PIIIM PV 400/M Vseries
Article number: 27 057- 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.
