Product Description:

The HNL01.1E-0362-N0080-A-500-NPNN is a three-phase mains choke produced by Bosch Rexroth Indramat and assigned to the HNL Mains Chokes series. Placed between the plant supply network and a frequency converter, the device raises input inductance so that high-frequency harmonics are attenuated and peak inrush currents are smoothed. This operating role is important on rectifier-fed drive systems that draw current in short pulses from the AC line. By reducing these electrical stresses, the choke helps protect rectifier bridges, lowers conducted emissions, and improves overall power factor in automated production cells. It also helps stabilize the current taken from the supply during normal converter operation.

This model connects to grids rated at 3 x AC 380–500 V and tolerates a voltage variation of -15/+10%, allowing operation on feeders with moderate fluctuation. Compatible line frequencies of 50/60 Hz mean it can be used on both North American and international mains. The enclosure carries a protection level of IP10, so the unit must be mounted inside a control cabinet because the ventilation openings remain exposed to ambient air. The product is design version 1. The choke is intended for a feeding supply system, where it conditions incoming energy before it is distributed to inverters or servo drives.

The component is in series 01, which uses the corresponding core dimensions and terminal layout for this product group. The unit does not include optional thermal sensors or EMC shields, so it remains a basic line-conditioning component for cabinet installation. This makes the assembly more straightforward while keeping the electrical function focused on input inductance. Its winding geometry supplies the inductance needed to restrain di/dt while keeping copper losses within a practical range during continuous operation.
