SynTemp® – Temperature Monitoring

SynTemp® S01/S02 or S06/S08

Series S01 or S06 thermal cut-offs are moulded, permanently operating bimetal release switches which interrupt the current flow once the nominal temperature has been reached (normally closed contact). Opening/ closing combination also possible. 

Attributes

Permanent operation with immediate reaction once the switching temperature has been reached is ensured due to the unique free-moving and self-aligning construction of the bimetal disc in the thermal cut-off.The thermal cut-offs are available as a single component and in a twin or triplet version.

Further advantages due to the bimetal perforated discs:

  • excellent long-term stability
  • improved space utilisation
  • high mechanical strength
  • excellent long-term stability
Application

The S01 and S06 thermal cut-offs are used in electric motors and transformers.
