ATLINK 35 Decoupling inductor for protector power supply coordination

Proper protection against transient overvoltages requires good coordination between protectors. ATLINK series inductors produce decoupling between protectors when they are connected in parallel on the same line so that each one acts at the right moment, achieving the double objective of withstanding the lightning current and reducing the overvoltage to an acceptable level for the connected equipment.

  • One ATLINK device is needed for each phase and another for the neutral. When selecting them, the operating current of the line must be taken into account, since this current will flow continuously through the device.
  • Its coordination capability has been tested and certified using lightning wave 10/350 µs according to EN 61643-11.
  • Enables installation of protectors for different stages in the same place, since the inductor substitutes the necessary length of cable for protector coordination.
  • Robust connectors, suitable for all types of connection.
  • ATLINK devices have been tested in official, independent laboratories, verifying that the protectors are correctly coordinated.
