RJ45 Lightning Protection for Gigabit 10/100/1000 (GbE) and High PoE++ Networks
The gigabit surge protector data 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 TP302 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. TP302 supports PoE++, also known as High Poe (IEEE 802.3bt standard), and allows a maximum PoE current of 154W/48V when used on all 4 pairs.
Installation
The Ethernet lightning arrestor must be properly grounded to work. The ethernet ground wire (12 Inch - 16 AWG) on the surge protector needs to be connected to ground 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, grounding rod or terminal of the closest outlet by connecting the ground wire to circular grounding hole on the grounded outlet center screw.
The lightning arrestor can be used with unshielded twisted pair (UTP) or shielded (STP) cables. The arrester is housed in a cast aluminum enclosure. The metal housing allows shielded current to be passed through the metal case of the network surge protector.
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 20KA 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.
Ethernet Surge Protector
Investing in a small, easy to install surge protector 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.

- PoE Mode Support Mode A and B for Power
- Protection Modes Line-Line, Line-Ground
- Tested standards IEC 61643-21, IEC61000-4-5
- Clamping Voltage Line-Ground: 72 Volts
- Clamping Voltage Line-Line: 72 Volts

I can't speak directly to the lighning protection as I'm not sure how I'd know, but I can say this is well built AND isn't just gigabit. Between my 2.5g capable switch and PC I'm getting full speed per iperf tests. Very excited that I'm not giving up those speeds, though I'm not sure if it will reduce maximum cable runs or whatnot.

Since they are grounded but installed in a plastic cabinet, I also purchased a plug-in grounding wire that they are both now attached to. They seem well built.

After a recent surge over our ethernet network from a nearby lightning strike, I decided to add these to the incoming lines from all the outdoor cameras. The cameras are POE and the protector allows them to work properly after being installed. I haven't seen any issues with the cameras going offline or degrading their throughput. I also tested these on a 500 mbps ethernet connection to my PC and an internet speed test showed that with the protector installed my device was still able to achieve the full speed provided by my ISP. I hope they function well if we encounter another nearby lightning surge in the future. We lost a lot of connected equipment prior to installing these. When installing, I made sure these all had a direct connection to our outside ground rod where the incoming cable TV line is also grounded to help dissipate any future surges.

An unusual, late February line of severe thunderstorms rolled through central, lower Michigan a couple of days ago.Two very close cloud to ground lightning strikes made the land line phone's bell ring twice. The next day, I noticed there was no network to the distant building. I bypassed the suspected surge protector with a cable coupler to determine if it was the problem, witch it was.All the other, expensive, network equipment was spared of any damage, so I'm buying two more as replacements.Very happy, highly recommended!

Very easy to install and connect. Did not slow our speeds down at all. Saved us for a third very costly replacement due to lightning strike. Very convenient size. We have several networks and I have put one on every line coming to save us money in the future. Great value I’d say. Already saved me money!

Great in line protection. It doesn’t impact performance. My only concern is that there is no way to know if it provides protection, until it doesn’t!

You need a surge suppression device when running copper ethernet between two buildings. These have sacrificial gas discharge tubes inside to suppress high voltage transients. You'll never know if or when surge suppression worked properly, you'll only know when it didn't. Seems like cheap insurance to me.One note, do not use two of these together (one at each end if you're running shielded cable. This will create a ground loop if the buildings are bonded. Worse it will be the sole ground path between them if they are not. I chose unshielded cable and decided to only use on suppressor near the switch for my install.

Benutze die Geräte sowohl um die DSL-Leitung ins Haus hinein abzusichern als auch um Netzwerk in den Außenbereich (IP-Cam) gegen Überspannungen zu schützen. Beides funktioniert ohne Mangel. Dei Geräte machen einen soliden Eindruck. Wie bei allen Blitzschutz-System hofft man das man Sie niemals brauch und das sie am Tag X dann auch gut funktionieren.
