Emerson R4B1S 5 Pin Protection Module Simple Type: System

The 5-pin protector modules protect personnel and equipment from excessive voltages and currents induced on telephone lines or local ground by lightning and AC power system faults. All modules feature industry standard 5-pin bases for use in central office, remote terminal, building entrance, and customer premises applications. All modules are available with or without a heat coil to protect against sneak currents. When a sneak current is induced on the line, the heat coil responds by permanently grounding the line to prevent damage to line cards and sensitive equipment. Carbon Protector Modules feature a carbon air gap and fail-safe mechanism that shorts to ground when a voltage exceeds its rating. A detent position disconnects the equipment side while protecting the line side (OSP cable). These modules are used where transients are not frequent or cost is a major factor.
