Features and benefits

■

General purpose EMC ﬁ lter

for three-phase applications

Broad range of power ratings for fast and

convenient filter selection.

Available as 440VAC (FN 351) and 520VAC

(FN 351H) versions for network-specific

applications.

FN 351 filters provide a broadband

common and differential-mode attenuation

performance, which remains available also

when high interference levels are present.

■

EMC solution for industrial inverters and

motor drives

Rated currents from 8 to 280A

Selectable voltage level of 440V and 520V

High differential and common-mode

attenuation

Compliant with IEC 60950

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.

... Calculated at rated current, 400VAC (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 400V, FN 351H at 480V). Note: if two phases are interrupted, worst case leakage could reach 6 times higher levels. ...
