Abstract
An overvoltage protection device for protection of an electrical or electronic device, with a housing, with input and output terminals for electrical conductors, with line paths which each connect one input terminal to one output terminal, with first arresters which are used for symmetrical protection between the active conductors and with second arresters which are used for asymmetrical protection between the individual conductors and the ground potential, the individual first arresters each being connected by their first terminal to a line path and by their second terminal to a common connecting point so that they are at a common reference potential and symmetrical protection between two conductors is implemented by two first arresters located in series to one another. The overvoltage protection device can also be used in signal circuits with several signal conductors and can guarantee reliable protection of a connected electrical or electronic device against overvoltages.
