Nader Circuit Breaker NDU Series Surge Protector NDU3 LPZ0B/LPZ1 AC 50/60Hz 220/380V

The NDU series surge protector (SPD) is used for the surge protection caused by lighting or other transient overvoltage, thus limiting the voltage by discharging the large surge current on the power line to the ground. It is suitable for power protection of the industry, construction, civil aviation, finance, security, telecommunication, port and other systems. It can suppress the instantaneous overvoltage amplitude for lighting and operation overvoltage, and discharge surge energy, thus protecting safety of the system circuit and equipment. The NDU3 surge protector can be installed in the LPZ0B/LPZ1 area with lightning protection for protecting the direct lightning that isn't attenuated with the overhead line in the power distribution system with the AC 50/60Hz and rated working voltage of 220/380V.
