HLSA25G-255/4+0

HLSA25G-255/4+0 (Hakel Ligtning Surge Arrester) of the „G-Line“ range is a lightning and surge arrester according to EN 61643-11:2012 (IEC 61643-11:2011). It consists of high energy double varistors for better discharge ability and a gas discharge tube connected in series, which ensures zero leakage current through the conductor. Its parameters enable usage in buildings with considerable levels of protection LPL I and LPL II, such as hospitals, banks, industrial and administration complexes, schools, shopping and sports centres or supermarkets. The device is to be installed on the interface of LPZ 0 – LPZ 1 and higher zones according to standard EN 62305:2011 (IEC 62305:2010), closest to where overhead line enters the building i.e. in the main distribution boards. The product has two PE terminals, which can not be used as a PE bridge.
