currents up to 2500A
n HV versions designed for 690VAC IT
power networks
n Busbars for convenient and universal
electrical connection
n Protective plastic covers optionally
available for unsurpassed safety
(600VAC)
Typical applications
n High-power filter for Class A compliance.
With approval measurement also Class B
compliance possible for some applications.
n Extremely compact high-current filter
solution with minimum space require-
ment.
n FN 3359HV versions for 690VAC are also
designed for use in IT power networks.
n All filters 320A and above are suitable for
regenerative motor drive system (with a
suitable line reactor).
n Optionally available transparent protective
covers for all filters up to 1000A, to protect
the installer, operator or inspector from
undeliberate touching of life conductors.
They can easily be retrofitted even if the
filter is already installed and connected.
n FN 3359 also improves conducted
immunity of installations.
n High-power motor drives, inverters and
converters
n Industrial three-phase systems
n Entire factories, plants and installations
n Large UPS
n Machinery
n Mining equipment
n Photovoltaic systems with galvanic
isolation*
n Wind turbines

* Calculated at rated current, 480VAC (FN 3359) / 690VAC (FN 3359HV) and cos phi = 0.8. The exact value depends upon the efficiency of the drive, the motor and the entire application.
** Maximum leakage under normal operating conditions. Note: if two phases are interrupted, worst case leakage could be much higher than the value shown.
