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.
