HLA50-255/4+0

HLA50-440/4+0 of the „G-Line“ range is a lightning arrester according to standard EN 61643-11:2012 (IEC 61643-11:2011) consisting of multiple non-exhausting spark gaps. Its parameters enable usage in buildings with a considerable level of protection LPL I, such as big industrial complexes and properties of particular importance – hospitals, banks, power plants. The device is to be installed on the interface of LPZ 0 – LPZ 1 zones according to standard EN 62305:2011 (IEC 62305:2010), closest to where the overhead line enters the building i.e. the electric power substation, electrometer or the main distribution boards.The product has two PE terminals, which can not be used as a PE bridge.
