The NFD02.2-480-016 is a mains filter manufactured by Bosch Rexroth Indramat. Especially designed to interact with the HCS product group of converters, this device operates optimally between 0Hz and 50Hz at 45°C, with a nominal voltage ranging from 115VAC to 480VAC. It possesses inductors that allow low frequency or DC currents to pass, while efficiently blocking harmful high-frequency currents. The device also minimizes any frequency signal beyond the filter's cut-off frequency. It is essential that it is properly grounded to avoid damage and should be used with shielded cables supplied by the manufacturer to ensure EMC limit compliance. The filter decreases interference in electronically controlled motors and dampens disturbances in connected cabling. It handles both asymmetrical and symmetrical interferences occurring within three-phase electronic units, with a leakage current of 175mA to 190mA at 50Hz during a single phase failure. Installation should be in close proximity to the device it protects, in an upright position, with the ground wire connected to a 10mm2 cross-section conductor via a ring cable plug or a plug connector. The NFD02.2-480-016 is equipped with IP 20 protection rating.
