Product Description:

The HNL01.1E-0098-N0280-N-690-NNNN is a three-phase mains choke developed by Bosch Rexroth Indramat for the HNL Mains Chokes series. Installed ahead of frequency converters or servo drives, the choke inserts a calculated reactance into the incoming line to suppress harmonic current, damp inrush, and stabilize the DC-link voltage. Within automated cells or machine tools it therefore protects input rectifiers, extends capacitor life, and helps plants remain inside utility disturbance limits.

Its open construction carries a protection rating of IP00, so the unit relies on the surrounding cabinet for touch-safe shielding and airflow. The copper windings are sized for a mains window of 3 x AC 380 V -15% … 3 x AC 690 V +10%, allowing one choke to cover common low- and medium-voltage feeds. Marked as Design Version 1, the core geometry and terminal layout match the first electrical revision, while the hardware index is stated as Series 01 for straightforward cross-reference to spare parts. The supply interface is classified as Feeding, indicating that the component is wired on the network side and is not intended for regenerative operation or output-phase smoothing.

According to Bosch Rexroth Indramat, the configuration table lists Additional Options: None, and the variant field confirms Other Designs: None. This minimalist approach anchors the choke to the baseline HNL Mains Choke specification, keeping weight, inductance, and mounting footprint unchanged across orders. With no varnish, integrated fuses, or thermal sensors to manage, design calculations can focus purely on cabinet airflow and conductor sizing. In retrofit scenarios this clarity speeds approval because the electrical stress, impedance, and short-circuit endurance are identical to those already validated on the production floor.
