Abstract
A protective switching device, such as a differential-current circuit breaker, having a corebalance transformer which monitors a line network and which, via a tripping circuit and an actuation circuit, actuates a release which is coupled to a switching mechanism in order to operate a power breaker. The invention provides that a tripping circuit, which can be tripped by means of a remote tripping signal, is connected to a transformer which can be actuated on the secondary side and whose primary side is connected to an actuation circuit of the release for remote tripping of the protective switching device.
