Abstract

An overvoltage protection device (2) has a plurality of varistors (51) fitted in a housing, whose earth electrodes are electrically interconnected via a strip (58). The mains electrodes (53) of the varistors are connected to contacts (34) via separators (60, 61). The separators consist of a push-rod in the form of a tubular rivet (60) connected to the electrodes (53) via a soft-soldered point (61). The push-rod (60) can move in a guide (100) of insulating material. One end of each push-rod (60) act together with a rocker (70) shared by all the separators which can pivot in the overvoltage protection device. On triggering, i.e. when one of the varistors (51) is overloaded, the soft-soldered connection (61) opens and the push-rod (60) concerned, actuated by a release spring (62), pivots the rocker (70) so that further switching operations are triggered. The rocker (70) also bears an indicating device (90, 91) visible through a window in the housing of the overvoltage protecting device (2), making it possible to see from outside that one of the separators (60, 61) has been triggered. As a single rocker (70) is allocated to all the separators, the design of the overvoltage protecting device is simple.
