Features ■ Greatly reduced maintenance ■ Sealed solid-state device to ensure long life ■ Longer service life even in hostile environments ■ Fail-short device ■ UL Listed ■ Meets Telcordia GR-974 ■ Tighter control over the operating voltage ■ Reduced maintenance calls, fewer equipment failures and quieter lines ■ Consistent performance 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.
