Transient overvoltage protection device e.g. for telecomms. facilities

摘要

An overvoltage protection element for diverting transient excess voltages includes two electrodes (2) with an effective air breakdown spark path (3) between them. Each electrode (2) has a connector (5) with an associated obliquely positioned arcing horn (6), with both arcing horns (6) of the mutually spaced electrodes (2) together forming the air breakdown spark path (3). A quench-plate (23) arrangement comprising at least one preferably several quenching plates (22) is provided in the housing (4).
