Features and benefits

n The extremely compact and slim filter

design allows a trouble-free installation

even where the available mounting space

is minimal.

n 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

n Filter operation on the mains input side

of consumers increases their reliability and

conducted immunity significant.

n Chokes with exceptional saturation resist-

ance 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.

application.

n 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.

** Calculated at rated current, 440VAC (FN 3258)/480VAC (FN 3258H) and cos phi = 0.8. The exact value depends upon the efficiency of the drive, the motor and the entire application.

*** Maximum leakage under normal operating conditions. Note: if two phases are interrupted, worst case leakage could reach 5.4 times higher levels.
