Product Description:
The HNF05.1E-500N-R0320-N-A5-NNNN is a passive mains filter produced by Bosch Rexroth Indramat for the HNF Mains Filters series. This cabinet-mounted component is installed on the line side of converter systems in industrial automation. Its role is to block high-frequency interference generated by switching drives and to smooth current flow before energy returns to the plant supply. By conditioning power in both directions, the device helps protect sensitive upstream equipment and supports regenerative servo systems in meeting electromagnetic compatibility requirements across plant distribution networks. It also reduces conducted noise that could otherwise spread through facility wiring and affect nearby electrical equipment.
The enclosure has a protection rating of IP00, so the filter must be installed inside a closed electrical cabinet to prevent accidental contact. The filter is Design Version 1 and belongs to Series 05. Leakage current is shaped by a capacitance stack totaling 500 nF, which helps shunt common-mode noise without overloading residual-current devices. The unit is designed for 3 mains phases and has a continuous current capacity of 320 A at 40 °C. Its operating voltage range extends from 380 V -15 % to 690 V +10 %, allowing use on a wide range of industrial supply systems. This layout is suited to larger regenerative drive groups where line-side filtering is needed inside the control cabinet.
The filter is intended for regenerative devices only, so it is suited to drive systems that return braking energy to the grid. Its internal choke topology reduces differential ripple created during power feedback, which helps limit stress on upstream breakers and transformers. Installed ahead of the converter, it attenuates switching-related disturbances before they spread through the building supply. Proper cabinet airflow, bonding, and electrical clearances are still required for stable operation. The open enclosure rating also means the surrounding panel must provide the necessary touch protection.
