Rapidly changing thundering currents induce high voltages on electrical loops and twin-wires that can damage the insulation of the system. Various operations of the power system can generate operating overvoltage on the power cable.Some electrical equipment switching operations and short circuit trips can generate overvoltage (surge voltage) higher than the normal working voltage in the power cable, thereby causing damage to the electrical equipment.
Fixed interface shielding external EML,RFL and other electromagnetic interference.
Built-in 8 TVS anti-detonator, prevent thundering and other abnormal current through the network cable damage to your computer equipment.
Connector :RJ45 8 Pin Female to Female
Size:26 x 24 x 45mm
Colour: Black
Package: 2 x Network Surge Protector
Thundering protection, impact resistance, anti-vibration, anti-electromagnetic interference.
Plug and play without the need to install tools.
Easy to operate, compatible, and supports high power and low power devices.
Compatible with cat5,cat5e cable
How I installed:
Firstly The input of Network Surge Protector is connected to the external signal cable.
Secondly The output of the Network Surge Protector is connected to the signal input of the protected device.
Application:
Ethernet card, Repeater, HUB, Switchboard, Router or other Ethernet devices.

Seem decent. No signal loss or degradation that I can find. I learned a tough lesson and didn't add these in-line until after a surge came through a CAT5 cable and took out my fios modem and brand new OLED TV. Hopefully if it happens again, this will save me a huge headache.

We had a lightning strike that took out all sorts of stuff, mostly internet stuff including stuff that was on surge/UPS protection. I now have an earth grounded surge protector on the twisted pair that comes in from AT&T. We assume that's how it got in and spread. These are in-line and don't require an earth ground so I put one on my generator (lost the logic board on this) and one on the line between my gateway and my switch.

I bought these as my home is prone to near by lightning strikes. I have a large home wired network and use these on both ends of my long cable runs and before equipment connections. I hope they perform as excpected.

I had tried 2 other lightning arresters. One switched the signal from 4 to 5. The other, did not switch any signals, but would not work in my setup. Perhaps I should explain my set up. I have a micro wave antenna which captures a signal from my ISP and converts it to an Ethernet signal. We live on a mountain in Tennessee which is often struck by lightning. Therefore, I really need lightning protection on any wired connection. From the ethernet signal from the antenna I connect with an ethernet 8 rj45 unmanned switch which supplies my EERO gateway and the fiberglass connection to my office. The other 2 arresters would not work. This one seems to pass the ethernet signal flawlessly.It is not connected to ground. All of the other 2 are connected to ground. Whether it will protect against lightning I do not know. When we have another storm with cloud to ground lightning I will report again. Amazon lets one add to reviews.
