are present
Solid, touch-safe filter terminals contribute to overall
equipment safety and make the filters compliant
with IEC 60950
Introduced as one of the very first motor drive EMC
filters in the market, FN 351 has been widely
imitated and has success- fully proven its function
over more than 10 years

* To compile a complete part number, please replace the -.. with the required I/O connection style.
** Calculated at rated current, 400 VAC (FN 351)/480VAC (FN 351H) 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 351 at 400 V, FN 351H at 480 V).
Note: if two phases are interrupted, worst case leakage could reach 6 times higher levels.
