Device for diverting surge currents or transient overvoltages
First Claim
1. Device for diverting surge currents or transient overvoltages (1), with a switching stage (2) and a switching element (3), such that the switching stage (2) is so designed that upon identification of an overvoltage or a surge current the switching element (3) is switched on,whereinthe switching element (3) is a reversible semiconductor switching element and the switch-on event is achieved by operating the switching element (3) outside of the specified parameters.

Abstract
The subject matter of the invention is a device for diverting surge currents or transient overvoltages (1), with a switching stage (2) and a switching element (3). The switching stage (2) is so designed as to switch on the switching element (3) upon identification of an overvoltage or a surge current. The switching element (3) is a reversible semiconductor switching element, while the switch-on event is achieved by operating of the switching element (3) outside of the specified parameters.
