PIV12,5-275/4+0

PIV12,5-275/4+0 is a four-pole lightning and surge arrester Type 1+2 according to EN 61643-11 and IEC 61643-11. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0 – 1 (according to IEC 1312-1 and EN 62305), where they provide the equipotential bonding and discharge of both, the lightning current and the switching surge, which are generated in power supply systems entering the building. The use of the lightning current arresters PIV12,5-275/4+0 is mainly in the power supply lines, which are operated as TN-S system. The main use of PIV12,5-275/4+0 arrester is in structures of LPL III – IV according to EN 62305 ed.2.

The marking of DS specifies a version with remote monitoring.
