3-Phase Filters with Neutral FN3256
DATA
SHEET
Compact Line Filter for Industrial Machinery/Equipment
Compact, space-saving design, optimized for
industrial machinery
Approvals & Compliances
Combines high attenuation performance
with low leakage current
Performance according to the machine tool
standard EN 50370-1
Increases also the immunity if operated
directly on the mains input
Features and Benefits
An extremely 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 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 3256 ensures the compliance with
the new product family standard for machine
tools in mainly industrial environments EN
50370-1. Further, its use will also increase the
conducted immunity of the entire installation
significantly
FN 3256 provides the attenuation performance to
meet the requirements of various machine tools
with up to 8 driving axes with ~10 m of motor
cable each
Technical Specifications
3x 520/300 VAC (480 VAC +10% possible)
DC to 60 Hz
Maximum continuous operating voltage
Operating frequency
For easy selection and application, the filter
current ratings are aligned with common fuse
values
8 to 160 A @ 50°C
Rated currents
P/N –> E 2750 VDC for 2 sec
P –> P 2250 VDC for 2 sec
P -> N 1300 VDC for 2 sec
High potential test voltage
Typical Applications
IP 20
Protection category
Overload capability
Mainly industrial equipment, machinery, machine
tools and diverse process auto- mation systems
with three-phase and neutral electricity supply.
Further, these filters are suitable for power
supplies, high-power office equipment and further
applications, where efficient interference
suppression on three phases and the neutral line is
required and where space is critical. Because of the
very low leakage current, FN 3256 can even be
used for some medical devices.
