Telecommunication Signal Network Surge Arresterr

POE-3

1.Application The POE Ethernet Surge Protector is designed for the protection of network devices powered by Category 5e Ethernet cables. It is suitable for installation at interfaces between Lightning Protection Zones (LPZ1-LPZ3), ensuring that network devices are safeguarded against damage caused by overvoltages and overcurrents resulting from lightning strikes and industrial interference. 2.Functional performance The POE Ethernet Surge Protector features two-level protection, including coarse and fine protection. It has characteristics such as high surge current capacity, low residual voltage, and small insertion loss. It is widely used for lightning protection of wireless bridge devices and is intended for indoor installation.
