Edco PC642C-T1-TWR 150ma 300V T1 Line Surge Protector.

PC642C-T1-TWR 300V 2-Pair T1 Line Protection.

The Edco PC642C-T1-TWR surge suppressor is specifically designed to protect T1 lines at base station sites by implementing three-stage hybrid technology. This twopair, solid-state 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 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 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.
