Abstract
A residual-current circuit breaker includes switching contacts and at least one residual current detector configured to determine a residual current signal. The residual-current circuit breaker is configured to bring about an opening of the switching contacts upon the detection of a residual current greater than a pre-definable tripping current. A first circuit arrangement is configured to inhibit tripping of the residual-current circuit breaker when a residual current occurs that has a duration that is shorter than half a period of a grid frequency of an associated electrical grid.
