The Schneider Electric VW3GB661323F1 is a 23 A line filter from the R-FP U72 series, designed to attenuate conducted EMI on the input side of a variable-speed drive. The 23 A rating sizes it for drives drawing that continuous input current, typically on 400 V three-phase systems.
Mounts inline between the line supply and the drive input. The R-FP U72 form factor is a panel-mount enclosure with cable entry points; no DIN-rail clip is standard. Verify the mounting footprint against the existing panel layout before specifying.
