LOW VOLTAGE SURGE PROTECTOR
For Telecom/Datacom/Fire, Sound and Security
PC642 Series surge suppressor is a dual 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 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 surge suppressor performance and survivability.
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
TECHNICAL BULLETIN # 2015.
