Product Description:

The HNL01.1E-0026-N0620-N-690-NNNN is a three-phase mains choke produced by Bosch Rexroth Indramat for use in industrial drive assemblies that draw power directly from utility lines. As a member of the HNL Mains Chokes series, this component is installed ahead of a frequency inverter or servo drive to raise circuit impedance, thereby damping line-side current peaks and reducing conducted electromagnetic disturbances.

Manufactured by Bosch Rexroth Indramat, the choke belongs to the HNL Mains Chokes series and is identified as design version 1. A degree of protection rated at IP00 indicates that the coils and laminations are not enclosed, so the device must be mounted inside a cabinet that provides the required environmental shielding. The mains connection accepts voltages from 3 × AC 380 V to 3 × AC 690 V, allowing it to pair with medium-voltage feeds typical of European and global factory grids while accommodating –15 % undervoltage and +10 % overvoltage excursions. When inserted between the mains and a drive, the choke’s distributed leakage inductance limits the di/dt of charging currents, which in turn reduces DC-link capacitor stress and extends drive service life.

Within the series catalog it is classified under code 01, and the supply system is specified as Feeding, meaning the choke is intended for line-side rather than motor-side placement. No supplementary filters or thermal sensors are integrated, as denoted by None in the additional options field, and no alternate winding or core variants are listed, so the product remains consistent with the baseline HNL Mains Choke electrical design. These attributes simplify selection for panel builders who need a fixed-impedance reactor that matches the nominal current of compatible Rexroth inverters without additional configuration steps.
