SPC12,5 DS/2+0

SPC12,5 DS/2+0 is a metal oxid varistor lightning and surge arrester type 1+2 according to EN 61643-11 and IEC 61643-11. These 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 SPC12,5/2+0 is mainly in the power supply lines. The main use of SPC12,5/2+0 arrester is in structures of LPL III – IV according to EN 62305 ed.2.

Double terminals of the device allow the “V” connection at the maximum current-carrying capacity of 125A.
