If you are unfamiliar with connections between network equipment and devices , there is an easy-to-understand network diagram from Qooltek on the left.

Besides safeguarding sensitive electronic equipment from power surges and spikes, Qooltek ST-RJ45 also comes built with material that offers high insulation resistance and durability seems obvious with its cast aluminum casing.

If you are like me who likes uncomplicated setup, this Ethernet surge protector from Qooltek which is also RoHS compliant should be in your to-buy list.

With a surge response time of about 1 nanosecond, there is no much fault we can find with this network surge protection device which is highly affordable.

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

The MOVs and Thermal fuse components offer instantaneous reaction 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 repair or replacement as standard warranty.

APC is renowned for manufacture high quality surge protection and UPS system 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, preferable 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 with 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 circuit 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 are 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 nodes in the network.

Having physical space constraint 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 additional to whatever features that come with Tripp Lite DTEL2, it is only right to mention that it caters 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
