Abstract

The disclosure relates to a circuit breaker with a monitoring device having an electronic switch and a mechanical changeover switch, where the mechanical changeover switch has a first terminal, a second terminal and a third terminal, where in a neutral position of the mechanical changeover switch the first terminal is connected to the third terminal and where in an operating position of the mechanical changeover switch the second terminal is connected to the third terminal, where the electronic switch is connected to the third terminal of the mechanical changeover switch as a series circuit, where when switching on the circuit breaker in a first switching state, initially the electronic switch is activated, where a measurement is taken at the first terminal using the monitoring device to determine whether essentially the same potential is present at the first terminal as at the third terminal and, it this is the case, the electronic switch is activated and the mechanical changeover switch is in an operating position in a subsequent additional switching state. Furthermore, the disclosure relates to methods for the circuit breaker.
