Surge arrester

Abstract

Surge arrester with a spark gap (10) formed between opposing electrodes (6, 7) for dissipating an overvoltage, characterized in that: ◯ a wear element (20, 200) is arranged in the spark gap (10) between the electrodes (6, 7), ◯ the wear element (20, 200) is made of a material which is subject to material wear with each dissipation of an overvoltage, ◯ and the wear element (20, 200) is part of a wear indicator (30), ◯ and the wear indicator (30) indicates material wear and / or breakage of the wear element (20, 200).
