Features and benefits
FN 3287 and FN 3288 series of filters provides state-of-the-art EMI attenuation based on an innovativefilter topology. They help to ensure compliance withClass C2 or even C1 limits.The slim book-style shape allows a convenient andspace-saving installation next to inverters,converters or motor drives.The compact FN3287 and FN3288 filter from 10 to160A are designed for the most diverse applicationsworldwide, including machinery and machine tools.FN 3288 HV filters up to 160 A are applicable for 690VAC distribution networks.FN 3288IT and FN 3288HVIT filters up to 160 A meetthe special requirements for IT distributionnetworks.Low leakage current filter versions help to fulfilltough requirements (e.g. 0.1 mA) in respect ofleakage current limitation.
Typical applications
Three-phase variable speed drives and power drivesystems (PDS)Machine tool and machinery equipmentIT power distribution networks (FN 3288IT and FN3288 HVIT)General energy conversion devices (inverters,converters)Process automation equipmentThree-phase power suppliesLow-leakage current requirements
