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

Please consult our Sales Engineers for suggested contact ratings when applied to DC type loads.

Calibration Temperature Range

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