Type 2 - Class 2 - 40kA - 1050VDC
The T2PV2/40/1000 and the T2PV2/40/1000R (Remote Version) are type 2 lightning & surge arresters according to EN 61643-11 and IEC 61643-11. This arrester is recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 1-2 (according to IEC EN 62305) for equipotential bonding of positive and negative busbars of photovoltaic systems and the elimination of transient overvoltages that originates during the atmospheric discharges or switching processes.
Particular varistor sectors, connected between the terminals L+, L- and PE, are equipped with internal disconnectors, which are activated when the varistors fail (overheat). The unit has a Status Indicator, showing green - ok / red - failure.
