Ethernet Surge Protector (10 pack) - PoE+ - Gigabit - (with DIN Rail Mount Option)
Ethernet Surge Protector (Pack of 10)
Model Number: TP309x10
An Ethernet Surge Protector (Pack of 10) is a surge protection device (SPD) that is inserted inline on an RJ45 CAT6/CAT5/CAT5e cable to prevent damage of electronic networking equipment. It can be mounted on the DIN Rail or used standalone.
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 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.
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 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.
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.
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.
