These Snap Action Thermostats operate as a high limit, single operation (non-resettable) type control.  Ultra fast thermal response times due to the unique positon of the bimetal element.  The ceramic case allows them to operate at temperatures up to 260°C.  As single operation thermostates they perform like a thermal fuse with the reliability of a 100% tested bimetallic thermal control.


  • Snap action devices; quick make/quick break switching action.
  • Single Operation type devices. Reset temperature is less than -35°C. This prevents the thermostat from resetting under normal operating conditions.
  • Unique positioning of the bi-metallic element allows for excellent heat transfer for improved reaction time.
  • Available with exposed bi-metallic elements for even faster thermal response.
  • Ceramic case isolates devices from the electrical circuit and is suitable for use in high temperature applications.
  • Can be mounted directly on a heated surface.
  • Preset calibration temperature, not adjustable in the field.
  • Opposite end termination allows for flexibility of installation.
  • Factory installed lead wires or terminals available – Consult Factory.
