HSA-275/3+0 M S (Surge Arrester) : TYPE 2+3, CLASS II+III , 3 Poles

HSA-275-3-0 M S
  • HSA-275/3+0 M S (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. 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.
  • Surge arresters type T2+T3 ensure the equipotential bonding and reduce switching, induced and residual overvoltage in LV power supply systems.
  • The products consist of varistors with big discharge ability.
  • Configurations 1+1 and 3+1 are additionally combined with a gas discharge tube which ensures zero leakage current through the PE conductor.
  • Installed at the boundaries of LPZ 1 – LPZ 3 into subsidiary switchboards and control panels.
  • If the product contains two PE (or PEN) terminals, it must not be used as a PE (PEN) bridge.
  • M indication specifies a type of construction with removable module.
  • S indication specifies a version with remote monitoring.
