A gas-filled surge arrester includes at least two electrodes, a hydrogen-containing gas filling and an activating compound applied to at least one of the electrodes. In order to ensure the required operating behavior of the surge arrester even at temperatures to 40%, the activating compound contains nickel powder in an amount of 30 to 35% by weight and potassium silicate in an amount of 25 to 30% by weight as basic components, sodium bromide in an amount of 15 to 20% by weight, as well as aluminum powder, sodium silicate and barium titanate as further components each in an amount of 5 to 10% by weight.

Gas-filled surge arrester wIth an activating compound formed of a plurality of components

A module is provided which includes two gas-filled surge arresters arranged next to one another in a housing. An auxiliary discharge gap and a short-circuit device is associated with each surge arrester. One side of each surge arrester is in contact with a plate, which forms the ground, as well as the stationary electrode of the short-circuit device. On the other side, the plate is in contact with two varistors which form the auxiliary discharge gaps. A cap, forming the movable electrode of the spring-loaded short-circuit device is placed on each varistor with a meltable spacer between them.
