during sustained overload or locked-rotor conditions to protect electric motors. Commonly installed in motor control centers, magnetic starters, industrial machinery, conveyors, pumps, compressors, fans, and HVAC equipment, this replacement heater element works with compatible Westinghouse overload relays and motor starters. It carries Part Number 15-827, Alternate Number 966467-H, and is designated AC93 with a plug-in mounting design for straightforward installation and replacement.
