FN 3256

Features and benefits

• An extremely 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
• Simple and time-saving installation with good accessibility for automatic and hand tools
• Solid, touch-safe terminal blocks 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 3256 ensures the compliance with the new product family standard for machine tools in mainly industrial environments EN 50370-1. Further, its use will also increase the conducted immunity of the entire installation significantly
• FN 3256 provides the attenuation performance to meet the requirements of various machine tools with up to 8 driving axes with ~10 m of motor cable each
• For easy selection and application, the filter current ratings are aligned with common fuse values

FN 3280

Features and benefits

• Now available up to 600 A
• Compact, space-saving design, optimized for industrial machinery
• Combines exceptional attenuation with low leakage current 
• Suitable for machine in mixed/ domestic environments ( Class A/B) 
• Increases also the immunity if operated directly on the mains input
• 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
• 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 needed to meet the requirements of various machine tools with up to 12 driving axes and ~10 to 20 m of motor cable each
• For easy selection and application, the filter current ratings are aligned with common fuse values

FN 354

Features and benefits

• The FN 354 family of filters is intended primarily for applications that require extremely effective interference suppression across a broad frequency spectrum.
• Advanced two-stage filter circuits with highly saturating resistant toroidal inductors, in conjunction with feedthrough capacitors on each of the three phases and the neutral line, ensure that these filters provide very high attenuation in the upper frequency band.
• FN 354 are equally suitable for the operation on star and delta power networks.

FN 355

Features and benefits

• The FN 355 family of three-phase and neutral line filters provides a cost-effective interference suppression solution for a wide variety of applications
• Available in four versions, with current ratings from 3 to 20 A, the filters employ a single-stage four-wire LC circuit with saturating resistant chokes, and have a very low operational leakage current FN 355 filters are contained within an extremely compact metal housing, making them ideal for use in situations where space is at a premium
