Product Description:

The HNL01.1E-0080-N0309-A-500-NNNN is a three-phase mains choke manufactured by Bosch Rexroth Indramat in the HNL Mains Chokes series. It is used as a line reactor between the incoming power source and an inverter or servo drive. In that position, it helps limit inrush current, dampen supply disturbances, and reduce harmonic content in industrial automation systems. It is commonly used ahead of drive systems that draw pulsed current from the supply, where added inductance improves the electrical behavior of the input stage. This is especially useful in cabinets that power multiple motion components from the same line connection.

The choke connects to a rated line of 3 × AC 380–500 V with a tolerance of -15% to +10%, allowing direct use on common industrial utility feeds. It accepts mains frequencies of 50/60 Hz, so the same unit can operate on power systems used in different regions. The product is in build release 01, which identifies the initial production revision of the winding and material set. Its enclosure is rated IP10, so it blocks accidental contact with larger objects but still requires installation inside a protected electrical cabinet. The supply type is feeding, meaning the choke is intended for the line side rather than for motor output filtering.

The product is Version 1, which identifies this mechanical and thermal revision. It uses a standard copper winding with a laminated core to provide the intended inductance for line-side filtering. The copper-and-core arrangement helps maintain consistent performance as the choke warms under load. Terminal placement and mounting geometry follow the layout used for this revision, which helps the unit fit typical cabinet assemblies. This arrangement helps smooth current demand seen by the connected drive and reduces disturbances passed along the supply path.
