Abstract

A circuit breaker includes: at least one external conductor section from an external conductor supply terminal of the circuit breaker to an external conductor load terminal of the circuit breaker; and one neutral conductor section from a neutral conductor terminal of the circuit breaker to a neutral conductor load terminal of the circuit breaker. A mechanical bypass switch is arranged in the at least one external conductor section. A semiconductor circuit arrangement of the circuit breaker, which semiconductor circuit arrangement comprises a four-quadrant switch, is connected in parallel with the bypass switch. A current measuring arrangement is arranged in the at least one external conductor section and is connected to an electronic control unit of the circuit breaker. The electronic control unit is configured to operate the bypass switch and the semiconductor circuit arrangement in a prespecifiable manner. A voltage-dependent resistor is arranged in parallel with the bypass switch.
