ABSTRACT:
A miniature station protector module for communication systems includes a hollow housing into which is disposed a pair of line terminals with a ground terminal therebetween. The line terminals extend into the hollow housing and include thereon a back-up surge arrester in axial alignment with each of the terminals, either a three terminal surge arrester or a pair of two terminal arresters may be utilized having one electrode connected to the ground terminal with the other electrodes being connected to the line terminals. The holding assembly for the surge protectors includes a ground bracket which is adapted to receive the surge protectors and includes a thermally sensitive material disposed between the surge arrester electrodes and the ground connection 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.
