摘要： The invention relates to a differential current monitoring device for monitoring differential currents in power supply systems, having a first measuring current transformer and a measuring circuit for determining the differential current and having a computing unit for evaluating the differential current and for generating a switch-off signal. The differential current monitoring device has a device for detecting arcs, the integration of which according to the invention can considerably reduce the technical effort needed to monitor the differential current, combined with the arc detection, in comparison with a functionally and spatially separate arrangement of both protective measures.
