SCHAFFNER
3-phase+N EMC filter, FN3256-series
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.
Mainly industrial equipment, machinery, machine tools and diverse process auto- mation systems with three-phase and 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.
- 8-160 A
- 520 V AC
- Good attenuation performance
