HD-D220M20C

Series connection type power surge protector This product adopts ultra-fast conduction of large-capacity surge absorbing element "zinc oxide varistor" as the core component, with normal or failure indication function, and installed over-current thermal tripping mechanism, in case of failure can be automatically detached from the grid. Meets electrical safety standards. With a variety of shapes of power outlets, it is suitable for all electrical equipment that meets national standards. Model HD-D220M20C Nominal working voltage Un 220V Maximum continuous working voltage Uc 275V Nominal discharge current In（8/20μs） 10KA Maximum discharging current Imax（8/20μs） 20KA Voltage protection level Up ≤1.2KV Response time Ta ≤25ns Over-current protection 10A Fault indication Yes Protection grade IP40 External dimension 98*50*38mm Sheathing material Flame retardant thermoplastic material Mode of connection In Series Installation method： When the plug of the lightning protection socket is plugged into the mains jack, please make sure that the mains line is normal and the power line (L) and neutral line (N) have no errors.. You can connect the plug of the lightning protection socket to mains jack to ensure the reliability. When a long-distance overhead line enters a building, the neutral line is grounded repeatedly, and the grounded end of the connection socket or lightning protection ground wire is connected well. (Recommended grounding resistance ≤ 4Ω)
