Product Description:
The NFD03.1-480-055 is a passive mains filter produced by Bosch Rexroth Indramat for use in the NFD Mains Filters series. Installed between the incoming three-phase supply and drive controllers, the unit suppresses conducted electromagnetic interference so that surrounding equipment and fieldbus networks remain within legal emission limits. By attenuating high-frequency noise before it propagates onto plant power rails, the filter improves EMC compliance and helps reduce the chance of drive-related malfunctions in automated systems. Its position at the power entry point allows it to act on line-borne noise before that noise spreads through shared electrical distribution.
This model is rated for a continuous line current of 55 A, allowing it to serve medium-power inverter groups without excessive temperature rise. It connects to utility feeders up to AC 480 V +10%, so it accommodates common 400 V and 480 V industrial grids. The permitted supply frequency extends from 0 to 60 Hz, covering static converters as well as standard mains service. Designed for three-wire systems, it processes 3 phases simultaneously while maintaining balanced impedance on each conductor. Conducted noise is reduced across a spectrum of 0.15 to 30 MHz, a range that targets the switching harmonics commonly generated by modern IGBT-based drives.
During normal service, the filter dissipates only 25.9 W as heat, so cabinet ventilation requirements remain moderate. Its open-frame housing carries a protection rating of IP20, which means the unit must be mounted inside an enclosure to prevent accidental contact and limit exposure to contaminants. All components are specified to function between -25 to +85 °C, giving broad thermal tolerance for both cool machine rooms and warmer process areas. At a mass of just 2.0 kg, the device places little load on DIN rails or backplates. The low weight also supports placement close to connected drives, which helps keep conductor runs shorter and reduces the size of potential emission loops.
