Features and benefits

  • FN258 range of filters provides state-of- the-art EMI attenuation based on an innovative multi-stage filter topology. They help to ensure compliance with Class A or even Class B limits
  • The slim book-style shape allows a convenient and space-saving installation next to inverters and motor drives
  • With 480 VAC rating and filter modules from 7 to 250 A, FN258 are ready for the most diverse applications worldwide
  • FN258HV filters up to 130 A are designed for 690 VAC distribution networks
  • FN258HVIT filters up to 130 A meet the special requirements for the application in industrial 690 VAC IT distribution networks
  • FN258L and FN258P filters help to fulfill tough requirements in respect of leakage current limitation and provide an excellent solution to overcome problems with nuisance tripping of sensitive earth leakage detectors

Typical applications

  • Three-phase variable speed drives and power drive systems (PDS)
  • IT power distribution networks (FN258HVIT)
  • Applications comprising energy conversion devices (inverters, converters)
  • Process automation equipment
  • Three-phase power supplies and UPS
  • Applications with low-leakage current requirements (FN258L and FN258P)
