DEVICE FOR ANALYSIS OF IN AN ELECTRICAL SYSTEM AND FROM THIS OCCURRING ground fault CONTROLLED SWITCHING DEVICE

摘要

The invention relates to a device (1) for analyzing ground fault currents in an electrical installation, comprising a current detection module (10) and a current analysis module (11). Said device (1) generates an electrical signal when ground fault currents arise. The signal causes an opening of the break contacts (20) or the blocking of the semiconductor switching components (D1-D6) of a switching device (2) that is connected upstream in the installation. The device (1) has a module (5) for coupling the electrical signal to the power supply lines (4).
