Product Description:

The HNF05.1E-500N-R0180-N-A5-NNNN is a mains filter manufactured by Bosch Rexroth Indramat for use with regenerative drive packages in the HNF Mains Filters series. Positioned between the plant supply network and the inverter group, the unit attenuates harmonic feedback and limits high-frequency noise before it can propagate to upstream equipment. Because it belongs to the 05 line of the series, the filter shares mechanical mounting geometry with other HNF05 devices. It also helps preserve predictable wiring clearances when multiple filter and inverter sections are mounted side by side in one automation cabinet.

Its electrical window is tailored to three-phase AC systems. The filter accepts line potentials from 380 V AC up to 690 V AC, enabling deployment on both lower- and medium-voltage factory buses. The design tolerates excursions of +10% and -15% around the rated range, so the connected rectifier stack can ride through modest sags or surges without nuisance trips. Protection is classified as IP00, meaning live parts must be installed inside a separate enclosure and the device relies on the switchgear cabinet for shielding. The wide voltage span lets the same filter type fit different plant distributions without changing the basic cabinet arrangement.

Current-handling capacity reaches 180 A, matching multi-axis assemblies that regenerate significant power during rapid deceleration. The internal damping network exhibits a leakage capacitance of 500 nF, and that value must be considered when selecting residual-current protection because it affects the displacement current flowing to protective earth. The filter is Design Version 1, indicating the first mechanical iteration of this type. It is intended for regenerative devices only, so using it on passive loads would not support power feedback to the supply.
