Schaffner FN 258 Series — 3-Phase Filters | Book-style EMC/RFI Filter for Inverters and Power Drive Systems: FN 258 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, FN 258 are ready for the most diverse applications worldwide. FN 258 HV filters up to 130 A are designed for 690 VAC distribution networks. FN 258 HVIT filters up to 130 A meet the special requirements for the application in industrial 690 VAC IT distribution networks. FN 258 L and FN 258 P 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. Features: ? Industry standard EMC solution for three-phase PDS filtering ? Slim space-saving book-style housing ? Solid safety connector blocks or optional wire output connections ? Excellent attenuation performance ? HV versions for up to 690 VAC ? HVIT versions for IT distribution networks ? P/L versions with low leakage current Applications: ?
