HSA-440 M S

Article number: 27 189
  • 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.
