CNI 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 and theprotector modules have five contact pins. When inserted into the connector sockets, contact pins provide the following connections foreach 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 CNI C-303 Solid-State Protector Module family greatly surpasses the performance of two and three-element gas tubes as wellas 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 connectedtogether. Fast and easy disconnect of the central office pairs from the outside plant pairs is accomplished by pulling the fully insertedprotector 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 otherelectrical conditions that exceed the surge capabilities of the SSOVP device.
