Versatile, multipurpose creep action thermostats/thermal protectors for temperature control and sensing applications.  Available with gold-diffused contacts for exceptionally low contact resistance in critical low-voltage/low current circuits.


  • Conductive bimetal construction; the bimetallic element carries the circuit current.
  • No built-in differential between the opening and closing temperature.
  • Case electrically alive; insulating sleeving is available.
  • Preset calibration temperature; not adjustable in the field.
  • Available to open circuit on rise of temperature (normally closed), Model C; or close circuit on rise of temperature (normally open), Model CR.
  • Available with gold diffused, fine silver contacts for use in low voltage/low current applications.
  • -C and -CH versions without gold diffused contacts.
  • -CH and CH versions for use 130°C to 200°C.

Contact Ratings

  • 6 amps 120 VAC resistive
  • 5 amps 120 VAC inductive
  • 6 amps 12 VDC resistive
  • 4 amps 24 VDC resistive
