Thermal circuit breakers

Small but powerful – these device circuit breakers are as narrow as flat-type fuses, but can be restarted.

Our thermal device circuit breakers provide optimum protection for inductive loads against overload in power distribution systems. The integrated switching function of the circuit breakers enables them to be switched on again immediately, thereby minimizing downtimes in your system.

 

Your advantages

  • Suitable for all flat-type fuse inserts, thanks to standardized plug-in contacts
  • Shortened downtimes, thanks to immediate restart after tripping
  • Space-saving installation, thanks to narrow design

 

Function and design

Thermal circuit breakers are normally triggered via a bimetal strip. In the event of an error, the bimetal heats up and disconnects the circuit.

As a rule: the higher the overload, the more quickly the thermal circuit breaker trips.

The devices can be switched on again at any time. Thermal circuit breakers are available as plug-in versions.

 

Areas of application

Typical areas of application for thermal circuit breakers are sensors and actuators in systems.

These include, for example, motors, heating elements and fans, and devices with a high starting current.

The maximum voltage ranges for thermal circuit breakers are 250 V AC or 65 V DC.
