Surge arrester, 7P.03.8.255.Z012, Finder

Surge arrester, suitable for low-voltage installations, for protecting equipment against overvoltages caused by direct lightning strikes, induced overvoltages and switching overvoltages. SPD type 1 + 2 surge arresters for quick mounting on the busbar, for 3-phase low-voltage systems (230/400 V), without leakage current and without follow current. Including overcurrent protected 230 V power supply for APZ and RFZ according to DIN VDE AR-4100.
