Description

Two-Pair (Four-Wire) Protection for Low-Voltage Data Lines. The STC-642 Series offers two-pair (four-wire) surge protection modules featuring three-stage hybrid technology. Gas tubes and silicon avalanche components protect equipment from overvoltage transients, while sneak currents are mitigated with resettable fuses (PTCs). These fuses are designed to increase resistance by several orders of magnitude when an over-current exceeds safe levels, automatically resuming normal operation when the over-current is removed. This self-restore capability significantly increases performance and survivability, with no need to open the cabinet to reset a circuit breaker or replace a fuse. The STC-642 card edge module is gold plated, double sided and is designed to mate with the gold plated female base connector (STC-PCB1B, sold separately). When snapped together, the data circuits pass thru the protector in a serial fashion from the four field side terminals to the four electronics side terminals. Terminals 1 or 10 of the base connector must be attached to building approved ground.
