Aluminum RJ45 Surge Protector for Ethernet Networks Description A compact thunder arrestor designed to protect computer networking equipment such as routers, modems, IP cameras, and switches from voltage transients on Ethernet lines. Housed in a durable aluminum case, this lightning suppressor provides RJ45 cable protection for CAT5 and CAT6 installations while supporting 1000 Mbps gigabit Ethernet. Key benefits Protects network equipment from transient voltages caused by lightning strikes, electrostatic discharge, and ground surges that can enter through signal lines or chassis ground. Maintains network performance with support for 1000 Mbps links, suitable for gigabit Ethernet environments. Durable aluminum enclosure offers solid shielding and long service life in indoor or sheltered outdoor installations. Simple plug and play connection with a standard shielded RJ45 interface for fast installation and minimal downtime. Features Function: Surge suppression for Ethernet data lines to reduce the risk of damage to connected networking devices. Compatibility: Works with CAT5 and CAT6 cabling and standard RJ45 shielded ports used on routers, modems, network switches, PoE devices, and IP cameras. Material: Rugged aluminum case for mechanical protection and improved shielding against electromagnetic interference. Performance: Designed for 1000 Mbps Ethernet networks with shielded RJ45 connectors to preserve signal integrity. Installation: No configuration required. Inline plug and play device installs between network cable segments or at the point where the cable enters equipment or a building. Practical use scenarios Home network protection: Install between a modem and router to help reduce the risk of equipment damage from surges on the incoming Ethernet line. Security camera installations: Place the protector inline on long Ethernet runs to IP cameras, especially where cables pass between structures or outside areas, to reduce surge exposure. Small office or retail networks: Protect switches and PoEpowered access points by placing the device at patch panels or at device endpoints where cables enter racks or equipment enclosures. What to expect Inline suppression with shielded RJ45 connectivity for straightforward integration into existing cabling. Durable aluminum housing for reliable physical and electrical shielding. Compatible with standard CAT5 and CAT6 network deployments and designed to support gigabit speeds. This surge protector is intended as a protective component for data and communications equipment to help limit the effects of transient voltages on Ethernet signal lines. Install at cable entry points or at device endpoints for results.
