Abstract

A surge arrester includes a gas-tight discharge chamber that is formed by at least one insulating body and two electrodes. The electrodes extend into the discharge chamber and include an electrode spacing with respect to one another and a wall spacing with respect to the insulating body inner wall. The electrode spacing is equal to twice the wall spacing or is less than twice the wall spacing.
