Product Description

cover1.png pc.png 


The PC642 Series surge suppressor is a dual-pair (4-wire) module implementing three-stage hybrid technology. This module addresses overvoltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses (PTCs). The PTCs increase resistance several orders of magnitude when overcurrents exceed safe levels. A normal state resumes when overcurrents are removed. The ability to self-restore in this manner significantly increases suppressor performance and survivability. UL 497BThe PC642 card edge module is gold-plated, double-sided and is designed to mate with the PCB1B gold-plated female terminal connector. 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 per Edco Technical Bulletin #2015.​
