5-Pin Solid-State Protector Modules

Bourns

Model C-303™ 5-Pin Solid-State Protector Modules provide surge protection in a 5-pin type protector for use in central office

connector, remote and building entrance terminal applications. The housings are made of colored self-extinguishing insulating

material. The protector modules have five contact pins. When inserted into the connector sockets, contact pins provide the following

connections for each cable pair:

• protection ground that also acts as a polarization pin

• tip and ring to the outside cable

• tip and ring to the central office equipment

Protector modules are available with gold-plated outside and central office pins; grounding pin is always tin-alloy plated.

• Protector modules with gold-plated pins are intended to be used in connectors with gold-plated protector receptacles.

The Bourns

Model C-303™ Solid-State Protector Module family greatly surpasses the performance of two- and three-element gas

tubes as well as carbon, ensuring enhanced protection for sensitive switching equipment.

When the protector modules are fully inserted into the connector base, the outside plant and the central office pairs are connected

together. Fast and easy disconnect of the central office pairs from the outside plant pairs is accomplished by pulling the fully inserted

protector out to the “detent” position. Protection is still provided on the outside plant cable pairs.

The 5-pin module is designed to short-to-ground (also known as a “fail-short event”) when it encounters lightning, power cross or other

electrical conditions that exceed the surge capabilities of the SSOVP device.

11- and 12-Type Protector Modules

The 11-type modules provide voltage protection to wiring and

equipment. The 12-type modules provide voltage protection

and are equipped with heat coils for applications where sneak

current protection is required.

High-sensitivity heat coils protect digital equipment line cards

against overheating caused by prolonged currents, commonly

called sneak currents. Sneak currents may be caused by direct

contact with low-voltage power lines or from induction on

telephone lines caused by fault currents, overloads or

unbalanced loads on nearby power lines. The 150 milliampere

heat coils are sensitive enough to operate before component

damage occurs on most digital line cards. They carry normal

currents with ample safety margin and shunt potentially harmful

sneak currents safely to ground.

Medium sensitivity (350 mA) and PBX battery (1.2 A) heat coils

are also available.

12-Type Protector Module

* Metallic shunts close circuit by heat coil operation to ground

line and equipment directly or through heat coil resistance.

Heat coil operates due to sneak currents and power crosses.
