Features and benefits
FN 258 range of filters provides state-of- the-art EMI
attenuation based on an innovative multi-stage
filter topology. They help to ensure compliance with
Class A or even Class B limits
The slim book-style shape allows a convenient and
space-saving installation next to inverters and
motor drives
With 480 VAC rating and filter modules from 7 to
250 A, FN 258 are ready for the most diverse
applications worldwide

***To compile a complete part number, please replace the -.. with the required output connection style.
***Calculated at rated current, 440 VAC (FN 258)/690 VAC (FN 258 HV) 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 (FN 258 at 440 V, FN 258 HV at 690 V). Note: if two phases are interrupted, worst case leakage could reach 5.7 times
Note: typical attenuation performance of FN 258 standard filters. The behavior of FN 258 HV, FN 258 HVIT, FN 258 P and FN 258 L may be slightly different.
