Abstract
The invention relates to a surge protection apparatus () for protecting an electrical installation against transient overvoltages, having a voltage-limiting protection component () and additionally a voltage-switching protection component (). The voltage-limiting protection component () and the voltage-switching protection component () are connected in series. The voltage-limiting protection component () is dimensioned such that the voltage-limiting protection component () satisfies the condition U=U/K, where Uis the rated voltage of the voltage-limiting protection component (), Uis a nominal voltage applied to the voltage-limiting protection component (), and Kis a setting parameter the value of which is at least 2.
