Abstract (en)

[origin: WO2022157378A1] The invention relates to an overvoltage protection device (10) to protect an electrical system from transient overvoltages, having a voltage-limiting protection component (18) and also a voltage-switching protection component (20). The voltage-limiting protection component (18) and the voltage-switching protection component (20) are connected in series. The voltage-limiting protection component (18) is rated such that the voltage-limiting protection component (18) satisfies the condition UB=UN/KX, wherein UB is the rated voltage of the voltage-limiting protection component (18), Un is a nominal voltage across the voltage-limiting protection component (18), and Kx is an adjustment parameter, the value of which is at least 2.
