A creep-action thermal protector with a shunted type bimetal design.  This lowers the current sensitivity and slows the cycle rate of the device.


  • 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.
  • Preset calibration temperature; not adjustable in the field.
  • Case electrically alive; insulating sleeving is available.
  • Equipped with gold diffused, fine silver contacts for use in low voltage/low current applications.

Contact Ratings

  • 2.5 amps/120 volts AC inductive

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

Calibration Range

  • Available with nominal calibration temperatures from 30°C to 150°C
