Features and benefits
The extremely compact and slim filter design allows
a trouble-free installation even where the available
mounting space is minimal
With new additional filter types providing safety
terminal blocks, the most preferred connection style
can be chosen fast and easy. This helps to stay in
line with the electrical connection concept of a
given application
FN 3258 filters ensure compliance with Class A limits
according to EN 55011 up to 50 m cable length and
beyond. Further they can contribute significantly to
meet conducted emission limits according to Class
B
Filter operation on the mains input side of
consumers increases their reliability and conducted
immunity significant
Chokes with exceptional saturation resistance and
excellent thermal behavior are a vital part of FN 3258
design. Thus, all filters retain the expected filter
performance even in very noisy applications and
under full load conditions
Typical applications
Three-phase variable speed motor drives, servo
drives, inverters and converters
Applications comprising energy conversion devices
like machines or process automation equipment
HVAC equipment, elevators, power supplies, UPS
and further three-phase applications
