ABSTRACT:
A protector module for use in protecting telephone lines includes an insulating base with two sets of line pins and a ground pin extending from one side of the base. Disposed on the other side of the base is a pair of spaced apart line contacts with one of the line contacts being coupled to one set of line pins and the other line contact being coupled to the other set of line pins and a ground clip assembly coupled to the ground pin and disposed between the line contacts. The ground clip assembly mounts a three electrode gas tube arrester having a pair of line electrodes and a ground electrode such that one of the line contacts is coupled to one of the line electrodes by a fusible element and the other line contact is coupled to the other line electrode by another fusible element. In response to a fault condition occurring on the telephone line coupled to one of the line contacts, the fusible element between that line contact and the line electrode melts, allowing the line contact to move toward the ground clip assembly such that the line contact makes electrical contact with the ground clip assembly. In one embodiment of the protector module, an insulating housing is detachably secured to the base in order to enclose the ground clip assembly, the line contacts, the gas tube arrester and the fusible elements.
