For Telecom/Datacom/Fire, Sound and Security


The 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.

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 TECHNICAL BULLETIN # 2015.

Caution: The hybrid design of this product includes series resistance. Do not place this product in service on any signal line capable of supplying more than 150 milliamperes continuously.

NOTE: Wire wound resistors are used instead of "PTCs" on low capacitance models (PC642C-___LC) and models clamping above 60 volts (PC642C-200, 200D, 200X, 200LC).
