Surge Protector Device Power Source Arrester Surge Protection Appliance AC 385V Surge Lightning Protective Device SPD

Product DescriptionGD-B series surge protector device(in short:SPD,alias:surge protector,surge arrester) is suitable for TN-S, TN-C-S, TT, IT etc. Power supply system of AC 50/60Hz,≤380V, ans installed on the joint of LPZOA zone or LPZOB and LPZ1 zone, which protects the electric network not shocked by the thunder, it's designed according to GB18802.1, IEC61643-1, it adopts 35mm standard rail, there is a failure release mounted on the module of surge protective device, when the SPD fails in breakdown for over-heat and over-current, the failure release will help electric device separate from the power system and give the indication signal,green means normal,red means abnormal, it's also could be replaced for module when has operating voltage.Intensity of Remote Signalling Alarm ContactFailure indication and centralized remote signalling alarm dry contacts;High discharge capacity and low residual voltage;Over-temperature protection;IP20, UL94 V0 Product Features GD-B series surge protective devices is suitable for B grade lightning proof, installed on the joint of LPZOA zone or LPZOB and LPZ1 zone, which protects the electric network not shocked by the thunder or surge over voltage. GDB-100,GDB-80,GDB-60  are usually in installed in low voltage main distribution box connected to the incoming end of the buliding. Product Parameters ModelGD-BRated Operating Voltage Un(V)220V      380V220V      380V220V      380VMaximum Continuous Operating Voltage Ue(V)385V      420V385V      420V385V      420VVoltage Protection Level Up(kV)≤2.8        ≤3.2≤2.2        ≤2.5≤2.0        ≤2.3Nominal Discharge Current In(8/20μs)kA604030Maximum  Discharge Current Imax(8/20μs)kA1008060Response Time ns
