    Description

    The 3HM hermetic overload protectors are new generation product designed to meet the demands of tomorrow’s compressors. The 3HM family of motor protectors can be applied to air conditioning compressors ranging from 1 to 2½ HP. They may also be used in commercial motors which must function in high-pressure corrosive environments. Its low profile allows ease of installation, while the overall design provides resistance to mechanical shock.

    Constructions

    The basic element in the hermetic motor protector series is the Klixon snap-acting disc. An integral series heater allows close control of ON times, and longer cycle rates when stalled rotor condition exists. Glass sealed header is resistant welded to the steel case to provide a hermetic seal. Optional wire leads, sleeve and terminal connector can be provided.
