Product Description:
The HNF05.1A-500N-R0600-N-A4-NNNN mains filter is manufactured by Bosch Rexroth Indramat and belongs to the HNF Mains Filters series. It is installed ahead of regenerative drive groups to attenuate conducted interference and to return surplus energy to the plant supply without disturbing neighboring automation nodes. By inserting this filter between the inverter cabinet and the facility bus, the system can meet internal EMC limits while protecting transformers, sensors, and fieldbus electronics that share the same power backbone.
Design version 1 in the 05 series exposes open terminals, so its degree of protection is IP00. The unit accepts line voltages within 3 x AC 380 V -15% … 500 V +10% and sustains performance on both utility and local isolation transformers. It is rated for 50/60 Hz networks, allowing use on global grids without modification. A continuous load of 600 A can flow through the filter, matching the demands of multi-axis regenerative drive cabinets. Internal core losses and damping components account for a power dissipation of 86 W, so panel ventilation or forced-air cooling must be considered during layout.
The copper path introduces only 52 µΩ of line-to-line resistance, minimizing additional voltage drop while still providing differential-mode damping. The filter network yields a leakage capacitance of 500 nF, which sets the ground leakage current that upstream protective devices must accommodate. With a shipping weight of 22 kg, the assembly is typically fastened to reinforced DIN rails or a solid base plate. It meets EMC category C3 in accordance with DIN EN 61800-3, which is intended for industrial areas that are not directly connected to the public low-voltage supply.
