Thermal miniature circuit breaker, pluggable in screw-type fuse terminal block UK 6-FSI/C and spring-cage fuse terminal block ST 4-FSI/C
Thermal circuit breakers provide optimum protection against overload for your consumers in power distribution systems. When the circuit breaker trips, the integrated switch function enables immediate reactivation. Unlike a fuse, the circuit breaker does not need to be replaced. The higher the overload, the faster the thermal device circuit breaker trips.More information
Thermal device circuit breakers are normally tripped via a bimetal strip. In the event of a fault, the bimetal heats up and disconnects the circuit.
As a rule, 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 pluggable versions.
Typical areas of application for thermal device circuit breakers are sensors and actuators in systems.
These include motors, heating elements and fans, and devices with high starting current.
Thermal device circuit breakers have a maximum voltage range of 250 V AC or 65 V DC.
