Residual current circuit breakers serve to disconnect sections of an electrical supply system from a voltage source in the event of fault currents, for example caused by insulation faults. Such residual current circuit breakers are different in terms of their operation in mains voltage-independent and mains voltage-dependent residual current circuit breaker, the voltage dependence relates to the function of detecting fault currents and the trip unit.

If there is an insulation fault, the resulting fault current is detected by the detection unit and a trigger signal is output to the trigger relay, which subsequently leads via a switch lock for disconnecting the contacts and thus disconnecting the faulty distributor system from the voltage source. According to the known prior art fault current protective switch with standardized values with respect to the fault current current amplitude (for example, 10mA, 30mA, 100mA), the fault current quality (eg pure sine wave current = "AC", pulsating sinusoidal current with direct-current component = "A", DC = _"B")> and classified according to the type of tripping (instantaneous, short-time delayed, selective), which are only solved with certain specified parameters, which results in the intended use of the residual current circuit breaker.

A disadvantage of these residual current circuit breakers is that they are only suitable for a specific requirement. Due to the large number of possible designs results in a large parts cost which leads to high costs.
