Thermal device circuit breakers protect individual pieces of equipment against overload
Our thermal device circuit breakers provide optimum protection against overload for inductive loads in power distribution systems. The integrated switching function of the device circuit breakers enables immediate switch-on again and minimizes 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 slim design
Function and design
Thermal device circuit breakers are conventionally tripped by means of a bimetallic strip. In the event of an error, the bimetal heats up and disconnects the circuit.
The following applies: the higher the overload, the faster the thermal device circuit breaker trips.
The devices can be switched on again at any time. Thermal device circuit breakers are available as plug-in designs.
Areas of application
Typical areas of application for thermal device circuit breakers include system-based sensors and actuators.
These include: motors, heating elements and fans, and devices with a high starting current.
The voltage ranges of thermal device circuit breakers are a maximum of 250 V AC or 65 V DC.
