Product Description:

The HNF05.1A-500N-R0180-N-A5-NNNN is a passive mains filter produced by Bosch Rexroth Indramat for the HNF Mains Filters series. Installed between a plant's three-phase utility and an IndraDrive converter, it suppresses conducted interference and channels regenerated energy back to the grid during braking events. This arrangement supports regenerative operation without sending returned energy into a separate dissipation device. The unit belongs to series 05 and is supplied in design version 1, which indicates its place within this filter range.

It is rated for a continuous current of 180 A, allowing it to carry the full output of medium-power regenerative drives without saturating its inductive elements. Connection is made through 3 × AC terminals, so each phase is processed symmetrically. During operation, the filter dissipates only 34 W of power, which helps limit temperature rise inside the cabinet. A leakage capacitance of 500 nF offers a low-impedance path for high-frequency common-mode noise while keeping earth leakage within safety limits. Conducted emissions fall under C3 in accordance with DIN EN 61800-3, which suits installation in restricted industrial zones.

With a protection degree of IP00, the filter must be mounted inside a closed electrical enclosure where contact and debris ingress are controlled. Its compact envelope of 170 × 330 × 141 mm conserves panel space, and the 13 kg mass allows placement on standard horizontal plates without extra reinforcement. Because it is intended for regenerative devices only, the internal network of inductors and capacitors is tuned for reverse energy flow instead of internal absorption. The unpainted housing matches other HNF components and helps maintain consistent wiring clearances and thermal spacing across multi-axis systems.
