ABSTRACT:
A protector for use in a telecommunications system to establish an electrical connection between two lines includes a base and at least two line terminals extending from one surface of the base. A ground terminal also extends from the one surface of the base and is spaced from the two line terminals. A circuit board is mounted on another surface of the base and has electrical paths on it leading to the at least two line terminals and to the ground terminal. An overload detector is mounted on the circuit board and establishes an electrical connection between the at least two line terminals by way of the electrical paths in normal operation and establishes an electrical connection between at least one of the at least two line terminals and the ground terminal by way of the electrical paths in the event of an overload condition. A fail short may also be provided to establish a permanent electrical connection between the at least two line terminals and the ground terminal if the overload condition exceeds the rating of the overload detector.
