Thermal circuit breakers - function and design


Thermal circuit breakers are normally triggered via a bimetallic strip. This means that in the event of an error, the bimetal heats up and disconnects the circuit.

As a rule: the higher the overload, the faster the thermal circuit breaker is triggered. The devices can be switched on again at any time.

Thermal circuit breakers are available as plug-in versions.
