Edco PC642C-036


Edco PC642 Series (Zone/Loop/Data).
The Edco PC642 surge suppressor is a two-pair (four-wire) module implementing three-stage hybrid technology. This module addresses over-voltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses (PTCs). The PTCs increase resistance in several orders of magnitude when over-currents exceed safe levels and resume a normal state 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 Edco PCB1B-WKEY gold-plated female terminal connector. When snapped together, the data circuits “pass through” the protector in a serial fashion from the four “Field Side” terminals to the four “Electronics Side” terminals. Terminals 1 or 10 of the Edco PCB1B must be attached to Building-Approved Ground per Edco Technical Bulletin #2015.
Windemuller price includes the PCB1B separate base.
