Abstract

See full text

The invention relates to an overvoltage protection device with varistors, wherein a first varistor and a second varistor are connected in series, wherein the first varistor has a thermal disconnector, wherein the first varistor has a lower operating voltage than the second varistor, and wherein the first varistor has a lower energy absorption capacity than the second varistor, with the first varistor heating up more in the event of an overload and thereby causing the thermal disconnector to disconnect.
