Abstract
A circuit breaker includes: at least one external conductor section from an external conductor supply connection in the circuit breaker to an external conductor load connection in the circuit breaker; and a neutral conductor section from a neutral conductor connection in the circuit breaker to a neutral conductor connection in the circuit breaker. The at least one external conductor section includes a mechanical bypass switch and a first mechanical isolating switch which are serially arranged. A second mechanical isolating switch is arranged in the neutral conductor section. A semiconductor circuit arrangement in the circuit breaker is connected in parallel to the bypass switch. A current measuring device is arranged in the at least one external conductor section that is linked to an electronic control unit in the circuit breaker. The electronic control unit operates the bypass switch, the first and second mechanical isolating switches, and the semiconductor circuit arrangement.
