Product Description:
The HNF01.1A-P2K0-R0800-A-480-NNIT is a three-phase mains filter produced for industrial automation by Bosch Rexroth Indramat and belongs to the HNF Mains Filters series. Installed on the line side of regenerative drive packages, the unit minimizes high-frequency noise and provides a controlled path for energy that flows back from active front-end inverters to the utility grid. By doing so, it helps protect adjacent equipment, supports electromagnetic compatibility compliance, and contributes to stable power quality in factory distribution panels. That role is especially relevant in cabinets that group several converters and sensitive control electronics on the same plant feeder.
The enclosure carries a protection rating of IP20, so terminals are finger-safe, but the device must be mounted inside a cabinet. At the input, it accepts 3 × AC 400–480 V, which allows common low-voltage plant networks to feed the filter without tap changes. The voltage range also supports facilities that operate near either end of the common industrial supply band. Operation is synchronized to grids running at 50/60 Hz, enabling use in regions that follow either frequency standard. Conducted emissions are classified in EMC Category C3 according to DIN EN 61800-3, meaning the filter is intended for industrial low-impedance supplies where additional mitigation is permissible. The unit is Design Version 1, which identifies the product revision used for this filter. Its cabinet-only installation matches the open terminal design used on line-side components.
The filter is intended for regenerative devices only, so it is matched to converters that return braking energy rather than dissipate it in resistors. Within the HNF Mains Filters series, the unit is identified further by hardware release 01. This revision marker distinguishes the filter variant used where a specific impedance curve must be referenced. The identification is useful when system documentation separates filter behavior by revision rather than by model family alone.
