Surge protection device for LAN / Ethernet, lightning and surge protector, in hermetic box, BOX PTU-51-EXT/PoE, manufacturer

BOX PTU-51-EXT/PoE is designed to protect routers, LAN switches, IP cameras, WiFi access points against lightning and overvoltage. It is designed for external 100Mbit Ethernet (100Base-T) installations. It has 4-5kA @ 8 / 20μS protection efficiency for each conductor of a LAN cable (depending on their thickness). It protects devices installed on poles or metal constructions against the effects of lightning, overvoltages, tampering and against the effect of ground loops. It effectively eliminates overvoltages induced inside transmission pairs and between PoE supply pairs and discharges high-value surge currents to the ground. The built-in MOSFET fuse increases the efficiency of surge protection and eliminates potentials between CCTV installation earth points.

It is placed in hermetic external casing with sealing glands. Used LSA connectors on the Protected and Unprotected side have greater resistance to surge currents than RJ-45 sockets. The small size allows its use in installations where there is very little space - for example, installation inside lighting poles.

The product can be used for UTP and FTP cables of 5th, 5e, 6th and 6a categories but in any case the transmission speed will not be higher than 100Mbit.

It is perfect for protecting overhead LAN lines, which are exposed to high values of induced voltages in conductors and to high surge currents that can penetrate from metal structures, poles, masts, etc.

It can be used with other Ewimar PRO or EXT series protections if the LAN cable is only partly outside the building. To ensure full protection of the line located mainly outside, it is recommended to use products BOX PTU-51-EXT/PoE - one at each end of the cable. This allows you to more effectively protect connected devices, regardless of where the electric charge penetrates.
