Product Description:

The HNF01.1C-F240-E0080-A-480-NNNN is a mains filter produced by Bosch Rexroth Indramat and supplied within the HNF Mains Filters series. This component is installed between the facility supply and Rexroth inverter systems to attenuate conducted interference and limit line-borne emissions, allowing multi-axis drive packages to meet machine-level electromagnetic compatibility requirements. Used in automation cabinets, the filter conditions incoming three-phase power so that connected converters operate with lower common-mode noise and reduced impedance-related stress.

The filter accepts three-phase input at 3 × AC 400–480V, making it suitable for standard low-voltage industrial grids, and it remains frequency-agnostic across 50/60 Hz networks so no derating is needed when equipment is shipped internationally. Its housing carries a protection rating of IP20, indicating finger-safe terminals yet requiring enclosure mounting for dust or moisture exposure. Electromagnetic performance is classified as C2, a designation inside DIN EN 61800-3 that mandates suppressed emissions for commercial power environments where dedicated transformer separation is not provided. The filter can support up to 6 axes on a single supply branch, enabling centralized harmonic mitigation without installing individual filters at every drive.

Mechanical details complete the profile: the wiring run from the filter to the inverters may extend to a max. cable length 240 m, giving plant designers freedom to lay out remote motor cabinets without additional line reactors. Hardware identification lists Design Version 1, so spare parts and documentation reference a consistent mechanical outline and terminal pattern. The unit is intended For feeding devices only; it is not designed to protect loads that regenerate energy back toward the mains. Within the HNF family, this model falls under internal series code 01, which groups filters sized for 80 A continuous RMS current on 480 V lines.
