DATASHEET 3-Phase Filters FN 3258 Ultra-compact EMC/RFI Filter for Motor Drives Applications New: solid safety connector blocks available for Approvals & Compliances 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 Performance indicators 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 Technical specifications consumers increases their reliability and conducted immunity significant Chokes with exceptional saturation resistance and Maximum continuous operating voltage 3x 480/277 VAC (FN 3258) excellent thermal behavior are a vital part of FN 3x 520/300 VAC (FN 3258 H) 3258 design. Thus, all filters retain the expected filter Operating frequency DC to 60 Hz performance even in very noisy applications and Rated currents 7 to 180 A @ 50°C under full load conditions High potential test voltage P –> E 2650 / 2750 VDC for 2 sec (FN 3258 / FN 3258H) P –> P 2100 / 2250 VDC for 2 sec (FN 3258 / FN 3258H) Typical applications Protection category IP 20 Overload capability 1.5x rated current for 1 minute, once per hour Three-phase variable speed motor drives, servo 4x rated current at switch on, drives, inverters and converters Temperature range (operation and storage) -25°C to +100°C (25/100/21) Applications comprising energy conversion devices Flammability corresponding to UL 94 V-2 or better like machines or process automation equipment Design corresponding to UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939 HVAC equipment, elevators, power supplies, UPS MTBF @ 50°C/400 V (Mil-HB-217F) 300,000 hours and further three-phase applications Typical electrical schematic
