ABSTRACT:
A weatherproof station protector module for communication systems includes a hollow housing on which is disposed a pair of weatherproof line terminals that extend into the hollow housing and a ground terminal. A holding assembly is affixed to the ground terminal within the hollow housing and is adapted to receive a surge arrester therein. The surge arrester may be a three terminal device or a pair of two terminal arresters with one electrode of each connected to the ground terminal and each one of the other electrodes being connected to a line terminal. The holding assembly for the surge protector may include a thermally sensitive material disposed between the surge arrester ground electrode and the line connections, thereby providing both overheat protection by positively shorting the line terminals to ground if the overvoltage protection should overheat as well as providing back-up surge arrester protection by means of a back-up air gap provided by a dielectric disposed between the line terminals and the ground connection. The unit is completely sealed and therefore impervious to the weather.
