Product Description:

The HNL01.1E-0600-N0032-A-500-NNNN is a line choke produced by Bosch Rexroth Indramat and assigned to the HNL Mains Chokes series. Installed on the mains side of a drive system, it adds inductance to the feeder circuit so that inrush current and voltage transients are reduced before they reach sensitive inverters and servo amplifiers. By tempering the steep edges of the incoming sine wave, it helps limit total harmonic distortion, protects switching components, and contributes to electromagnetic compatibility within industrial automation cabinets. This added impedance also lowers the rate of current change at power-up, which helps reduce stress on rectifiers, capacitors, and other line-side input components.

The unit has a protection category of IP10, indicating an open-frame design that permits airflow while still guarding against accidental finger contact. It accepts a three-phase supply of 3 x AC 380...500 V -15/+10%, allowing installation on standard plant distribution networks that may experience moderate voltage variation. Compatible line frequencies of 50/60 Hz cover both international and North American grids, so the same model can be used on machinery deployed in different regions. Because the choke is intended for a feeding supply system, it is wired directly in series with the utility line, adding impedance that smooths the current drawn by downstream variable-frequency drives.

This hardware belongs to design revision 1, and its electrical dimensions and mounting footprint match the initial release. The internal numbering shows that it is part of Series 01, which groups models with similar magnetic core geometry and thermal behavior. That grouping helps keep electrical behavior consistent across comparable units in the same platform. The choke is installed ahead of the connected drive, so incoming and outgoing power conductors can be routed directly through the reactor terminals inside the cabinet.
