Abstract
In order to provide a circuit breaker, in particular a residual-current circuit breaker or residual-current device, having a variable time delay, which firstly has a stable no-trip response to short-term fault currents and secondly has a particularly short tripping time both in the event of sinusoidal fault currents and in the event of non-sinusoidal fault currents, a delay circuit is provided which comprises two series-connected comparators with a time-delay module connected between them. In this case, there is a smoothing module upstream of the first comparator.
