ABSTRACT:
An electrical protector device (10) for grounding excessive voltage and excessive current to safeguard telecommunications circuits includes a heat coil assembly (100) for sensing and directing excessive current to ground, and a spark gap arrester (200), axially aligned with the heat coil assembly (100), for sensing and controlling excessive voltage. Whenever an overcurrent condition is encountered, heat coil mechanism (110) is displaced to provide metallic contact of the incoming line to a ground structure (300). In addition, the device is adapted to provide protected testing of both incoming pairs and office equipment. Two test points (123) formed as part of the heat coil assembly (100) are in contact with the individual wires of the incoming line. These two test points are accessible through apertures (402) in the protector housing (400).
