Supco OV34 Universal Motor Overload Protector 14-15.5 LRA 1/10-1/3 HP

The Supco OV34 is a universal replacement motor overload protector designed for compressors and motors in a wide range of HVAC-R and appliance applications. Part of Supco's trusted OV Series, it serves as a direct replacement overload for systems rated between 14.0 and 15.5 locked rotor amps (LRA).

The OV34 uses a built-in temperature-activated bimetal disc that automatically opens and closes the protector's contacts in response to excessive heat. When a compressor, motor, or crankcase heater generates unsafe heat levels, the disc opens the circuit to prevent serious equipment damage or motor burnout. Once cooled, the contacts reset automatically.
