FN 356
General purpose
three-phase and neutral line lter
Approvals
■
Three-phase and neutral line filter for
general four-wire filtering tasks
■
Choice of connection style
■
Low operating leakage current
■
Compliant with IEC 60950
■
Suitable to meet EN 55011/14/22
FN 356 up to 100A
Typical applications
■
FN 356 represents the industry standard
filter solutions for EMC compliance on
three-phases and the neutral conductor,
providing high attenuation of both sym-
metrical and asymmetrical interference.
■
Choice of connection style is offered for an
application-specific filter selection.
■
Solid touch-safe terminal blocks (-29, -33,
-34 versions) offer a generous contacting
cross section and contribute to overall
safety (IP20).
■
Used as a mains input filter, FN 356 filters
increase the conducted immunity and thus
contribute to system reliability.
■
Design compliance with IEC 60950
provides additional application
flexibility.
