The VW3AE0111 is a circuit-breaker accessory from Schneider Electric, designed for the Altivar 71 Plus and Altivar 61 Plus drive series. It mounts specifically in the floor-standing enclosure variants — both the version with separate air flows and the compact version — serving as a protection accessory in the drive's power path.
This breaker is a protection accessory destined for Altivar floor-standing enclosures — the large-cabinet builds that house the 71 Plus and 61 Plus drives. It is not a panel-mount DIN-rail breaker; it integrates into the drive's own enclosure layout, so the fit is specific to those cabinet variants.
