PIVM12,5-275 Vseries

Article number: 16 046
  • Lightning impulse current and surge arresters type T1+T2 ensure the equipotential bonding, eliminate the effects of lightning current and reduce switching, induced and residual overvoltage in single-phase and three-phase 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.
  • 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.
  • M specifies a type of construction with removable module.
  • DS indication specifies a version with remote monitoring.
  • Other voltage levels can be produced on request.
