ABSTRACT:
A module for the protection of multiwire lines against overvoltages comprises a casing formed by a receptable and a terminal carrier plate. The terminal carrier plate comprises a pair of terminals for each wire of the multiwire line, and an earth terminal. Overvoltage diverters are connected to said wires and each have a first electrode soldered to a U link which connects, the two terminals of each pair of terminals, and a second electrode soldered to a transverse bar itself soldered to an extension of the earth terminal. The subassembly connected to the terminal carrier plate is disposed within the receptacle and is potted in a plastic potting substance. This module may be used for the protection of telephone lines.
