Abstract

An overvoltage protection device for protection of low voltage electrical installations, has a device base part with terminals for phase conductors and ground or neutral conductors and at least one overvoltage protection element, with at least one arrester which is located in a housing. The base part of the device has at least one telecommunications contact which has a switch for remote indication of the state of at least one overvoltage protection element, the base part of the device having plug contacts which are connected to the terminals, and the overvoltage protection element having corresponding connector contacts so that the overvoltage protection element can be plugged onto the base part of the device. The overvoltage protection device is improved by the overvoltage protection element having an optical status display and the optical status display and the switch of the telecommunications contact being actuated via a common mechanical actuating system.
