Product Description:

The HNL01.1R-6300-S0065-A-480-NNNN is a mains choke produced by Bosch Rexroth Indramat for the HNL Mains Chokes series. Installed between the supply network and a regenerative drive line, it adds inductance on the line side to limit current peaks created by rapid power conversion in automated machinery. This reduces harmonic content seen by the utility connection and helps protect connected inverters from sharp electrical stress. By smoothing the current drawn from the line, it helps keep the supply interface more stable during switching events inside the drive system.

Electrical compatibility includes a rated input of 3 x AC 400–480 V -15/+10%, 50/60 Hz, so the choke can be connected to common three-phase utility networks. The enclosure has an IP10 rating, which protects against accidental finger contact and requires installation inside a closed cabinet with suitable protection from dust and moisture. Its current-compensated winding set balances opposing magnetic fields to reduce leakage flux and audible noise at low load. The choke is intended for a regenerative supply system, allowing bidirectional power flow when braking energy is returned to the line. The voltage and frequency range also supports normal plant variation on incoming power without changing the basic electrical role of the component.

The unit is in design version 1, which marks the initial build level and matches the corresponding mounting geometry. It is grouped in Series 01 with mechanically similar models in the same range, which helps keep physical integration consistent within related assemblies. In cabinets that use regenerative drives, the choke contributes to line-side harmonic attenuation and reduces di/dt stress on upstream power components. Because it is a passive line component, this conditioning takes place without separate control electronics or additional operating adjustments inside the cabinet.
