Type 1 DC 3 Pole - T12PA-YDC-3-1000R

T1/2, DC Lightning & surge arrester for LPL III & IV

This series of lightning and surge arresters are type 1+2 according to EN 61643- 11, IEC 61643-11 and UTE C 61-740-51. They are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-2 (according to IEC EN 62305) for equipotential bonding of positive and negative busbars of photovoltaic systems and elimination of transient overvoltages originating from atmospheric discharges or switching processes. The varistor modules are connected between L+, L- and PE conductors and are equipped with internal disconnectors. Operational status indication of these disconnectors is both visual (the indication window changes to Red) and remote (by potential free, change over contacts). The varistor modules are replaceable and can be ordered separately as a service item.
