A snap-action thermostat/thermal protector with the highest contact ratings of any of our controls. Suitable for use on 120/240 VAC loads. Available with variety of bi-metallic elements to enhance performance characteristics.


  •     Conductive bimetal construction; the bimetallic element carries the circuit current for maximum current sensitivity under short circuit conditions.
  •     Snap action device, quick make/quick break switching action.
  •     Temperature differential between opening and closing may vary from 20° C to 70° C depending upon the no-load calibration temperature.
  •     Preset calibration temperature; not adjustable in the field.
  •     Case electrically alive; insulating sleeving is available.

Contact Ratings

    20 amps/120volts AC resistive
    10 amps/240volts AC resistive

Calibration Temperature Range

    Available with nominal calibration temperatures from 70° C to 150° C.
