Lightning Surge Protector

PIV850 is modular lightning arrester type 1 according to EN 61643-11. Complete device consist of a base part and pluggable module. 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) for lightning current equipotential bonding and elimination of switching surges that originate in power supply systems entering the building.
The PIV850 is mainly intended for use in TNC systems. For TNS and TT systems it is necessary to combine these arresters with lightning arrester B25 or B50 which are intended for equipotential bonding between N and PE.
The main use of PIV850 arrester is in structures of LPL III IV according to EN 62305, e.g. residential houses with cable supply and subdistribution boards of big industrial structures.
