    摘要: A circuit breaker is disclosed. A Rogowski converter is checked for wire breakage by applying the Rogowski converter with a voltage which is output by a digital/analog converter in response to a digital signal. The digital signal is dependent on the switch rated current of the circuit breaker.

    摘要: In order to provide a high impedance between two sensor terminals, for instance for connecting a Rogowski transducer to a circuit breaker, but to prevent the coupling-in of interference signals in the case of a non-connection to the terminals, two auxiliary terminals are connected. In at least one embodiment, they are connected in such a manner that in the basic state, the sensor terminals are short circuited but in the case of a connection, for example of a plug to the sensor terminals and simultaneously to the auxiliary terminals, the short circuit is canceled with external short circuiting of the auxiliary terminals.
