AC SPD 4P 40-80KA / Surge Arrester / Protective Device Anti Petir

4Pole AC SPD 40-80KA / 380 ~ 420VAC Instalasi Tegangan Listrik 3 Phase ( 3L + N + PE ) AC SPD (Alternating Current Surge Protective Device) adalah perangkat yang dipasang untuk melindungi peralatan instalasi listrik arus Bolak Balik ( AC ) pada jaringan listrik PLN dari kerusakan / terbakar akibat surge lightning ( lonjakan listrik akibat sambaran petir mendadak) ataupun OverVoltage Surge ( voltase berlebihan yang mendadak ) yang masuk jaringan listrik PLN maupun dari inverter penghasil energi listrik arus bolak balik lainnya ( AC electricity Generator). cara kerja SPD (Surge protective Device) adalah Mengalihkan lonjakan arus liar tersebut ke bumi (earth). Technical Parameters SUP1-B80 AC SPD 40-80KA Rated Operating Voltage Un(V~) : 380V Maximum Continuous Operating Voltage Uc(V~) : 420V Voltage protection Level Up(V~)kV : 2.5 Nominal Discharge Current ln (8/20s) : 40 kA Maximum Discharge Current lmax(8/20s) : 80 kA Response Time (ns) : 25 nano seconds Test Standard : IEC61643.1, GB Operating Environment(centigrade) : -40~+85 Max Connection Line : 35mm2 hard wire/35mm2 strand wire copper line Recommended Connection Line : 16mm2 hard wire/25mm2 strand wire copper line Installation : Standard Rail 35mm Material of Outer Covering : Burning-proof Nylon FSP-A 4P AC SPD series surge protection device (in short SPD,alias:surge suppressor surge arrester)is suitable for TN-S, TN-C-S, TT, IT etc, power supply system of AC 50/60Hz, 380V , installed on the joint of LPZ1 or LPZ2 and LPZ3. It's designed according to IEC61643-1, GB18802.1, it adopts 35mm standard rail, there is a failure release mounted on the module of surge protection device, When the SPD fails in breakdown for over heat and over-current, the failure rlease will help electric equipments separate from the power supply system and give the indication signal, green means normal, red means abnormal.
