AT-8463 ATLINK 63 : lines with I N≤ 63A
A proper protection against transient overvoltages needs a good coordination between SPDs. ATLINK 63 inductors provide decoupling between SPDs when they are connected in parallel at a same line. Thus, each one acts at the right moment, achieving the double objective: withstanding the lightning current and reducing the overvoltage to an acceptable level for the connected equipment.
One ATLINK is needed for each line and another for neutral. For their selection the line working current 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 10/350μs according to EN 61643-11.
-
Allows the installation of SPDs of different classes in the same place, since the inductor substitutes the necessary length of cable for SPD coordination.
- Robust connectors, suitable for all kind of connections.
ATLINK devices have been tested in offi cial, independent laboratories, verifying their working for a proper SPD coordinatio
ATLINK inductors are to be installed in series with the LV power supply line, that is, cutting the line and connecting the obtained cable ends to the input
and output connectors of the ATLINK. One ATLINK is needed for each line and another one for the neutral. There is no ground connection.
The power should be disconnected during the installation of the SPD. Coordinates mainly ATSHOCK and ATSHIELD with ATSUB and/or ATCOVER surge protective devices when they cannot be separated by a cable at least 10 meters long
