Patent ID: 7411769

Claim:
Overvoltage protection device for protection of low voltage electrical installations, comprising: 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, wherein the base part has at least one telecommunications contact which has a switch for remote indication of the state of the at least one overvoltage protection element, wherein the base part of the device has plug-in contacts which are connected to the terminals, and wherein the overvoltage protection element has corresponding connector contacts, so that the overvoltage protection element can be plugged onto the base part of the device, wherein the overvoltage protection element has an optical status display, wherein a mechanical actuating system is provided for actuating of both the optical status display and the switch of the telecommunications contact, wherein the mechanical actuating system has a first spring-loaded actuating means for actuation of the switch and a second spring-loaded actuating means for actuation of the optical status display, the first actuating means being located in the base part of the device and the second actuating means being located in the overvoltage protection element, wherein the first actuating means is actuated by the second actuating means, and wherein the first actuating means has a rocker, an actuating plunger and at least one spring, the rocker being movable out of a first position into a second position, by which the switch of the telecommunications contact is actuated; and wherein the rocker, the actuating plunger and the at least one spring being located in said device base part.
