DS40VG series Type 2+3 AC surge protector

DS40VG Type 2 +3 AC surge protector, using CITEL's 'VG technology', to completely eliminate the leakAge and operation current while providing maximum discharge capacity and an optimized level of protection.

The electric scheme includes a disconnector and its associated indicator.

The DS40VG surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase or 3-phase+N AC networks.

DS44VG-230 Type 2+3 AC surge protector - 3-phase+N are 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. On some models, a distribution bus can be used.
  • 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.

Further information can be found in IEC 61643-12 standard (selection and application principles for low voltage SPD).
