Type 1 DC 4 Pole - T12PA-UDC-1-1000R
T1/2, DC Lightning and surge arrester for LPL I and II
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).
