DATASHEET 3-Phase Filters FN 3258 Ultra-compact EMC/RFI Filter for Motor Drives Applications New: solid safety connector blocks available for the whole range Approvals 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 Performance indicators 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 Technical specifications Maximum continuous operating voltage 3x 480/277 VAC (FN 3258) 3x 520/300 VAC (FN 3258 H) Operating frequency Rated currents High potential test voltage DC to 60 Hz Protection category Overload capability IP 20 Temperature range (operation and storage) Flammability corresponding to Design corresponding to MTBF @ 50C/400 V (Mil-HB-217F) -25C to +100C (25/100/21) 7 to 180 A @ 50C P -> E 2650 / 2750 VDC for 2 sec (FN 3258 / FN 3258H) P -> P 2100 / 2250 VDC for 2 sec (FN 3258 / FN 3258H) 1.5x rated current for 1 minute, once per hour 4x rated current at switch on, UL 94 V-2 or better UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939 300,000 hours 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 under full load conditions Typical applications Three-phase variable speed motor drives, servo drives, inverters and converters Applications comprising energy conversion devices like machines or process automation equipment HVAC equipment, elevators, power supplies, UPS and further three-phase applications Typical electrical schematic 2 EMC/EMI Products Schaffner Group Datasheets 11 Oct 2018 Filter selection table Filter FN 3258-7-44 Typical drive Leakage current** Power loss Input/Output power rating* @ 480/520 VAC/50 Hz @ 25C/50 Hz connections [kW] [mA] [W] Rated current @ 50C (40C) [A] Weight [kg] 7 (7.7) 4 4.3 3.8 -44 0.5 FN 3258-16-44 16 (17.5) 7.5 4.3 6.1 -44 0.8 FN 3258-30-33 30 (32.9) 15 4.3 11.8 -33 1.2 FN 3258-42-33 42 (46.0) 22 4.3 15.7 -33 1.4 FN 3258-55-34 55 (60.2) 30 4.3 25.9 -34 2.0 FN 3258-75-34 75 (82.2) 37 4.3 32.2 -34 2.7 FN 3258-100-35 100 (109.5) 55 4.3 34.5 -35 4.3 FN 3258-130-35 130 (142.4) 75 4.3 43.1 -35 4.5 FN 3258-180-40 180 (197.1) 90 4.3 58.3 -40 6.0 FN 3258 H-7-44 7 (7.7) 4 4.7 3.8 -44 0.5 FN 3258 H-16-44 16 (17.5) 7.5 4.7 6.1 -44 0.8 FN 3258 H-30-33 30 (32.9) 18.5 4.7 11.8 -33 1.2 FN 3258 H-42-33 42 (46.0) 22 4.7 15.7 -33 1.4 FN 3258 H-55-34 55 (60.2) 37 4.7 25.9 -34 2.0 FN 3258 H-75-34 75 (82.2) 45 4.7 32.2 -34 2.7 FN 3258 H-100-35 100 (109.5) 55 4.7 34.5 -35 4.3 FN 3258 H-130-35 130 (142.4) 75 4.7 43.1 -35 4.5 FN 3258 H-180-40 180 (197.1) 110 4.7 58.3 -40 6.0 * Calculated at rated current, 440 VAC (FN 3258)/480 VAC (FN 3258 H) and cos phi=0.8.
