Power supply lightning protection module（type A）

Power supply lightning protection module（type A） Electric surge protector of low-voltage distribution system is design according to IEC standard.It has invalidation detection indication,standard modularization installation,changeable lightning protection module and powerful discharge capacity of lightning current.It’s appliable to the protection of buildings’ general supply system against lightning.With 35mm standard guide-way,this lightning arrester is very convenient to be maintained.It connects with the circuit in parallel and has no limit to the power of equipment fixed later. Technical Parameters List: Model HD-D380M40A HD-D380M20A Nominal working voltage Un 380V 380V Maximum continuous working voltage Uc 385V 385V Nominal discharge current In（8/20ms） 20KA 10KA Maximum discharging current Imax（8/20ms） 45KA 20KA Voltage protection level Up 1.6KV 1.2KV Dimension 72×66×90mm Response time Ta ≤25ns Operating temperature range Tup -40℃ to +70℃ Section of minimum installed conductor 6mm2Multi-folded wire Protection grade IP20 Sheathing material Flame retardant thermoplastic material Mode of connection Parallel connection Protection mode 4+0/3+1/2+0/1+1 Installation Method: Ground the null line repeatedly when Long-distance overhead incoming lines enter buildings. Plug the power phase line (L) and null line (N）into corresponding connector of the electric surge protector and make sure it's firm and reliable. Connect the ground terminal of arrester with the ground lead of lightning protection well (recommended earth resistance ≤4Ω). Suggested specification of the lead wire: no less than 6mm2, short and straight.
