Edco PHC-043 Series


Edco PHC Series Two-Pair Signaling Circuit Protector Surge Protection Device.  This price includes the PCB1B separate base.
The Edco PHC Series is designed to protect two pairs of wires specifically for alarm and security systems where operating currents can be as high as 5 Amps. Electrically, the Edco PHC Series is a rugged series hybrid implementing a staged complement of MOVs, copper wound inductors and Silicon Avalanche Diodes. This design reduces series resistance to 0.2 Ohms per pair. These products are intended to mate with an Edco PCB1B-WKEY gold-plated female terminal connector (which is included in Windemuller price).
The Edco PHC modules plug into a base assembly (Edco PCB1B), which can be mounted to any flat surface and should be located as close as practical to the protected equipment. Terminal 1 and/or terminal 10 should be connected to Building-Approved Ground with 12- or 10-gauge solid wire.
