Telemecanique VW3A4554 AC Line Choke

Description

The Telemecanique VW3A4554 is a three-phase AC line choke, also known as a line reactor, designed for use with variable speed drives. This robust component is installed at the input of a frequency inverter to improve power quality by reducing harmonic distortion, mitigating voltage spikes, and limiting inrush currents. It enhances the overall reliability and lifespan of the motor drive system.

FAQ

The VW3A4554 is installed on the input side of a variable speed drive to reduce harmonic currents sent back into the power grid, protect the drive's input rectifiers from voltage spikes, and limit peak inrush currents.

This line choke was originally designed for the Schneider Electric Altivar 61 (ATV61) and Altivar 71 (ATV71) series of frequency inverters, particularly for models in the 11 kW to 15 kW power range.

While electrically it might be possible, it is not recommended. Modern drives are optimized with specific choke characteristics. For new installations or replacements with Altivar Process drives, you should consult the official Schneider Electric documentation to select the correct, currently supported line choke.
