FN3256H-120-35 - 

Combining high attenuation performance with low leakage current and an extremely compact, light-weight design with a cubic shape, requiring minimum mounting space the FN3256 offers performance according to the machine tool standard EN50370-1. As a mains input filter for 3-phases + neutral line, the FN3256 ensures the compliance with the new product family standard for machine tools in mainly industrial environments EN50370-1, its use will also increase the conducted immunity of the entire installation significantly. The FN3256 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. Designed for industrial equipment, machinery, machine tools and diverse process automation systems with 3-phase + neutral electricity supply. Further, these filters are suitable for power supplies, high-power office equipment and further applications, where efficient interference suppression on three-phases and the neutral line is required and where space is critical. Because of the very low leakage current, FN 3256 can even be used for some medical devices. Solid, touch-safe terminal blocks offering sufficient contacting cross section according to the EN60204-1 installation standard.
