Product Description:
The HNF01.1A-N1K0-R0450-A-480-NNNN line filter is produced by Bosch Rexroth Indramat for use within the HNF Mains Filters series. The unit is installed between plant distribution panels and regenerative drive modules to attenuate high-frequency noise and return excess braking energy to the power line. Its compact, air-cooled construction suits enclosed control cabinets that support motion axes on conveyors, presses, and other automated machinery. This placement helps reduce line disturbances before they spread through the cabinet supply. By limiting switching spikes seen by upstream breakers, it supports stable network conditions in production environments.
The filter carries a degree of protection of IP20, so live components are finger-safe but still require an enclosure to block dust or moisture. It accepts a supply of 3 × AC 400…480 V and continues to operate across a line swing from -15% to +10%, which keeps the choke and capacitor network within thermal limits during brownouts or voltage peaks. A fundamental frequency of 50/60 Hz allows the same hardware to be used on European and North American grids. Electromagnetic behavior is rated as C3, a category intended for industrial locations with dedicated transformers and long cable runs.
The mechanical construction corresponds to Design Version 1, with the mounting pattern and terminal orientation used for this product version. The product also uses series code 01 for identification within the line. Compliance is verified against DIN EN 61800-3, which provides a clear reference for machine EMC documentation. That standard is commonly used when recording conducted and radiated interference data for industrial drive assemblies. The filter is intended for regenerative devices only; connecting it to non-regenerative inverters would bypass the energy-return path and could overload the damping stage.
