It features a supply system for feeding and supports a mains connection voltage of 3 x AC 380 to 500 V with a tolerance of -15% to +10% at 50 or 60 Hz. This choke has a degree of protection rated at IP10.
Internal Product Review
The HNL01.1E-0170-N0146-A-500-NNNN is a Bosch Rexroth Indramat HNL mains choke engineered for feeding supply systems. Support for 3 x AC 380 to 500 V at 50/60 Hz gives the unit solid compatibility with common industrial power architectures. IP10 protection makes the design a strong choice for enclosed cabinet applications requiring consistent mains conditioning.

Product Description:
The HNL01.1E-0170-N0146-A-500-NNNN mains choke is manufactured by Bosch Rexroth Indramat within the HNL Mains Chokes series. It is a passive inductive component installed at the input of frequency converters and servo drives in industrial cabinets. In operation, the choke sits between the plant’s three-phase utility feed and the rectifier front end, where it limits inrush current, filters high-frequency harmonics, and reduces di/dt on the line conductors. Adding this impedance helps protect upstream fuses, reduce electromagnetic interference, extend DC-link capacitor life in the connected power module, and smooth the current drawn by the front end during normal operation.
Its electrical ratings support use on three-phase systems from 380–500 V, and it tolerates line deviations of -15/+10% without magnetic saturation. Support for 50/60 Hz mains allows use on common industrial power systems without changes to the hardware. The enclosure is rated IP10, which provides protection against accidental contact with internal parts but does not seal against dust or liquids. Because of that enclosure type, the choke must be installed inside an enclosed control panel. Design 1 indicates the first engineering release and identifies this version of the product.
The internal series code 01 groups this model with units that share the same mounting footprint and thermal class. Its supply role is listed as Feeding, which means it is intended for placement on the network side rather than on the load side of an inverter. The iron core and winding cross section are sized to provide the required inductance while avoiding excessive voltage drop at rated current. The magnetic circuit supports stable line-side impedance across normal operating conditions, and the assembly is intended for cabinet-based integration with compatible drives and line components.
