Product Description:
The NFD03.1-480-007 mains filter is produced by Bosch Rexroth Indramat as part of the NFD Mains Filters series. Designed for installation at the power entry of servo drives and inverters, the unit attenuates conducted electromagnetic interference, improving compatibility between drive equipment and the plant supply network. By connecting in series with the three-phase supply, it blocks high-frequency noise and returns a cleaner waveform to the grid, which helps neighboring automation devices meet electromagnetic emission limits and maintain signal integrity on sensitive control lines.
The filter is intended for supplies up to 480 V AC, matching common plant distributions. It is configured for 3 phases, so all three line conductors pass through the internal inductors and capacitors before reaching the drive. Continuous load current capability is 7 A, allowing it to protect small and medium power converters without saturation. Terminals marked ek accept conductors up to 6 mm², while the rk side is limited to 4 mm²; this split capacity supports heavier incoming cables and lighter outbound wiring toward the drive cabinet. With these ratings, the filter can be placed close to the drive or in a centralized panel with minimal voltage drop.
The enclosure measures 50 mm in width, 160 mm in height, and 90 mm in depth, enabling dense mounting on DIN rail or back plate when multiple filters are required. During operation, the core and damping network convert switching noise into heat amounting to 3.9 W, so only modest ventilation is needed to keep the internal temperature stable. The mass of 0.7 kg allows single-person handling and permits installation on lightweight sheet-metal doors without reinforcement. Clearances around the case should follow local guidelines to maintain airflow and to ensure that adjacent components remain within their own temperature limits.
