Economical snap-action thermal protectors designed for a cost effective solution for protection in motor, transformer, and lighting applications. Available with various bimetallic elements to match the current sensitivity of the device to the application.


  • Snap-action design, quick break/quick make switching action.
  • Compact design with a high switching contact rating.
  • Conductive bimetal construction: The bimetal carries the circuit current for maximum sensitivity under short circuit conditions.
  • Drawn metal case has a low profile design.
  • Case is electrically alive; insulating sleeving is available.
  • Available in a low and high bimetal resistance for optimum current and temperature sensitivity.
  • Suitable for vacuum impregnation processes.
