Tupavco Ethernet Surge Protector PoE+ Gigabit - Gas Discharge Tube for Full Protection - Mounting Flange - RJ45 Lightning Suppressor - LAN Network CAT5/CAT6 Thunder Arrestor - GbE 1000 Mbps (10 Pack)

Ethernet Surge Protector is a surge protection device (SPD) that is inserted inline on an RJ45 CAT6/CAT5/CAT5e cable to prevent damage of electronic networking equipment. Powerful surges that the device protects against include direct lightning strikes, voltage spikes, or PoE overvoltages. Despite the primary protection (a direct strike to a line), the thunder arrestor also offers secondary protection, which will arrest EMF induced surges (nearby lightning). Ethernet Surge Suppressor TP302 use a Gas Discharge Tube (GDT) on all 4 pairs (8 wires). Gas discharge tubes dissipate the voltage transient through a contained plasma gas which harnesses excess voltage in the incoming power and releases it safely.

It ensures the safety of a wide array of valuable components such as network hub, switch, router, modem, bridge, repeater, or any part of ISP (internet service provider) network or LAN system. POE Surge Protector allows a single RJ-45 cable to provide both data connection and electric power to device such as wireless access point, IP and security camera, VoIP phone, computer and others. Surge Arrestor TP302 is designed to protect PSE (power-supply equipment) connected to a network from transient overvoltages. The ethernet surge protector PoE supports both Mode A (Pins 1, 2+ 3, 6-) and B (7, 8+ 4, 5-) of the 802.3 af standard for supplying DC power.

802.3 af (PoE) can deliver up to 15.4 watts per port over Cat5 cables with 12.95W assured to be available at the powered device, while 802.3 at (PoE+) can deliver up to 30 watts over network cables with 25.5 watts available to devices. For that reason, PoE Plus is also known as High PoE. Ethernet surge protector allows PoE injected into the LAN cable at a voltage up to 60 volts DC, and typically 48 VDC is used. Mounting flange on the both sides of lightning suppressor allows easy mounting to a wall, network panel, cabinet, or rack attaching by screws (not included).
