A creep-action thermostat/thermal protector.  Shunted type bimetal design allows for higher contact ratings.  Equipped with gold diffused contacts for use in low voltage/low current applications.


  • Shunted bimetal construction; the bimetallic element does not carry the circuit current.
  • Creep action device; slow make/slow break switching action.
  • Frictional differential between opening and closing varies from 2° C to 10° C from the opening temperature.
  • Case electrically alive; insulating sleeving is available.
  • Preset calibration temperature; not adjustable in the field.
  • Equipped with gold diffused, fine silver contacts for use in low voltage/low current applications

Contact Ratings

  • 8 amps 120 VAC resistive
  • 6 amps 120 VAC inductive

Calibration Range

  • Available with nominal calibration temperatures from 5°C to 150°C.
