STC-642 Series Data/Signal Line Protection

The STC-642 Series of Surge Protection Devices are dual pair (four wire) modules using three-stage hybrid technology. This module addresses over voltage transients with gas tubes and silcon avalanche components. In addition, sneak and fault currents are mitigated with resetable fuses (PTCs). The PTCs increase resistance several orders of magnitude when over currents exceed safe levels. A normal state resumes when over currents are removed. The ability to self restore in this manner significantly increases suppressor performance and survivability.

The STC-642 card edge module is gold-plated, double sided and is designed to mate with the STC-642 gold-plated female terminal connector (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 PCB1B must be attached to building approved ground.
