Lightning Arresters

Product Description

Our valued customers can avail from us SPC PV Lightning Arrester type 1+2, which is designed according to EN 61643-11. It is used for protection of positive and negative busbars of photovoltaic systems against the surge effects. Also, these are suitable for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-1 (according to IEC 1312-1and EN 62305).  In these surge arresters particular varistor sectors are connected between terminals L+, L- and PE, and are equipped with fitted internal disconnectors that activate when varistors fail (overheat). In case of overheat these arresters disconnect the main power and indicate a signal that is partly mechanical (by red signaling target) and partly remote monitoring (by potential free switching contacts).
