16 Lines/Ports RJ45 Lightning Protection for Gigabit 10/100/1000 (GbE) and High PoE+ Networks
The gigabit surge protector date rate of Gigabit 10/100/1000 (GbE) transfer supports an ultra-fast maximum data rate of 1 Gigabit per second (Gbps – 1000 Mbps) and does not affect the speed performance in the local area network. 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 TP303 is designed to protect PSE (power-supply equipment) connected to a network from transient overvoltages. The lightning protector PoE supports both Mode A (Pins 1,2+ 3,6-) and B (7,8+ 4,5-) of the 802.3af standard. 802.3af (PoE) can deliver up to 15.4 watts per port with 12.95W at the powered device, while 802.3at (PoE+) can deliver up to 30 watts with 25.5 watts available to devices. PoE Plus is also known as High PoE.
Installation
The rackmount must be properly grounded to work through the shortest path. Excess electricity will follow the path of least resistance. In most cases, a ground busbar on an electrical panel or network rack cabinet is already grounded and is typically the easiest way to ground the wire. Other options to ground RJ45 surge protector are grounding block on the breaker panel or grounding rod.
The lightning arrestor can be used with unshielded twisted pair (UTP) or shielded (STP) cables.
Protection Modes Line-Line, Line-Ground
The Line-to-Line ethernet surge protection mode helps protect against short circuits between different nodes of the network system while the Line-to-Ground mode protects against short circuits between the network node and the earth. As it is not known where the transient will happen, having both modes protected ensures damage is minimized. Nominal Discharge Current of 5KA defines the peak value of the current that can be passed through the SPD having a waveshape of 8/20μs microsecond where the RJ45 lightning arrestor remains functional after 15 surges.
Once the surge protector ethernet voltage exceeds its designed rating it “begins to clamp” and starts to conduct energy directly to the electrical grounding system. A bidirectional clamping on CAT5 surge protector allows levels above and below the reference voltage by clamping the voltage that can cause damage.
Each (of 16) ethernet surge protectors is replaceable
Investing in a easy to install surge protector rack with all of the needed features and proven reliability can be the safest and most cost-effective solution for protecting your whole Ethernet network.

Specifications
Multidirectional
Ethernet network surge protector works in both directions (IN/OUT), so the source input signal cable can be connected to any side. It is not important which side the equipment is behind, however the surge protector will protect networking equipment only on the opposite side of where surge occurs. To protect devices on both sides, it is recommended to have one of the surge protectors on each end of the RJ45 cable in the network topology.
- Nominal Discharge Current (8/20μs): 5 KA
- Nominal PoE voltage : <60V
- PoE current up to 1.2A
- PoE Mode Support Mode A and B for Power
- Tested standards IEC 61643-21, IEC61000-4-5
- Clamping Voltage Line-Ground: 72 Volts
- Clamping Voltage Line-Line: 72 Volts

These are the absolute best for protection of expensive sensitive equipmentJust make sure you ground it to a proper ground so that excess current can drain off the device.

No interference with signalI installed this surge protector between my cable modem and my router today. Easy peasy. Plug the Ethernet cables into each end (marked “Line” and “Equip”) and attach the ground terminal to something grounded. (I used a 12AWG solid wire and a ground screw on my uninterruptible power supply.) Running Ookla Speedtest verified no degradation of signal. Hopefully, I’ll never find out if it works.

No need for clips, screws directly onto panel with ground terminal provide.Product had a very descriptive list of what it could do,like grounding lug on panel must be used, can run POE and POE+,can also be used in VOIP and cameras.It also noted that two panels should be used, for roof or outside camerasa point entering the building and at server or network switch end.It noted the difference between diodes that fail after lightning surge and these that are gas diodes.

Very high quality surge protector.I was blowing one port on my router nearly every electrical storm. Frontier i think was getting tired of replacing them as i lost four routers in five months. I live on the highest natural point in central florida which is reported to have more lighting strikes than any place in the USA. Since i installed this i haven’t lost a Ethernet port and have gone through one hurricane and seventeen major electrical storms. When I installed it i used one of the ideas of another reviewer thank you by the way. I did not use the ground wire supplied by the vendor but ran a 12 AWG multi strand wire from the unit to a three prong 15 amp replacement; plug’s grounding pin. All other pins or spades on the plug remained empty and covered internally with heat shrink. Plugged into a outlet within three feet of the surge protector. Fantastic solution will now add these to all my ports entering the router and at my ORBI Wifi units.

Does not seem to weaken signal.Through my career in instrumentation I have seen that copper wires run between buildings are vulnerable to lightning. Only gas tubes are truly effective for this and do not load the signal much.If you, like me, wonder if these will work OK, here is my setup, which works fine at 100Mb:About 75 feet of direct burial cat 5e to an outbuilding. The cable has been in the ground for about 7 years but not previously used for Ethernet. There is a 66 block at each end. I tried unsuccessfully to put RJ45’s on the underground cable, but it was impossible, the wire is too large. I know 66 blocks are not supposed to be used for 100Mb but it works fine. A short cat5e cable runs to the arrestor. Be sure the DIN rail is well grounded.

Beware Radio OperatorsBeware Ham Radio Operators: Bought this for my Ham‘s PC Network to protect it from lightning or power surges finding their way to my Ethernet Switch. Since a ground wire was not included, I had to fabricate a special short wire to attach to the Ham station common ground (connects to the main house ground 8 feet away). Simple enough and installation was easy. Checked Internet speed with and without this device and saw no degradation 👍. When I got on the air, my digital mode transmissions went nuts. Somehow RF was finding its way into the item via the ground wire since disconnecting it solved the problem. So I wrapped three turns of the ground wire around a 1/2” ID ferrite clamp-on suppressor and reconnected the wire which solved the problem. Apparently this item has no internal RFI protection circuitry and is very susceptible to power in excess of 100 watts that is contained in coax and grounded equipment. This is a HUGE disappointment.

No ground wireWhether it performs as it should I don’t know yet, However my complaint is that it shows a ground wire option but they don’t send you the wire.Update: The description doesn’t explicitly say that the wire was included so my fault for assuming that it was.

Great valueOne surge protector unit was assembled incorrectly from the factory, but I only needed 8. No instructions come with it so it’s up to the user to figure out how to use the surge.

Lighting protection that works.We took a direct lightning strike which travelled 600’ through Ethernet cable before being shunted by the surge arrestor.The ubiquiti Nanobeam 3 feet away survived while the input Ethernet cable melted.
