The VW3AE0158 is a 230 V motor for circuit-breaker, designed as a protection accessory for Altivar floor-standing enclosures with separate air flows or the compact version. It belongs to the Altivar 71 Plus and Altivar 61 Plus range.
This part is officially obsolete per the manufacturer's lifecycle status.
The motor mounts inside an Altivar floor-standing enclosure — the variant with separate air flows or the compact version. It drives the circuit-breaker mechanism, so the mechanical interface and mounting points are specific to those enclosure designs. If you're retrofitting into an existing Altivar 71 Plus or 61 Plus cabinet, verify the enclosure version matches the 'separate air flows or compact' destination before committing the line.
