Product Description:
The NFD01.1-440-110 is a passive three-phase mains filter manufactured by Bosch Rexroth Indramat within the NFD Mains Filters series. Installed ahead of drive controllers, it attenuates conducted electromagnetic noise and improves the power quality delivered to automation equipment. By adding inductance and capacitance between line and earth, the unit reduces high-frequency interference that could otherwise reach upstream feeders or nearby control electronics. This helps stabilize the incoming supply path for sensitive drive and control hardware in industrial cabinets.
At an ambient reference of 45 °C, the filter carries a continuous load of 110 A. Its nominal line voltage rating is 440 V, matching common industrial distribution levels and allowing connection directly to the incoming feeder without a step-down transformer. Designed for networks that supply three energized conductors, the phase count is 3, so the internal inductors and capacitors are arranged symmetrically across all phases. Short-term overload performance supports up to 1.5 × IN for no longer than 1 min/h, giving headroom for temporary current peaks during dynamic machine operation. The 45 °C current rating marks the thermal limit, so higher ambient temperatures require derating to prevent excessive capacitor heating or magnetic core saturation. This operating profile makes the filter suitable for drive systems that experience changing load conditions during normal use.
Dielectric integrity is verified by a ground isolation test of 2800 VDC between the filter chassis and each phase, while the inter-phase line test is performed at 2125 VDC. For a low-impedance protective earth path, the minimum PE conductor cross-section is 10 mm², sized to carry prospective fault currents without excessive temperature rise. The enclosure carries an IP10 rating, blocking accidental contact with live parts yet requiring placement inside a sealed cabinet for environmental protection. The filter should be mounted where cabinet wiring, grounding, and spacing can follow these electrical limits. Proper enclosure placement also helps keep dust, moisture, and incidental contact away from energized sections during operation.
