Features and benefits
FN 3287 and FN 3288 series of filters provides state-
of-the-art EMI attenuation based on an innovative
filter topology. They help to ensure compliance with
Class C2 or even C1 limits.
The slim book-style shape allows a convenient and
space-saving installation next to inverters,
converters or motor drives.
The compact FN3287 and FN3288 filter from 10 to
160A are designed for the most diverse applications
worldwide, including machinery and machine tools.
FN 3288 HV filters up to 160 A are applicable for 690
VAC distribution networks.

Performance indicators
FN 3288IT and FN 3288HVIT filters up to 160 A meet
the special requirements for IT distribution
networks.
Low leakage current filter versions help to fulfill
tough requirements (<3.5 mA) in respect of leakage
current limitation.

* Additional filter versions with lower leakage currents (lower Cy capacitors) available -> replace Cxx with C25.
** Typical power rating (400 VAC for FN 3287 and FN 3288 / 690 VAC for FN 3288 HV and FN 3288 HVIT) with cos phi=0.85. The exact value depends upon the efficiency of the drive,
the motor and the entire application.
*** Standardized calculated leakage current acc. IEC 60939 under normal operating conditions (FN 3287, FN 3288 and FN 3288 IT at 480 VAC, FN 3288 HV and FN 3288 HVIT at 690
VAC).
****These filters may be operated in IT system as long as the operation conditions and possible short circuit/fault (earth connection of one conductor) occurs between the supply
(line side) and the filter. The filters are not designed for short circuit/faults occurring between converter and motor.
