Complete photovoltaic block V25, 900 V DC

Combination arrestor, Type 1+2, for photovoltaic systems

• Error-resistant Y circuit for use according to VDE 0100-712 (IEC 60364-7-712)
• For surge voltage protection equipotential bonding to VDE 0100-443 (IEC 60364-4-44)
• Arresting capacity to 7 kA (10/350) and 50 kA (8/20) per pole

• Low DC protection level: < 3.0 kV and Voc max = 900 V DC
• arrestor, connectable with thermodynamic cut-off unit and visual function display
• Encapsulated, non-extinguishing zinc oxide varistor arrestor for use in distributor housings

Application: PV systems with or without separated insulated lightning protection system
