Klixon Phenolic Motor Protectors are equipped with a bimetallic or trimetallic snap acting disc, on which the contacts are mounted, and through which the current flows.

ConstructionThe basic element in the on-winding motor thermostatis the Klixon snap-acting disc. The electrical circouit consists of the pin, insulated from the caseby the glass-to-metal seal,connected to the stationary contact through the disc to the case.

This protector is designed to protect 3‑phase refrigeration and air conditioning compressor motors from excessive winding temperature; however, applications may be made to any WE Wound 3‑phase motors where environmental conditions require a hermetic seal.

The 35HM is designed to reduce installation costs by replacing pilot control systems with a simple, economical, compact device.

The 34HM is designed to reduce installation costs by replacing pilot control systems with a simple, economical, compact device.

The Klixon‑31HM, 32HM, and 33HM on‑winding motor protectors are 3‑phase line‑break, automatic‑reset devices wired in series with each phase at the neutral point.

The 18HM sealed AC motor protector features a robust integrated sealed structure, offering comprehensive protection against motor burnout and overloading.
