Product Description:

The HNL01.2E-0240-N0106-A-500-NNNN mains choke is produced by Bosch Rexroth Indramat within the HNL Mains Chokes series. The component is installed on the three-phase line side of servo drives and converters so its inductance can damp line transients, reduce harmonic distortion, and protect the upstream supply network. By limiting inrush current and smoothing the voltage waveform, the choke supports longer capacitor life in connected drives. That reduction in line stress helps rectifier sections draw current more evenly from the supply. In converter-based motion systems, cleaner input current can also reduce nuisance trips caused by sharp voltage disturbances.

The enclosure has an IP10 rating, which provides finger protection while still allowing free air circulation for heat dissipation. The coil accepts a nominal line of 3 x AC 380–500 V -15/+10%, 50/60 Hz, so it can be connected to common industrial power systems without tap changes. Its magnetic core and winding set correspond to design version 2, so the unit matches the second release of the 01 platform for mounting dimensions and thermal behavior. The choke is intended for a Feeding supply system, which places it ahead of the converter rather than in the regenerative path. Because cooling depends on open airflow around the core and windings, the cabinet layout should not block the sides or top of the component.

The part belongs to series code 01 and is supplied with no additional options. The unit is meant for line-side use and is not intended for placement in the motor output path. Its open enclosure requires installation in a switch cabinet with suitable spacing and protection from accidental contact. A sealed housing is not expected for normal cabinet use, so ventilation around the choke can remain unobstructed. This arrangement suits standard control cabinets where surrounding panels and adjacent equipment provide the necessary external guarding.
