Ethernet Surge Protector is a surge protection device (SPD) that is inserted inline on an RJ45 CAT6/CAT5/CAT5e cable to prevent damage of electronic networking equipment.

Powerful surges that the device protects against include direct lightning strikes, voltage spikes, or PoE overvoltages. Despite the primary protection (a direct strike to a line), the thunder arrestor also offers secondary protection, which will arrest EMF induced surges (nearby lightning).

Ethernet Surge Suppressor TP302 use a Gas Discharge Tube (GDT) on all 4 pairs (8 wires). Gas discharge tubes dissipate the voltage transient through a contained plasma gas which harnesses excess voltage in the incoming power and releases it safely. It ensures the safety of a wide array of valuable components such as network hub, switch, router, modem, bridge, repeater, or any part of ISP (internet service provider) network or LAN system.

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 ethernet surge protector PoE supports both Mode A (Pins 1,2+ 3,6-) and B (7,8+ 4,5-) of the 802.3af standard for supplying DC power. 802.3af (PoE) can deliver up to 15.4 watts per port over Cat5 cables with 12.95W assured to be available at the powered device, while 802.3at (PoE+) can deliver up to 30 watts over network cables with 25.5 watts available to devices. For that reason, PoE Plus is also known as High PoE. Ethernet surge protector allows PoE injected into the LAN cable at a voltage up to 60 volts DC, and typically 48 VDC is used.

The unit’s 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.

The Ethernet lightning arrestor must be properly grounded to work. The ethernet ground wire (11 Inch - 12 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.

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 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.

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.

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.

QUESTIONS & ANSWERS

Ask a Question
  • Can this be used to protect a cordless phone from lightning surges?

    No, this has RJ45 connections for internet connection with Cat 6 cable from modem or router to computer. To protect your phone you need a surge protector with a RJ11 connections. RJ11 is smaller and less wires. If you have an APC for your computer, it usually has RJ11 connectors for phone on the side. If not order a surge protector with RJ11 connections for telephone.

  • Does this device provide a ground for a shielded cable and connector to drain the EMI/noise?

    Not 100% sure, but the modular plug area plus housing, is all metal. So if you had a shielded cable properly terminated with a metallic modular connector, then I would have to say "Yes". Same potential.

  • Will this protect surges from fiber optic metal bearing cable that kills your ONT/Router?

    This device only protects the 8 pins of the Ethernet cable. It should be installed between your fiber media converter and the router. Most residential fiber optic Internet services use a box mounted outside your house where the fiber (sometimes having steel to give it strength) gets coupled to a none metal carrying fiber cable that then goes into your home. Based on the limited information your question contained, this is the best answer I can give you.

  • How do i determine which end is the protected equipment end. there are no markings that i can see on the ones i received.

    It simply won't let a 'spike' or sudden surge go THROUGH it. When the spike reaches this location, it sucks the surge off to the earth ground (why it's so important to connect the ground lead to the best and shortest grounding point available. So placing it would simply depend on where you expect the surge to come from (usually the 'incoming' or point outside the premise). I noticed that several of these devices I purchased had very short Cat5 jumpers. I concluded that the expected point is right at the router, camera, or other source you are trying to protect.

  • I have shielded Ethernet cables. Does this device pass the shield through?

    I would say no The plugs are not shielded they are plastic, so they would not.

  • Does this product provide a grounded jack for shielded cable?

    I know this answer may be too late, but .... The shield is continuous through the protector, but it does not appear to connect to the ground wire when I measure with an ohmmeter.

  • Is this a one time protection or does it work continuously? We get a lot of lightning and I want a continuously protective product.

    It works continuously. I've had one working for years through a lot of lightning storms.

  • What is the input and what is the output? No instructions or diagrams and the protector says nothing.

    Doesn't seem to matter.

  • Does this device come with an RJ45 patch cable?

    No.

  • Do you currently have the product: ethernet suge protector poe +gigabit 1000mlmbs?

    Yes works well, no slow down in speed that I can tell, but until I get a lightning strike I won't know if it works, I have it grounded into the UPS which powers the Poe switch.

  • Can this product be wall-mounted?

    Unfortunately, there is no direct way to wall mount, but since the cross-section is ~1" x 1" it is quite easy to fabricate a wall holder (e.g. cable clamp or tabbed cable tie).

  • I'm not an electrician. How do we attach the grounding wire?

    Attach it to the screw that holds the plate on your AC outlet, alternatively you can attach it to a screw on the back of your PC computer IF you are sure it's plugged into a grounded outlet.

  • Do they have to be grounded to work?

    Yes, they must have a good ground to work properly.

  • I have a powered antenna connected to my router with an ethernet cable. Will it pass enough power through to operate my antenna?

    I wasn't able to get it to work with a Poe wireless bridge. But our network eng was setting up a vlan at the same time and we were having problems with that.

  • My internet coming into my home has fried my router a couple of time; would this fix that?

    It will only help with static discharge travelling in the data line. Make sure router power supply is plugged into a surge protector too.

  • How do you know when it stops working?

    There no absolute certain way without test equipment that is not normally available. However, if the unit fails, the solid state voltage sensitive devices either fail to a shorted state, or the blow open and thus provide no further protection. The shorted failure mode is easy to detect. The device it is connected to stops working. Unplug the old Surge Protector substitute a new one, if the connected circuit starts to work, the surge supressor had failed. It is beyond the. Scope of the question to design and build a test jig that would provide a variable voltage to test whether the solid state voltage sensitive devices are still operational, but such a test circuit is the only way to really prove that a surge supressor is still operational. In my experience 70 to 80 % of the devices fail in the shorted state and as such, are detectable and should be replaced.

  • I have 12 solar inverters that are linked via ethernet. both in and out. shall i install two at each inverter and one at the house with the gateway?

    Not sure I understand the configuration described. My use case is to have one of the surge protectors on each end of a buried Ethernet cable I have running between two buildings. I have each surge protector attached to the electrical ground.

  • How did you ground this?

    Easiest way is to attach it to ground terminal of an outlet.

  • Will these operate with Cisco PoE switches at 56V?

    I don't know about the voltage, if you can get me the serial number of the POE switch to see if this voltage is different than the other Cisco POE switches that Cisco offers. If 56V is what all Cisco operate at.

  • I want to run this from my house to a shed. Do I need to place one on both ends as both ends connect to a switch?

    Yes, one at each end. The surge protectors will also need proper grounding. I would also recommend shield cable between the buildings. I have the same situation between buildings and would have aeqipment damage during T-Storms. This installation with these surge protectors has been trouble free for two years now!

  • How do these surpressors peform with network poe video cameras? any image distortion or degredation?

    They will not impact the signal at all. I have several of these on POE Ethernet cameras.

  • Description says it protect for wires of the cat5 cable. Can someone open it then share a picture of the internal components. Thanks.

    So you are asking someone to disable there unit and void their warmth for you, seems selfish and a bit bold to me.

  • Does this cause a slowdown in network speed?

    No, it has no effect on speed.

  • Wouldn't this ground wire to your outlet just send spike voltage to your electrical panel where all white neutral wires connect to all ground wires?

    Exactly. The ground bus in your panel is connected directly to an earth ground, which is where you want excess electricity to go.

  • Does this protect and handle POE+ as well?

    Yes. I use it with POE 100% of the time. I've used about 50 of these with redline Wimax (48v 1.5amps). It says POE right in the title...

  • Weatherproof/outdoor rated?

    Likely not outdoor rated, but the container would be weather "resistant" however as Allan comments, the connectors are not weatherproof or waterproof or even "resistant." If it is used outside, it will need to be put into a weatherproof container.

  • Can somebody please tell me how this device protects against thunder?

    Doesn't protect against Thunder, what it does do is dampen electrical surges on the Ethernet cable caused by lightning, thereby protecting the connected equipment. It will not protect against a DIRECT lightning strike to your house, nothing will. But it does protect against transient surges. Hope this helps.
