A creep-action thermostat/thermal protector with a higher resistive-bimetallic element for increased current sensitivity.  Available with gold diffused contacts for use in low voltage/low current applications.


  • Creep action device; slow make/slow break switching action.
  • No built-in differential between the opening and closing temperature.
  • Conductive bimetal construction; the bimetallic element carries the circuit current for maximum sensitivity under short circuit conditions.
  • Preset calibration temperature; not adjustable in the field.
  • Case electrically alive; insulating sleeving is available.
  • Available with gold diffused, fine silver contacts for use in low voltage/low current applications.
  • Available to open circuit on rise of temperature (normally closed), Model K; or close circuit on rise of temperature (normally open), Model KR.
  • -K and -KH versions without gold diffused contacts.
  • -KH versions for use from 80°C to 200°C.

Contact Ratings

  • 4 amps/120 volts AC resistive
  • 4 amps/120 volts AC inductive

Calibration Range

  • Available with nominal calibration temperatures from 5°C to 200°C
