PIVM12,5-275/3+1 Vseries is a four-pole, metal oxide varistor lightning and surge arrester, combined with gas discharge tube Type 1+2 according to ICE EN 61643-11. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0 – 1 (according to IEC 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 PIVM12,5-275/3+1 Vseries is mainly in the power supply lines, which are operated as TN-S and TT systems. The main use of PIVM12,5-275/3+1 Vseries arrester is in structures of LPL III-IV according to IEC EN 62305. The marking M specifies a type of construction with a removable module. The marking of DS specifies a version with remote monitoring.
