PIIIM PV 600 DS Vseries

Article number: 27 061
  • Surge arresters type T2 intended for photovoltaic systems (PV).
  • Products are designed in a Y-type connection, which is resistant to earth faults of working conductors.
  • Particular varistor sectors, connected between the terminals L+, L- and PE are equipped with internal disconnectors, which are activated when the varistors fail (overheat) and they are able to interrupt the DC current.
  • Special construction of the internal disconnector allows installation without a back-up fuse.
  • They are installed in PV applications without an external LPS or with an external LPS, where the sufficient distance "s" is observed.
  • Suitable for all LPL levels.
  • Ensure the equipotential bonding of positive and negative busbars of PV systems and the elimination of transient overvoltage that originates during the atmospheric discharges or switching processes.
  • M indication specifies a type of construction with removable module.
  • DS indication specifies a version with remote monitoring.
