Product Description:
The NFD04.1-440-180 is a three-phase mains filter built by Bosch Rexroth Indramat for the NFD Mains Filters series. Integrated ahead of inverters and servo drives, the component suppresses conducted electromagnetic interference and prevents disturbances from propagating on the supply network. By presenting high impedance to switching harmonics while passing fundamental power, it supports compliance with industrial EMC directives and maintains stable operation of adjacent automation equipment. Its compact housing format lets the unit mount inside central control cabinets without changing the overall layout.
The filter is rated for a continuous phase-to-phase voltage of 3 x 440 VAC; this matches standard industrial mains and allows direct wiring without step-down transformers. A maximum load of 180 A can flow through the inductive network before saturation, making the device suitable for multi-axis cabinets. When installed in systems that must meet EN 55011, its attenuation curve aligns with Class A emission limits, so conducted interference remains below the allowable threshold on supply conductors. The housing spans an overall width of 404 mm, leaving space for internal windings and capacitors yet still fitting common 600 mm deep enclosures. Internal losses are limited to 39 W under full current, reducing excess heat that the panel ventilation must remove.
Mechanical integration is simplified by the mounting detail: slots 6.6 ±0.2 mm wide align with a center pitch of 82.5 ±0.2 mm, so the enclosure can be fixed to DIN rails or backplates without additional drilling. The sheet-steel body has a maximum width of 301 mm, a depth of 141 mm, and a height of 171 mm, allowing clearance in crowded electrical panels. Cable lugs up to a cross-section of 95 mm² clamp into the input and output terminals, supporting low-resistance connections at high current. Protective earth continuity is achieved through a M10 ground stud, and the total assembly mass of 13.0 kg provides enough inertia to damp vibration without overloading light-gauge mounting plates.
