Product Description:
The NFD02.2-480-030 is a passive three-phase mains filter manufactured by Bosch Rexroth Indramat as part of the NFD Mains Filters series. It is installed ahead of servo drives, inverters, or power-supply modules to suppress radio-frequency noise, protect upstream equipment, and improve conducted electromagnetic compatibility on industrial automation lines. By inserting impedance across each line conductor, the filter reduces differential and common-mode disturbances that might otherwise propagate onto the plant mains. This helps limit interference between switching equipment and other devices connected to the same supply network.
Electrically, the filter is rated for AC 480 V +10% on a three-phase supply, which aligns with common North American motor distribution systems. Under continuous operation, it carries a rated mains current of 30 A, with internal inductive and capacitive elements matched to that load. Steady-state power dissipation is only 14 W, which helps keep thermal rise low and keeps cabinet airflow requirements modest. The housing has an IP10 rating, so the unit is finger-safe but still intended for installation inside an enclosure. Insulation integrity toward grounded conductors is verified at 2800 VDC for two seconds between line or neutral and protective earth. Because it is a passive filter, attenuation is provided without active control electronics or a separate power source.
Cable terminations accept rigid copper conductors up to 16 mm², while flexible wiring is supported at 10 mm² and matches AWG 6 strand size; the protective-earth connection must be at least 10 mm². During cyclic demand, the device tolerates an overload of 1.5 × IN for 1 min/h, allowing brief current surges without compromising attenuation performance. Dielectric spacing across phase paths is confirmed by a line-to-line withstand of 2125 VDC for two seconds. The filter weighs only 1.8 kg, which reduces mechanical load on the mounting panel and makes placement easier in compact enclosures.
