ABSTRACT:
A surge protector particularly adapted for use with telecommunication equipment is non-conductive during normal operation and becomes conductive upon surge conditions of a first level and provides a short circuit condition when subjected to surge condition above a second, greater level. The protector comprises a semiconducting chip (16) disposed between first (32, 32') and second (30, 30') electrodes and is provided with an environmental seal (60, 60') shrunk abut the outer peripheral surfaces of the electrodes while being non-adhering to both provide contaminant protection and free slidability of the electrodes within the sleeve.
