Schaffner's FN3258 series are ultra-compact EMC/RFI filters for motor drives applications

Image of Schaffner's FN3258 Series 3-Phase FiltersSchaffner’s FN3258 series is one of the most efficient three-phase filters currently available on the market. The extremely compact, slim design allows a trouble-free installation even where the available mounting space is minimal. The case size and its effective performance has made the FN3258 series a very popular choice for inverters, converters, motor drives, and servo drives applications.

With new additional filter types providing safety terminal blocks, the most preferred connection style can be chosen quickly and easily. This helps to stay in line with the electrical connection concept of a given application.

The FN3258 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.

The 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.

Many of Schaffner's custom filters have been developed based on FN3258 core design for valued global customers. The FN3258 is a natural off-the-shelf choice for almost any three-phase application.
