Westinghouse 15-827 Overload Relay Heater 966467-H AC93

Description:

The Westinghouse 15-827 Overload Relay Heater 966467-H (AC93) is a thermal overload heater element designed for use in Westinghouse overload relay assemblies and motor starter systems. This heater element provides motor overload protection by generating heat proportional to motor current, allowing the associated overload relay to trip when sustained overload conditions occur. It is commonly installed in industrial motor control equipment, magnetic starters, and motor protection systems where dependable thermal overload protection is required.

Applications:

The Westinghouse 15-827 AC93 heater element is commonly used in motor control centers, magnetic motor starters, industrial machinery, conveyor systems, pumps, compressors, fans, and HVAC equipment. It works with compatible thermal overload relays to help protect electric motors from overheating and damage caused by excessive current draw or locked-rotor conditions.
