Product Description

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).
Gas discharge tubes (GDTs) are developed to overcome some of the disadvantages of diode-based protectors like energy handling capability and is suitable for almost all surge, whether high or low frequency, it can be intercepted by a gas discharge tube surge arrester so it provides a rigorous spark discharge control performance.
Ethernet Surge Suppressor TP309 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 switch, router, modem, bridge, repeater, or any part of internet service network.

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 , 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 ModeA (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 Ethernet lightning arrestor must be properly grounded to work. When used on the DIN Rail it is connected to the ground through the rail, and when used as standalone a ground wire needs to be connected from the surge protector to the 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 typiy 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.

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.


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.
