Rapidly changing thundering currents induce high voltages on electrical loops and twin-wires that can damage the insulation of the system. Various operations of the power system can generate operating overvoltage on the power cable.Some electrical equipment switching operations and short circuit trips can generate overvoltage (surge voltage) higher than the normal working voltage in the power cable, thereby causing damage to the electrical equipment.
Port connection mode:RJ45 Port
Nominal voltage:5V
Maximum continuous operating voltage UC:8V
Nominal discharge current IN:5KA
Protection level UP:≤45V
Data transmission rate VS:100Mbps
Operating temperature range:-40℃~+70℃
The rectangle size:65 x 25 x 25 mm
The Ground Cable Length: 160mm
Grounding: directly grounded by connecting wires
Network Surge Protector has a lower limiting voltage to protect against damage from inductive thundering strikes or other surges and overvoltages to protected equipment.
How I installed the ST-RJ45:
1.The input of Network Surge Protector is connected to the external signal cable.
2.The output of the Network Surge Protector is connected to the signal input of the protected device.
3.Connect the green ground wire to the ground. Note:
Please install surge protector within 1 meter from device protected.
Supports Ethernet card, Repeater, HUB, Switchboard, Router or other Ethernet devices.

Dropped my download speed by half based on Fast.com on Vermontel fiber to the home.Download speed dropped from 90 Mbps to 40. Many websites would not load.Installed at the box on the side of the house and grounded.

Easy and straight forward to install. Didn't take long to get it installed and it works perfectly.

Had this connected for a couple weeks. Connected to a small PoE PTZ camera on a tower. Tower is grounded and bonded and all coax on the tower is ran to lighten arrestors at the base. Camera randomly stopped working on a clear/sunny day. Opened the enclosure that this arrestor was in and the PoE cable was smoking at the connector on the camera output side of the arrestor. Glad I was able to catch it as it shorted and hopefully nothing else is damaged once I replace it with something of better quality. Would not recommend. Potential fire hazard if you aren’t there when it shorts out.
