8.9.2 TCB thermal circuit breaker option
General
The TCB thermal circuit breaker protects the braking resistor from constant overload
and protects in case of a short circuit in the cable or the braking resistor.
The setting range of the thermal circuit breaker has to be selected in such a way that it
corresponds to the tripping current I
F
of the braking resistor.
The switch reacts to the following events:
• Thermal overload via current monitoring device.
• Short circuit.
In the event of a fault, the thermal circuit breaker switches off the braking resistor. The
present fault is signaled via isolated NO and NC contacts.
After fault elimination, the thermal circuit breaker can be reconnected like a normal
miniature circuit breaker.
The thermal circuit breaker is installed on DIN rails (TS35).
UL and cUL approval
The thermal circuit breaker has the cRUus approval, independent of the application in-
verter.
