1. A module for protecting telecommunication devices against voltage surges, comprising:
- an insulated housing provided with a cover;
two gas-filled surge arresters arranged next to one another in the insulating housing, each of the surge arresters having a first electrode and a second electrode;
a respective auxiliary discharge gap connected in parallel to each of the surge arresters, each respective auxiliary discharge gap including a respective varistor having two contact surfaces;
a respective short-circuit device assigned to each of the surge arresters, each respective short-circuit device responding in an event of an overload, each respective short-circuit device having an axially movable electrode and a counter electrode, the movable electrode including a respective cap and being held at a distance from the counterelectrode by a meltable spacer, and a plug-in contact part leading to an outside of the housing, the plug-in contact part being associated with the first electrode of each of the surge arresters;
a common contact device leading to the outside of the housing, the common contact device including a plate, the plate forming the counterelectrode of both of the short-circuit devices, a first side of the plate being directly contacted by the second electrode of both of the surge arresters, a first one of the contact surfaces of each respective varistor being in direct contact with a second side of the plate, the respective cap and the meltable spacer of each respective short-circuit device being placed on a second one of the contact surfaces of the respective varistor, the meltable spacer of each respective short-circuit device being positioned between the respective cap of the respective short-circuit device and the second one of the contact surfaces of the respective varistor; and
an elastic,clip, each cap being electrically connected to the first electrode of the respective surge arrester via the elastic clip, the elastic clip securing each cap.

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.
