PIIIM PV 800/M Vseries

Article number: 27 068
  • Removable modules for surge arresters type T2 intended for photovoltaic systems (PV).
  • Contain a varistor with high discharge ability.
  • Modules 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.
  • 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.
