Abstract
A residual-current circuit breaker includes at least one summation current transformer through which a first lead and a second lead of a network to be protected are guided. At least one secondary winding is arranged on the summation current transformer and operatively connected, at least indirectly, with an energy storage element. A trip element is operatively connected with break contacts in the first and second leads. In order to reduce expected cut-offs of a network to be protected, an electric signaling device is operatively connected, at least indirectly, with the energy storage element.
