HLSA12,5-275/3+1 S

Article number: 10 039
  • Lightning impulse current and surge arresters type T1+T2+T3.
  • The products consist of varistors with big discharge ability.
  • HLSA12,5 in configurations 1+1, 3+1 and HLSA12,5G are additionally combined with a gas discharge tube which ensures zero leakage current through the PE conductor.
  • Suitable for objects with considerable levels of protection LPL III and LPL IV.
  • Installed at the boundaries of LPZ 0 – LPZ 1 and higher zones, closest to where overhead line enters the building i.e. in the main distribution boards.
  • In case of the installation of a type T1+T2+T3 in the main switchboard, it is also necessary to install type T2 and T3 in any additional distribution boards in the electrical installation.
  • 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.
