Syntemp S01 and S06

Description

Series S01 and 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. 

Properties

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:
-high spring resistance with small spring travel
-improved space utilisation

-very high mechanical strength

-excellent long-term stability

Application

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