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
