DATASHEET 3-Phase + Neutral Line Filters FN 3280 High-end Line Filter for Machinery/Equipment Now available up to 600 A Approvals & Compliances Compact, space-saving design, optimized for industrial machinery Combines exceptional attenuation with low leakage current Suitable for machines in mixed/domestic environments (Class A/B) Increases also the immunity if operated directly on the mains input Features and benefits A compact and light weight filter design with a cubic shape, requiring minimum mounting space and thus taking the constructional conditions on the mains input of machinery into account Performance indicators Simple and time-saving installation with good accessibility for automatic and hand tools Solid, touch-safe terminal blocks (8 to 200 A types) offering sufficient contacting cross section according to the EN 60204-1 installation standard, which is very common in industrial applications As a mains input filter for three phases and neutral line, FN 3280 provides enough performance to ensure EMC compliance of machinery in mixed (Class A) or even domestic (Class B) environments. Further, its use will also increase the immunity of the entire installation significantly FN 3280 provides the attenuation performance Technical specifications needed to meet the requirements of various machine tools with up to 12 driving axes and ~10 to Maximum continuous operating voltage 3x 520/300 VAC (480 VAC + 10% possible) 20 m of motor cable each Operating frequency DC to 60 Hz For easy selection and application, the filter current Rated currents 8 to 600 A 50C ratings are aligned with common fuse values High potential test voltage P/N > E 2750 VDC for 2 sec P > P 2250 VDC for 2 sec Typical applications P -> N 1300 VDC for 2 sec Protection category IP 20 (8 to 200 A types) Mainly industrial equipment, machinery, machine IP 00 (300 to 600 A types) tools and diverse process auto- mation systems with Overload capability 4x rated current at switch on, three-phase and neutral electricity supply. Due to the 1.5x rated current for 1 minute, once per hour outstanding attenuation performance, FN 3280 is also -25C to +100C (25/100/21) Temperature range (operation and storage) the first choice for noisy power supplies, renewable Flammability corresponding to UL 94 V-2 or better energy applications, highpower office equipment and further three-phase and neutral devices. Because Design corresponding to UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939 of the relatively low leakage current, FN 3280 may MTBF 50C/400 V (Mil-HB-217F) >360,000 hours even be used for some medical devices.
