About this product
The Clearline DIN Rail Gigabit In-line Protector safeguards your Power over Ethernet (PoE) LAN devices including switches, IP cameras and wireless APs from surges, lightning and electrostatic discharge while preserving gigabit network speed and full data integrity.
Overview Summary
Product: Clearline DIN Rail Gigabit In-line Protector PoE Mode A+B
This compact surge protector is designed to defend PoE network equipment from damaging voltage spikes, lightning-induced surges or electrostatic discharge - ideal for installations with IP cameras, PoE switches or access points requiring reliable, uninterrupted performance. It protects all eight conductors of the Ethernet cable and supports both PoE Mode A and Mode B (compliant with IEEE 802.3af), making it a versatile inline safeguard for modern Cat5e/Cat6 network infrastructures. With negligible insertion loss and support for full 1000 Mbps data speeds, you retain gigabit performance while adding robust surge protection.
Engineered for rack or DIN-rail mounting, this protector fits neatly into network cabinets or distribution points and delivers peace of mind for sensitive data and power lines. It is backward compatible with 100Base-T networks, offering flexibility across older and newer network deployments.
Performance tier: Professional / Industrial grade
Uses: Protecting PoE cameras, PoE switches, IP network devices, LAN backbone protection, lightning surge protection
Description
The Clearline DIN Rail Gigabit In-line Protector is purpose-built for those who want to secure their PoE network infrastructure without compromising performance. Whether you operate IP security cameras, wireless access points or network switches powered via PoE, this unit intercepts dangerous surges and discharge events before they reach your sensitive equipment. It protects all eight wires in the Ethernet cable and supports both PoE power configurations - Mode A (power via data pairs) and Mode B (power via spare pairs) - ensuring compatibility with a wide range of PoE devices compliant with IEEE 802.3af standards. Its design introduces negligible insertion loss, so your network retains full gigabit throughput while enjoying enhanced protection. The compact 90 x 18 x 55 mm housing mounts easily on a standard DIN rail, making it an unobtrusive but vital part of any structured network cabinet or install. This protector is especially valuable in environments prone to lightning, electrical surges or unstable power, such as outdoor CCTV setups, remote AP installations or industrial network rooms.
