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 50m 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
