A solid state protector unit has a single voltage protection device shared by both tip and ring conductors to protect telephone equipment in a central office or other location from surges of voltages in either tip, ring, or both tip and ring conductors. The voltage device has a surge-suppressor sandwiched between two metal plates. Each of these pairs of metal spring clips retain a pair of diodes in contact with and on opposite sides of the two metal plates. When a voltage surge exceeds a predetermined threshold, the surge-suppressor turns on and permits a current to flow through it to a ground, thereby protecting the telephone equipment from voltage surges. Heat generated for a sustained period from the voltage device or from the current device will cause the current device to be grounded permanently.
Apparatus for protecting telephone equipment in a central office or other location against sneak currents or surge voltages by conducting said sneak currents or surge voltages or both to ground potential, said apparatus comprising
Apparatus for protecting telecommunications equipment from spurious voltages by dispersing a spurious voltage that appears on a telecommunications line to ground potential via grounding means, the apparatus comprising;
An electrical protector assembly for protecting a circuit against excessive current increases and voltage surges, the protector assembly comprising:
An electrical protector assembly comprising:
