Earth device, plug-in breaker and distribution board

摘要

A grounding apparatus for a distribution device having a functional element and a grounding contact point includes a grounding rail having opposed end sections provided with a holding part for fitting the grounding rail to the functional element. An electrically conductive contact spring on each of the end sections extends outwardly beyond the holding part to make contact with the grounding contact point. A safety plug for use with the grounding apparatus includes an overvoltage protection device connected to a conductive contact tongue for contacting an electrical cable connected to the functional element. The overvoltage protection device has a grounding electrode and a conductive fitting in electrical contact with the grounding electrode is provided with an insulation-displacement terminal for connecting the safety plug to the grounding apparatus. A handling apparatus having a base body with a retaining groove is provided for installing the grounding apparatus to the distribution device.
