NFD03.1-480-055

The Bosch Rexroth Indramat NFD03.1-480-055 unit from the NFD Mains Filters series is engineered to safeguard three-phase HCS converters against line disturbances and capacitor leakage currents. This Bosch Rexroth filter accepts direct connection to the mains supply and delivers conditioned power to the downstream choke. With a Product type rating as a Line filter and a Compatibility specification for HCS converters, it ensures electromagnetic compliance and extended converter lifetime. Its robust IP20 enclosure facilitates vertical mounting inside protective cabinets and supports a maximum input voltage of 380 to 480 Volts AC.

Incorporating a nominal Rated current of 55 Amps, the NFD03.1-480-055 dissipates 25.9 Watts during normal operation while confining EMI across an effective attenuation range of 0.15 to 30 MHz. The compact footprint spans Height 220 millimeters, Width 90 millimeters, and Depth 105 millimeters, with a total Weight of 2 kilograms. It accommodates AWG 4 power cabling or 16 mm² flexible and 25 mm² rigid conductors, supporting motor leads up to 75 meters. The filter endures ambient temperatures from –25 to 85 °C at up to 45 °C operating point and withstands a test withstand voltage of 2700 Volts DC for 2 seconds at 25 °C. Advanced overload resilience delivers four times the nominal current for 10 seconds or 1.5 times for one minute per hour, with saturation attenuation roll-off of 6 dB at 2.5× to 3× Iₙ.

Designed for seamless integration into drive systems, the NFD03.1-480-055 simplifies EMC compliance without external components when paired with a suitably grounded isolation transformer. Its IP20-rated housing, vertical mount configuration, and proven protection characteristics ensure reliable converter performance in industrial cabinets. Ideal for high-power HCS converter installations, it maintains stable line conditioning and minimizes downtime in demanding applications.
