Description

3-phase capillary safety limiter with manual reset.

 

Features

  • Factory pre-set fixed temperature
  • Failsafe safety capillary
  • Independent non self resetting safety
  • Double pole single throw version (DPST)
  • Multiple mounting, electrical connection and reset knob configurations

Operation

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.
