DACN1-35VGS-40-440 Type 1+2+3 AC surge protector - 4 pole is connected in parallel on the AC network and must be equipped with external fuses for short-circuit current protection

  • The total length of parallel connection wires to AC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
  • Wiring is made by screw connections. 
  • The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
  • The cross sectional wire must be 6 mm² minimum for Type 2 SPD and 16 mm² for Type 1.
  • Local earthing resistance must be in compliance with the electrical rules.
