Edco PC642C020 Surge Suppressor/Protector

The Edco PC642 Series surge suppressor is a two- pair pair (four wire) module implementing three-stage hybrid technology. This module add resses over-voltage transients with gas tub es and silicon avalanche components. In addition, sneak and fault currents are mitigated with reset table 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 Edco PC642 card edge module is gold-plated, double sided and is designed to mate with the the Edco PCB1B gold-plated female terminal connector (sold separately). When snapped together, the data circuits "pass thru" the prote ctor 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 at tached to Buildi ng-Approved Grou nd per Edco Technical Bulletin # 2015.

PCB!B-WKEY may be ord ered along with PC642 module by addi ng "-Kit" to the end of the module part number (Example: PC642C-036LC-KIT).
