Product Description:
The HNL01.2R-0980-C0026-A-480-NNNN is a three-phase mains choke produced by Bosch Rexroth Indramat for the HNL Mains Chokes series. Installed ahead of a drive controller, the inductor raises line impedance, limits current spikes, and attenuates high-frequency noise. By keeping the input current more sinusoidal, it helps drives meet electromagnetic compatibility limits and protects upstream fuses and contactors from excessive di/dt. Within an automation cell, this choke contributes to stable DC-link voltage and longer component life.
The device carries a degree of protection of IP10, meaning its vented housing blocks accidental contact with live conductors but does not seal against dust or moisture. It is intended for grids that deliver 3 × AC 400–480 V within a tolerance of -15% to +10%. Compatibility with supply frequencies of 50/60 Hz allows the choke to operate on either frequency. Because the connected drive operates on a regenerative supply system, the inductor accommodates bidirectional power so returned energy can pass back to the utility. A factory-installed option with capacitors is wired in parallel with the winding to smooth residual ripple and reduce switching peaks at the converter input.
Version 2 of this coil uses tighter impedance tolerances, which helps harmonic filtration when multiple units are connected in parallel. Identification as Series 01 places the component in the initial mechanical frame size, so mounting points remain identical across power ratings in that subset. Within the broader HNL Mains Chokes family, this variant matches converters from the same production period of Bosch Rexroth Indramat. That pairing supports consistent electrical behavior in modular drive panels that use compatible regenerative power arrangements.
