Abstract
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.
