An electrical protective arrangement for an electrical installation has a fault current protection apparatus with a detection device for sensing a fault current and an evaluation device for comparing the sensed fault current with a threshold value. A tripping signal is output by the evaluation device if the sensed fault current exceeds the threshold value. A communication module is configured to send fault current data with information pertaining to the sensed fault current and to receive operating data for setting an operating state for the evaluation device.

Electrical protective arrangement for an electrical installation, and associated method

A compact residual current protection device is connected to a circuit breaker or a load break switch for external tripping and includes a detection device for detecting a residual current and a tripping device which is actuable by the detection device for tripping the circuit breaker as a result of actuation by the tripping device. A connection device is connected to the tripping device for connecting a switching device. The detection device and the tripping device are constructed in such a way that the tripping device is able to be tripped through the connection device by the switching device independently of the detection device. An electrical protection configuration is also provided.
