LIGHTNING ARRESTER TYPE 1+2
PHOTOVOLTAIC PROTECTION
a lightning arrester type 1+2 photovoltaic surge protector designed to be connected to the positive and negative busbars of photovoltaic systems to protect panels and inverters against surge effects
The WSP-T1PV2/12.5/1000R is a lightning arrester type 1+2 according to EN 61643-11. This photovoltaic surge protector is designed to be connected to the positive and negative busbars of photovoltaic systems to protect panels and inverters against surge effects.
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). Particular varistor sectors connected between terminals L+, L- and PE are equipped with fitted internal disconnectors which are activated when varistors fail (overheat).
Failure indication is both mechanical (by red pop-out flags) and via remote monitoring (by potential free switching contacts)
