800Vdc - T1PV2/12.5/800 & 800R

800Vdc - T1PV2/12.5/800 & 800R

Type 1 - Class 1 / Type 2 - Class 2 - 12.5kA - 800VDC

The T1PV2/12.5/800 & T1PV2/12.5/800R (Remote Version) are lightning arrester type 1+2 according to EN 61643-11. It is designed for protection of positive and negative busbars of photovoltaic systems against the surge effects.

These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-1 (according to IEC 1312-1and 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 buttons) and via remote monitoring (by potential free switching contacts).

Function of remote monitor terminals:

When the T1PV2/12.5/800R is operating correctly, terminals 1 and 2 are closed, 2 and 3 are open. If the internal varistor component is damaged as a result of thermal overloading, terminals 1 and 2 open and 2 and 3 close.
