Product Description:

The HNL01.1R-0190-N0300-A-480-NNNN is a mains choke built by Bosch Rexroth Indramat and assigned to the HNL Mains Chokes series. It is wired between the facility supply and an IndraDrive or similar drive controller, where it adds line reactance on the input side of the power system. In regenerative industrial power systems, this passive component limits line-side current peaks and smooths returned energy before it reenters the grid. The choke works as an auxiliary filter ahead of the drive input, reducing the severity of harmonic and current disturbances seen at the supply connection.

It operates on a mains connection voltage range of 3 × AC 400–480 V (–15/+10 %) at 50/60 Hz, which suits common low-voltage three-phase networks used in industrial cabinets. That range covers standard industrial supply levels in this voltage class without requiring a different choke for normal plant distribution systems. The housing has a degree of protection of IP10, so objects larger than 50 mm are blocked while ventilation openings remain available for airflow. Because the enclosure is not sealed against smaller debris or moisture, it is intended for protected cabinet installation rather than direct exposure on the machine. Mechanical identification follows design version 1, and the unit is intended for a regenerative supply system where active drives can return braking energy to the grid.

Internal winding dimensions correspond to series 01, so the inductance and copper cross-section follow the assigned standard for this choke size. Its fixed winding build keeps the magnetic core and conductor sizing matched to the intended electrical class of the device. The open enclosure supports convection cooling, which suits passive heat dissipation inside a ventilated control cabinet. No embedded fan modules, temperature sensors, or surge suppressors are included, so the hardware remains limited to the choke assembly and its main power connections.
