The Schneider VW3A66441 is a three-phase EMC filter rated for 110 A continuous current, designed to attenuate conducted emissions on the line side of a variable-speed drive or inverter.
This filter is classified as obsolete by the manufacturer.
Rated for 110 A three-phase, this filter sits between the mains supply and the drive input. Mount it close to the drive line entry — long input cables before the filter can radiate noise the filter cannot suppress. The three-phase design suits 400 V class drives in panel or enclosure builds.
