ABSTRACT:
A line protector for a communications circuit comprises a housing, an over-voltage arrester received in said housing and having axially opposite electrodes and a ground strip for coupling one of the electrodes to electrical ground. An over-current arrester has at least one line contact for electrically contacting a communications line. A conductive sleeve electrically contacts a second communications line to be joined with the first communications line, the sleeve also being assembled with the over-current arrester and with the over-voltage arrester, such that the over-voltage arrester is held within the housing. The sleeve has projecting fingers for completing an electrical circuit between the second communications line and the other of the electrodes of the over-voltage arrester. A ground assembly is assembled with the sleeve within the housing and generally intermediate the over-current arrester and the over-voltage arrester for contacting the ground strip and providing a ground surface in an area intermediate the over-voltage arrester and the over-current arrester for grounding the second communications line which is in electrical contact with the line contact upon occurrence of an over-current condition.
