Abstract (en)

[origin: WO2019238453A1] The subject of the invention is a surge arrestor (1), having a housing (2) comprising a column of electric resistors (7), and a first end (14) comprising a plug-in device (3, 4) and a second end (13) comprising a pressure relief device (12, 20, 30), characterized in that the pressure relief device has a cover (12, 30) which is fixed to the housing (9) in a fluid-tight manner by a clamping action, wherein the clamping action is dimensioned such that in the event of a malfunction of the surge arrestor (11), a buildup of pressure in the housing (9) overcomes the clamping action and a fluidic connection from the interior (8) of the housing (9) to the surroundings is created.
