Relevant applications:


2-pole safety limiter with automatic reset



  • Fast reaction time
  • Choice of configurations for function
  • Optimized reading of temperature in immersion applications
  • Non self resetting  limiter
  • Guarantee of safety operation:  fail-safe capillary
  • Factory pre-set fixed temperature
  • Possibility for changeover contact on double pole version



Capillary :  The liquid within the capillary is transformed to vapour with an abnormal increase in temperature.  The increase in volume acts on a mechanism to open electrical contacts.  The limiter is manually resettable.  In case of damage to the capillary the fail-safe limiter operates automatically.

Bimetal : A snap action bimetal opens electrical contacts with an abnormal increase in temperature.
