A creep action thermal protector in an exceptionally small package.  Low internal resistance and gold diffused contacts makes this device suitable for use in low voltage/low current applications.


  • Conductive bimetal construction; the bimetallic element carries the circuit current.
  • Creep action device; slow make/slow break switching action.
  • No built-in differential between the opening and closing 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.
  • Available to open circuit on rise of temperature (normally closed), Model N; or close circuit on rise of temperature (normally open), Model NR.

Contact Ratings

  • 2.6 amps 120 VAC inductive
  • 8 amps 12 VDC resistive
  • 4 amps 24 VDC resistive

Calibration Range

  • Model N 30°C to 130°C
  • Model NR 30°C to 120°C
