HSA-275/3+1 M

HSA-275/3+1 M (Hakel Surge Arrester) of the „G-Line“ range is a surge arrester according to EN 61643-11:2012 (IEC 61643-11:2011) consisting of high energy varistors in combination with gas discharge tube, which ensures zero leakage current in the PE conductor. Its parameters enable its use in complex circumstances. The device is to be installed on the interface of LPZ 1 – LPZ 2 and higher zones according to standard EN 62305:2011 (IEC 62305:2010), i.e. into subsidiary switchboards and control boxes.
