A family of snap-action thermal protectors in an electrically isolated plastic case.  Offers both overcharge and short-circuit protection in rechargeable battery packs.  Low internal resistance for maximum protection and minimal effect on battery pack performance.  Designed to meet tighter space requirements of smaller battery packs.


  • Conductive bimetal construction; the bimetallic element carries the circuit current for maximum current sensitivity under short circuit conditions.
  • Snap action device, quick make/quick break switching action.
  • Temperature differential between opening and closing may vary from 5°C to 35°C depending upon the no load calibration temperature.
  • Case is electrically isolated from the circuit.
  • Preset calibration temperature; not adjustable in the field.
  • Equipped with gold diffused, fine silver contacts for use on low voltage/low current applications.

Contact Ratings

  • 10 amps 12 VDC
  • 5 amps 24 VDC

Calibration Range

  • Available with nominal calibration temperatures from 50°C to 100°C.
  • Reset temperature greater than 35°C
