Economical series surge arrester for Gigabit Ethernet 1000Base-T also compatible with 10Base-T and 100Base-T. It is designed for LAN devices installed inside of buildings. Eliminates surge currents up to 100A (8/20uS) inducted inside of cabling, generated by electromagnetic impulse during lightning. Very carefully designed multilayer PCB with special production process and modern components allowed to obtain the excellent parameters required in 6 category cabling.

Independent PoE protection circuits eliminate the voltage increase between pairs 1.2 - 3.6 and 4.5 - 7.8. This solution protects power supplies of LAN devices against damage due to overvoltage or unintentional voltage increase - for example as a result of damage to the PoE power supply. The solutions used are completely neutral for PoE regardless of the standard used, including Hi PoE.

PTF-61-ECO/PoE is designed for mounting near LAN endpoints such as: PCs, PLCs, IPC cameras, Wifi transmitters, IoT devices. It is equipped with a standalone enclosure with the possibility of mounting to the wall. For correct operation, it is necessary to properly ground the surge arrester with the PE line and preferably the shortest possible ground point. It is also necessary to observe the directional operation of the protective function described in the user manual and do not reverse the connections of the device in the LAN system, which may cause its malfunction or even damage.

 

Correct surge protection of 1000 Mbit LAN

Correct protection of a gigabit LAN using two pieces of the PTF-61

 

The PTF-61 can also be used on the LAN switch side, however, for many channels, we recommend the use of PTU-6xx or PF-6xx series multichannel surge arresters.
