STC-642 Series Data Signal Line Surge Protective Devices

STC-642 Series Data/Signal Line Surge Protective Devices offer 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.
