The Schneider VW3A4523 is a DC choke — a line reactor placed on the DC bus of a variable-speed drive to smooth current ripple and reduce harmonic distortion fed back to the supply. It carries a 290 A rated current and 0.15 mH inductance, sized for drives in that current class. The overload rating allows 1.65 x nominal current for 60 seconds, which covers the inrush and acceleration transient without saturating the core.
Sourcing reality — obsolete, not gone
Schneider lists the VW3A4523 as obsolete.
