Features and benefits
FN 258 range of filters provides state-of- the-art EMIattenuation based on an innovative multi-stagefilter topology. They help to ensure compliance withClass A or even Class B limitsThe slim book-style shape allows a convenient andspace-saving installation next to inverters andmotor drivesWith 480 VAC rating and filter modules from 7 to250 A, FN 258 are ready for the most diverseapplications worldwideFN 258 HV filters up to 130 A are designed for 690VAC distribution networksFN 258 HVIT filters up to 130 A meet the specialrequirements for the application in industrial 690VAC IT distribution networksFN 258 L and FN 258 P filters help to fulfill toughrequirements in respect of leakage currentlimitation and provide an excellent solution toovercome problems with nuisance tripping ofsensitive earth leakage detectors
Typical applications
Three-phase variable speed drives and power drivesystems (PDS)IT power distribution networks (FN 258 HVIT)Applications comprising energy conversion devices(inverters, converters)Process automation equipmentThree-phase power supplies and UPSApplications with low-leakage current requirements(FN 258 L and FN 258 P)
