Claim Text:
1. A redundant overvoltage circuit breaker with a rotational disk and with an added electronic assembly for extending a life span of an overvoltage component, characterised in that it has a gas discharge tube ( 3 ) connected in series with a coil ( 5 ) and a resistor ( 4 ) with a positive thermal characteristic, and a gas discharge tube ( 6 ) connected parallel to the gas discharge tube ( 3 ), the coil ( 5 ) and the resistor ( 4 ); that a common point of these two branches prevents a route of leakage current via gas discharge tube ( 3 ) of one of terminals, which can be connected to a line or neutral conductor, via a varistor to an earthing point; that there is no leakage current in any of these two branches, since the varistor is galvanically separated between the clamp terminal and the earthing point; that in case of increased current surges the gas discharge tube ( 6 ) discharges through a branch of the varistor ( 7 and 8 ) into the earthing point; that the varistors ( 7 and 8 ) each has its own rotational circuit breaker ( 9 and 10 ).
