DATASHEET 3-Phase Filters FN 3258 Ultra-compact EMC/RFI Filter for Motor Drives Applications New: solid safety connector blocks available for Approvals the whole range Exceptional attenuation performance from 150 kHz to 30 MHz Excellent saturation resistance up to 50 m cable length Most compact and slim filter design in its class 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 Technical specifications under full load conditions Design corresponding to UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939 Typical applications Flammability corresponding to UL 94 V-2 or better High potential test voltage P > E 2650 VDC for 2 sec Three-phase variable speed motor drives, servo P > P 2100 VDC for 2 sec drives, inverters and converters Maximum continuous operating voltage 3x 480/277 VAC (FN 3258) Applications comprising energy conversion devices 3x 520/300 VAC (FN 3258H) like machines or process automation equipment MTBF 50C/400V (Mil-HB-217F) 300,000 hours HVAC equipment, elevators, power supplies, UPS Operating frequency dc to 60 Hz and further three-phase applications Overload capability 4x rated current at switch on, 1.5x rated current for 1 minute, once per hour Typical electrical schematic Protection category IP20 Rated currents 7 to 180 A 50 C Temperature range (operation and storage) -25 C to +100 C (25/100/21)2 EMC/EMI Products Schaffner Group Datasheets 2014 Filter selection table Filter Rated current Typical drive Leakage current** Power loss Input/Output Weight 50 C (40C) power rating* 400 VAC/50 Hz 25 C / 50 Hz connections A kW mA W kg FN 3258-7-44 7 (7.7) 4 33.0 3.8 -44 0.5 FN 3258-16-44 16 (17.5) 7.5 33.0 6.1 -44 0.8 FN 3258-30-33 30 (32.9) 15 33.0 11.8 -33 1.2 FN 3258-42-33 42 (46.0) 22 33.0 15.7 -33 1.4 FN 3258-55-34 55 (60.2) 30 33.0 25.9 -34 2.0 FN 3258-75-34 75 (82.2) 37 33.0 32.2 -34 2.7 FN 3258-100-35 100 (109.5) 55 33.0 34.5 -35 4.3 FN 3258-130-35 130 (142.4) 75 33.0 43.1 -35 4.5 FN 3258-180-40 180 (197.1) 90 33.0 58.3 -40 6.0 FN 3258H-7-44 7 (7.7) 4 33.0 3.8 -44 0.5 FN 3258H-16-44 16 (17.5) 7.5 33.0 6.1 -44 0.8 FN 3258H-30-33 30 (32.9) 18.5 33.0 11.8 -33 1.2 FN 3258H-42-33 42 (46.0) 22 33.0 15.7 -33 1.4 FN 3258H-55-34 55 (60.2) 37 33.0 25.9 -34 2.0 FN 3258H-75-34 75 (82.2) 45 33.0 32.2 -34 2.7 FN 3258H-100-35 100 (109.5) 55 33.0 34.5 -35 4.3 FN 3258H-130-35 130 (142.4) 75 33.0 43.1 -35 4.5 FN 3258H-180-40 180 (197.1) 110 33.0 58.3 -40 6.0 * Calculated at rated current, 440 VAC (FN 3258)/480 VAC (FN 3258H) and cos phi = 0.8.
