Ethernet surge protectors are designed to protect network cables and devices from power surges. A power surge is a sudden increase in voltage. For example, when lightning strikes the electric lines near your house or business, it can result in a power surge.

When this happens, the energy comes through your cable Ethernet-enabled line devices – which are typically made of copper and makes their way to your computer and internet equipment. If you have one of these devices plugged in when the power surge happens, it can cause irreparable damage.

To prevent this unwanted happing to your Ethernet-connected devices, you should use a protector that can prevent damage by cutting off the electricity supply when it detects a power spike.

So using this device (Ethernet protection), you can rest assured knowing that all of your Ethernet lines are safe from harm. You won’t have to worry about expensive repairs or downtime ever again! This will be one purchase you’ll never regret making.

However, here I will share the top 7 best Ethernet surge protectors for this year. It also includes frequently asked questions about these products.

Buying Guide

There are many things that you should know when you are going to select an Ethernet surge protector. Below are the key factors that you need to consider.

Strong Housing

An Ethernet protector with strong housing increase prolongs of the device. If your Ethernet protection device is stronger, it means that it will serve you for a longer time. So try to find a device with strong housing.

Data Speed Rate

Data speed rate is a big thing to get a faster speed of any Ethernet connection. So you should buy one that has high data speed rate. Try to find an Ethernet protection device that can provide you with a minimum of 1000 Mbps which is the ideal speed of Ethernet.

Protection Capacity

You also need to consider the protection capacity of any device that you want to buy. Ensure that the surge protector that you want to buy has enough capacity to protect your devices from voltage fluctuations. You may ask yourself how you can know the capacity of any device. The answer is by reading its specification sheet, where all information about the device is written.

Power indicator

You also need to consider having a power indicator in your protector. If you find a device with a power indicator, it will be easy for you to monitor the power supply. Although most of the top-rated data protection device has power indicators.

Number of Ports

I think this is the most important buying factor because multiple ports in any device will help you to plug multiple connectors at the same time. Also, if one port is damaged, you can try another port to plug in your device. It also will reduce your cost to buy another one for multiple Ethernet-related devices.


You also need to consider the warranty period of the surge protector that you want to buy. If you find a device with a longer warranty, it will be of great advantage to you because it will serve you for a longer time. So choose a device with a long warranty if you want value for your money.


Do I need to be an electrical engineer when I install my Ethernet surge protector?

Definitely, no. You do not need to be an electrical engineer when you install your Ethernet protector because it is easy to install. So you will be able to set it up without any struggle.

How much is an Ethernet surge protector?

An Ethernet protector has a wide price range. It depends on various factors including the type of protector, features, and so on. You can choose a device that you can afford so that you do not strain yourself.

How many Ethernet surge protectors can I hook up to my modem?

You will be able to connect more than one Ethernet power protector to your modem. But I think, one surge protector device is enough in most cases.

Where should you mount the surge protector?

You should mount the surge protector in a dry place where it will be safe from dust and water. Moreover, you should not drill holes because it will damage the device.

What is Gas discharge?

Gas discharge suppression protects critical data lines. Standard ESDs divert excess electrical charge onto the attached ground which could result in lost data or system crashes.

Is it good to use a power strip ethernet surge protector?

Yes, it is good to use a power strip as long as the device supports POE. Also, using a power strip that has an ethernet, alarm, and UPS will be beneficial. But in this case, you should choose an Ethernet protection surge protector power strip that comes with a warranty.


An Ethernet surge protector is a small device that protects your network against voltage surges and electrical interference. Typically, the data transfer speed for an Ethernet protector is 10 million bits to 1 billion bits per second. So you should check the data transfer rate (minimum recommend speed 1000 Mbps).

However, choose a device based on your budget, needs, and the type of Ethernet surge protector that you need. You can choose any of them from the above list and also follow the guide to find the best one.
