SPC PV-800 DS Lightning Arresters

SPC PV is a type 1+2 lightning arrester as per the EN 61643-1, which during surge effects can protect positive and negative busbars of photovoltaic systems. As per IEC 1312-1and EN 62305, SPC PV-800 DS Lightning Arrester can used in the Lightning Protection Zones Concept at the LPZ 0-1 boundaries. Varistor sectors connected between L+, L- and PE terminals equip fitted internal disconnectors which activate when varistors fail or overheat. Partly mechanical and partly remote monitoring are used to indicate the failure of the disconnectors.

Terminations 2-3 are open and 1-2 are connected to closed contacts when SPC PV-800 DS Lightning Arrester operates correctly. One can find out when its not working properly or its damaged due to  thermal overloading, when terminations 2-3 are closed and terminations 1-2 are open.
