If you are looking for value for money quality and great reviews, you should just get WatchfulEyE WTH-SG/RJ45-S. It is our best editorial pick among the other Ethernet surge protectors based purely on the many great reviews and Plug-and-Play (PnP) simplicity – no complicated setup needed. 😉

Not only is it compatible with up to 1000M Base-T Ethernet systems, but it also offers a 2-steps surge protection mode that releases and reduces the sudden intrusion of power surges in addition to providing a TVS Line to Line surge protection.

This WatchfulEyE Ethernet surge protector is super lightweight (5 grams) and is most suitable for direct in-Line plug in to all your network communication devices like Internet modem, routers and switches at home or in the office.

These network surge protective devices may be what you need to avoid detrimental electrical spikes or over-voltage surges that could cause damages to your network/data communication devices like Internet and wireless routers, network switches – not to mention laptops or computers which are connected to those network equipment.

With built-in protective elements like GDT (Gas Discharge Tube) and TVS (Transient Voltage Suppression), the strength of electrical surges will be greatly minimized with these two-step surge protection modes.

These WTH­-SG/RJ45-S devices from WatchfulEye are extremely easy to set up within your home and office network.

Some surge protectors do come with Ethernet ports that perform similar tasks but they are usually bulky and can become very expensive if you happen to have many network communication devices at home or in the office.

These RJ45 surge protectors from WatchfulEye are compatible with 10/100/1000M Base-T Ethernet systems and work well with Cat6 network cables.

Bottom line: if you prefer hassle-free, easy to set up (Direct in Line Plug-in) Ethernet surge protection devices for your home or office network, you would not go wrong with WTH­-SG/RJ45-S from WatchfulEye.

At 22g each, this pair of outdoor network surge protectors can essentially double up as network cable extension as well as surge protection for your outdoor network devices such as POE antenna or router.

Have you ever been caught in a situation whereby the network cable is a tad too short and you wish there was an RJ45 coupler to help connect 2 network cables together?

Built with RJ45 8 pin female to female, this lightweight network coupler will save your day.

Each of the CERRXIAN network surge protectors comes with built-in 8 TVS anti-detonator which helps prevent powerful surge currents from thunders which may cause unexpected damages to your computer systems.

This pair of RJ45 surge protectors will be the perfect protection bridge between your Internet router and your computer and network equipment.

If you want something that is easy to operate and is compatible with both cat5,cat5e cable, you will not regret getting it.

Being compatible with PoE (Power over Ethernet) and 10/100/1000 Base-T networks, APC ProtectNet PNET1GB provides you with peace of mind with its Catastrophic Event Protection feature.

The MOVs and Thermal fuse components offer instantaneous reactions to damaging surges caused by lightning strikes, transient spikes and wiring faults and so on. In the event that these components are damaged due to damaging power surges, Fail-Safe Mode would kick in and all excess electrical current would NOT be able to reach your network equipment. As a result, your precious data and network communication equipment and devices would be safe from getting catastrophic damages.

This lightweight RJ45 surge protector is only 50g and provides 1 nanosecond response to unexpected power spikes.

APC ProtectNet PNET1GB is RoHS compliant and offers 10 years of repair or replacement as a standard warranty.

APC is renowned for manufacturing high-quality surge protection and UPS systems hence if you need an affordable Ethernet surge protection device capable of protecting your sensitive electronic equipment, PNET1GB  is highly recommended.

Built with Female to Female interface connector, installation is a breeze. Do note that the yellow/green wire must be grounded, preferably near to the network equipment.

This PoE outdoor RJ45 surge protector weighs only 45 grams and with it solid external housing, it is able to protect against damages caused by insects or any exterior damages.

If you are someone safety conscious, you will be happy to know that this RitaAV surge protector comes with spark gap tubes that lower explosion risk and overheating during hostile electrical surges.

You do not need to get this if you do not have any network communication device installed outdoor. By the way, do not get this until you read our review on Tupavco TP303 (another outdoor Ethernet surge protection device) below. 🙂

This mountable RJ45 surge protector also offers both Line-Line and Line-Ground protection modes.

The Line-to-Line mode helps prevent short circuits (between different nodes in the network) while the Line-to-Ground mode prevents short circuits from happening between network nodes and the earth.

I like the fact that this network surge protector provides multi-directional surge protection which means it does not matter which side the network equipment is connected to. When a power surge comes along, it will protect the opposite end of the connection interface.

If you have a lot of network communication devices or workstations at home or in the office, it is highly recommended to get one Ethernet surge protective device for each network node in the network.

Having physical space constraints is no longer an excuse for not getting this Tupavco surge protector as it can be easily mounted via the mounting flange.

All in all, I have to say this Ethernet surge protector deserves our editorial recommendation. Get this if you are not technically savvy and just want a simple to setup network surge protection device.

In addition to whatever features that come with Tripp Lite DTEL2, it is only right to mention that it caters to surge protection for both Network and Phone lines.

That means if you can use it for both RJ45 (network) or RJ11 (phone) communication devices at home or in the office.

Just like Tupavco TP302 above, Tripp Lite DTEL2, too, offers comprehensive protection for electrostatic discharge, lightning and faulty wiring.

Bottom-line, if you are an affordable Ethernet surge protector from a trusted brand to safeguard your phone and network equipment (e.g. Internet routers and modem), this should be an easy buying decision for you.

This Ubiquiti RJ45 surge protector is also capable of protecting your network devices against ESD (Electrostatic Discharge) as well as voltage surges and transients. This Ethernet surge suppressor will prove to be the worthy middleman between your Network and PoE equipment and end-user network nodes that use RJ45 connections. E.g. PC workstations and laptops

This 80-gram network surge protection device comes with both female connectors within the box which helps connect and safeguard both sides of the network should any electrical surges come along.

Get this if you do not have high expectations and are happy with the standard protection of all your network equipment.
