Overvoltage discharge device

The utility model relates to an overvoltage discharge device, which is provided with a preassembled and electrically interconnected overvoltage discharger existing in a common shell, and an adapter type mechanism for electrical and mechanical connection is arranged on the shell in order to be directly arranged on a standard busbar system with a plurality of busbars. The mechanism has a spring element and a locking member, and the housing extends over the plurality of busbars over its longitudinal extent. According to the utility model, at least one longitudinal extension section of the shell is provided with a width concave part, so that a free space is formed, and at least one electrical component functionally separated from the overvoltage discharge device is accommodated in the free space. By means of the overvoltage discharge device, various different electrical components can be integrated in the busbar system in a space-saving manner. Therefore, there is no space shortage in thepower supply area, in par
