Product Description:

The HNL01.1E-0240-N0106-A-500-NNNN is a line reactor manufactured by Bosch Rexroth Indramat under the HNL Mains Chokes series. The component is installed on the line side of a drive system so it smooths current peaks and attenuates line-borne interference before energy reaches sensitive servo inverters or power supplies. By adding inductive impedance directly in the supply circuit, the choke helps maintain power quality and reduces stress on upstream breakers and downstream electronics during high di/dt events in automated production equipment.

The choke has an enclosure protection rating of IP10, which means it blocks solid objects larger than 50 mm while leaving ventilation openings available for heat dissipation. It accepts a three-phase input range of 3 × AC 380–500 V and supports normal tolerances of −15% to +10% around that range; the associated supply frequency is 50/60 Hz, allowing operation on many industrial power systems. The choke is version 1, so terminal locations and mounting-hole positions follow the first mechanical release of the series. It is intended for feeding-side use, which means it is installed ahead of the drive rather than on the motor side and must withstand full network fault levels.

The unit belongs to Series 01, which keeps the mounting footprint consistent across the current range and supports standardized panel layouts. It is supplied without auxiliary taps or built-in filters, so the reactor remains a straightforward input component for the drive supply. Within the HNL Mains Chokes series, the unit uses a standardized footprint that helps maintain consistent enclosure spacing when similar reactors are installed in adjacent sections. The open enclosure should be mounted inside a protected cabinet, and airflow around the winding should remain unobstructed so heat can dissipate normally.
