The DS500E range of surge protectors are Type 1 + 2, very high power, they are intended to be installed at the entry of the Low Voltage installation. They are used to protect single-phase, three-phase or three-phase + Neutral networks in common mode or in common and differential mode. The 'Multi-Varistor' technology used allows the best possible behavior for the LV network (no follow-on current). The DS500E range is installed on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.

DS504E-320/G Type 1+2 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).
