4-Pin Protector Modules
Bourns® 4-Pin Protector Modules are designed for use with the MPC Central Office Connector Block (QCM486-series) and QTPET Protected
Entrance Terminals. These modules are available with solid-state or gas tube overvoltage protection.
The 4-pin modules are designed to short to ground (also known as a “Fail-Short event”) when an electrical surge exceeds the capability of the
SSOVP device or gas tube. This feature provides protection for personnel and equipment until the surge condition has cleared. Protector
modules that “Fail-Short” must be replaced after the fault has been corrected.
The 4-pin modules are also available with an option for heat coil or Positive Temperature Coefficient (PTC) sneak current protection. This
feature protects digital equipment line cards against overheating caused by prolonged currents – referred to as sneak currents. Sneak currents
are caused by induction on telephone lines caused by fault currents, overloads or unbalanced loads on nearby power lines. They may also be
caused by direct contact with low-voltage power lines. The PTC is self-resetting; the heat coil operates by permanently shorting to ground and
must be replaced after the fault is cleared.
All 4-pin modules are equipped with a latching mechanism that will retain the modules when installed in the detent position or when fully
inserted. In the detent position, the equipment side of the circuit is disconnected from the outside plant pair. The latch must be depressed to
move the modules, thus ensuring that protector modules will not fall out (leaving the outside plant pair unprotected) or become accidentally
inserted. In addition, the modules are designed so they can only be inserted in the correct orientation.
