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). Closing combination also possible (S02 or S08).
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.
