Online Tech Info
Thermal
cutouts and temperature/current cutouts with electrical
self-hold switch off after reaching the set temperature
or current level. The switch is then held open by
a parallel switched heating resistance (PTC) - the
cutout will not automatically reset while voltage
is applied. It will reset when voltage is removed
(i.e. the appliance concerned is disconnected) and
the cutout has cooled down.
