Product Description:

The HNL01.1R-0180-N0650-A-480-NNNF/S126 is a line reactor produced by Bosch Rexroth Indramat within the HNL Mains Chokes series. As a mains choke, it is installed between the plant power grid and regenerative drive modules to add impedance, smooth line current, and reduce harmonic distortion. By limiting inrush and peak currents, the device protects converters, stabilizes DC bus voltage, and supports reliable operation in automation equipment that returns energy to the network during braking cycles. Because it is placed on the AC input side of the drive system, it conditions the incoming supply before power reaches the converter section.

This choke connects to three-phase supplies rated at 3 x AC 400–480 V -15/+10%, 50/60 Hz, matching common industrial power classes. Its housing carries a protection level of IP10, so airflow remains open while live parts are guarded against accidental contact. The component belongs to internal series code 01 and is built as design version 1, which keeps the mechanical layout and wiring scheme consistent within the same frame. Because the associated frequency converters can return energy, the choke is intended for a regenerative supply system, so its inductance and thermal profile suit two-quadrant power flow. The enclosure style is suited to protected cabinet mounting, and the stated voltage range fits a broad span of industrial line conditions.

The unit remains part of the HNL Mains Chokes line and is used in drive systems that exchange energy with the supply during braking. Its added line impedance helps limit peak input current, while harmonic reduction and current smoothing support steadier behavior on the connected power line. The reactor works as a passive inductive element in the incoming line path, so it does not require active switching hardware or a separate control circuit. This arrangement helps moderate electrical stress on upstream distribution equipment during rapid load changes and repeated deceleration events.
