Features and benefits
Compact general purpose
three-phase and neutral line EMC fi lter
FN 256 filters are designed specifically for
applications involving asymmetric loads,
ranging from industrial controls to medical
electronics systems. These typically involve
insufficiently filtered converters and
switch-mode power supplies on different
phases, causing current imbalance and
significant interference problems.
Employing single-stage filter circuits for
each phase and the neutral line, FN 256 fil-
ters provide high attenuation of both sym-
metrical and asymmetrical interference.

Three-phase and neutral line filter for
general purpose four-wire filtering
Compact space-saving design
Choice of connection style
Low operating leakage current
Used as a mains input filter, FN 256 filters
also increase conducted immunity and
thus contribute to overall system reliability.
Choice of connection style as well as filter
ratings in line with common fuse values
support a fast and easy application-specific
filter selection and deployment.
A light weight aluminium housing with a
small footprint ensures that the filters can
be easily accommodated on control panels
and in tight power cabinets.
