Nader NDU series surge protector (SPD) is used to protect the surge caused by lightning or other transient overvoltage, discharge the surge current on the power line to the ground, and limit the overvoltage. It is applicable to the power supply protection of industrial, construction, civil aviation, finance, securities, telecommunications, ports and other systems. It suppresses the instantaneous overvoltage amplitude of lightning and operating overvoltage, discharges the surge energy, and protects the safety of system circuits and equipment. Among them, ndu1 surge protector can be installed in the area of lightning protection LPZ0B/LPZ1, which is used to protect the aerial lines in the distribution system with AC 50Hz / 60Hz rated working voltage of 220V / 380V from direct lightning without attenuation
