4-Port (4 in/4 Out) RJ45 Ethernet Surge Protector, 10KV Lightning Arrestor, PoE++ Compatible, Gigabit Speed, GDT Technology, Metal Shielded, CAT5/CAT6, Wide Temperature with Flange Mount

[4 Pairs Port (4In/4Out) High-Capacity Design] Boasts 4 input and 4 output RJ45 ports (8-wire full protection for each port) to simultaneously safeguard up to 4 network devices, ideal for small-to-medium LAN setups. Supports 10/100/1000Mbps Gigabit Ethernet speeds with ultra-low insertion loss ( 0.5 dB), ensuring seamless data transmission without any performance degradation, even when all ports are in use. [Industrial-Grade Dual Surge & Lightning Protection] Equipped with premium GDT (Gas Discharge Tube) and TVS (Transient Voltage Suppressor) dual protection components, offering 20KV common mode and 1.5KV differential mode surge resistance, plus 20KA (8/20s) discharge current capacity.

Provides comprehensive line-to-line and line-to-ground bidirectional clamping protection for all 8 pins of each RJ45 port, with a lightning-fast response time 1ns to block sudden voltage spikes, electrostatic discharge, and lightning-induced transients. [Full PoE++ Compatibility & High Power Support] Fully compliant with IEEE 802.3 af/at/bt (PoE++) standards, supporting up to 120W power delivery per port (max 154W for High PoE++ devices at 48V DC) and 60V DC maximum input voltage. Works seamlessly with Mode A and Mode B PoE/PoE+/PoE++ devices, as well as non-PoE Ethernet equipment, and is compatible with CAT5, CAT5e, and CAT6 cables for wide-ranging applicability in diverse network environments.

[Durable Aluminum Construction & Flexible Installation] Features a rugged aluminum alloy housing that delivers exceptional heat dissipation, corrosion resistance, mechanical strength, and electromagnetic shielding, ensuring long-term reliable operation even in harsh industrial conditions. Comes with a 12AWG grounding wire for stable and safe grounding, dual-side mounting flanges, and a flexible DIN rail bracketsupports wall mounting, DIN rail installation, or desktop placement. Clear "IN" (incoming line) and "OUT" (protected device) directional markings enable hassle-free plug-and-play setup without complex tools or professional expertise. [Wide Operating Temperature & Versatile Application] Operates stably within an extreme temperature range of -40 to 185 (-40 to 85), making it suitable for both indoor and industrial environments with fluctuating temperatures.

Effectively protects valuable network equipment such as PoE cameras, routers, switches, modems, servers, and Ethernet-enabled devices from surge damage, minimizing downtime and replacement costs for home, office, commercial, and industrial network setups
