The VW3AP0254 is a motor operator for the circuit-breaker on Altivar Process ATV600 and ATV900 drive systems sized 560 to 630 kW. It runs on 230 V AC supply and is classified as a protection accessory — it powers the breaker's opening and closing mechanism, not the drive itself.
Critical ordering constraint: this part cannot be purchased alone. The manufacturer specifies it only in combination with a standard enclosure. If you are sourcing a replacement motor operator for an existing ATV600 or ATV900 cabinet, confirm that the enclosure assembly is part of the same order line — a bare VW3AP0254 without the enclosure will not ship as a standalone line item.
Integration is straightforward if you are working on a Drive Systems cabinet in the 560–630 kW range. The motor operator mounts to the circuit-breaker within the standard enclosure; the 230 V AC control signal comes from the drive's auxiliary supply or an external control transformer. Verify that the existing breaker frame accepts this operator — the ATV600 and ATV900 families share the same accessory platform, so cross-family compatibility is designed in.
