Schneider Electric PC642C-030LC LW CAP Surge Suppressor

Keep cameras, network switches and monitoring gear online with the Schneider Electric PC642C-030-LC surge suppressor — a compact surge protection module engineered for security and networking environments. This dual-pair (four-wire) module uses three-stage hybrid technology (gas tubes plus silicon avalanche components) to arrest fast over-voltage transients before they reach sensitive Ethernet ports and surveillance devices. Built-in resettable PTC fuses mitigate sneak and fault currents by increasing resistance during overloads, then self-restore when conditions normalize—reducing truck rolls and costly replacement parts. At just 2.4" deep x 1" wide x 1.8" high and weighing 2 oz, the unit installs unobtrusively in racks, junction boxes, or inline with data lines. The PC642C-030-LC is purpose-built for security integrators, IT managers and facility engineers who need reliable protection for monitoring, CCTV and networked access control systems. Backed by Schneider Electric’s quality, this surge suppressor extends equipment lifespan and improves system uptime. Add it to your next security or networking deployment to safeguard critical infrastructure.
