Product Description:

The HNL05.1R-0080-N0238-N-A5-NNNN is a line reactor manufactured by Bosch Rexroth Indramat for the HNL Mains Chokes series. Designed for three-phase power networks, the component is wired ahead of drive converters to increase circuit impedance, reduce harmonic distortion, and limit peak current during switching events. In automated machinery, placing a mains choke at the cabinet entry protects sensitive electronics and improves incoming power quality without adding active devices. Because it is a passive line component, it works continuously as current passes through the windings and does not require separate control circuitry.

Its core electrical parameter is a nominal inductance of 80 µH, which creates voltage drop as current changes and helps suppress high-frequency components on the incoming line. The device handles a continuous line current of 238 A, allowing it to serve multi-axis inverter groups without saturation during normal operation. Compatible mains terminals accept 3-phase AC 525 V to 690 V supplies, covering the utility range commonly found in industrial facilities. It operates over standard network frequencies of 50/60 Hz. A construction rating of IP00 means the coil assembly is open and must be installed inside a protected cabinet where accidental contact is prevented.

Heat is removed by natural convection, so cabinet layouts must leave clear air paths around the winding surfaces. An integrated EMC filter is built into the same assembly, which helps reduce conducted noise on the supply side. The choke is suitable for regenerative supply systems that return braking energy to the mains, and this arrangement helps support stable input conditions during rapid load changes. The unit is version 1. A mass of 25 kg affects panel support requirements and calls for secure mounting hardware.
