3-Phase Filters with Neutral FN3280
High-end Line Filter for Machinery/Equipment
Now available up to 600 A
Approvals & Compliances
Compact, space-saving design, optimized for
industrial machinery
Combines exceptional attenuation with low
leakage current
Suitable for machines in mixed/domestic
environments (Class A/B)
Increases also the immunity if operated
directly on the mains input
Features and Benefits
A compact and light weight filter design with a
„cubic“ shape, requiring minimum mounting
space and thus taking the constructional
conditions on the mains input of machinery into
account
Performance indicators
Simple and time-saving installation with good
accessibility for automatic and hand tools
Solid, touch-safe terminal blocks (8 to 200 A
types) offering sufficient contacting cross section
according to the EN 60204-1 installation standard,
which is very common in industrial applications
As a mains input filter for three phases and
neutral line, FN 3280 provides enough
performance to ensure EMC compliance of
machinery in mixed (Class A) or even domestic
(Class B) environments. Further, its use will also
increase the immunity of the entire installation
significantly
FN 3280 provides the attenuation performance
needed to meet the requirements of various
machine tools with up to 12 driving axes and ~10
to 20 m of motor cable each
Technical Specifications

Temperature range (operation and storage)
-25°C to +100°C (25/100/21)
Flammability corresponding to
UL 94 V-2 or better
Design corresponding to
UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939
MTBF @ 50°C/400 V (Mil-HB-217F)
>360,000 hours
For easy selection and application, the filter
current ratings are aligned with common fuse
values
R69 option for easy compliance to IEC 60204-1
(DIN VDE 0113): Suitable for complex machines,
where the overall insulation resistance needs to
be higher than 1 MOhm.
Typical Applications
Mainly industrial equipment, machinery, machine
tools and diverse process auto- mation systems
with three-phase and neutral electricity supply.
Due to the outstanding attenuation performance,
FN 3280 is also the first choice for noisy power
supplies, renewable energy applications,
highpower office equipment and further threephase and neutral devices. Because of the
relatively low leakage current, FN 3280 may even
be used for some medical devices.
