Model C-303™ 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 tin-alloy or gold-plated outside plant and central office pins; the 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.
• Tin-alloy plated pins can be used when the protector receptacles are tin-alloy plated.
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.
11-Type Protector Module
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.
Specifications are subject to change without notice.
The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.
Users should verify actual device performance in their specific applications.
