The VW3AE0108 is a circuit breaker accessory purpose-built for the Altivar 61 Plus drive family, specifically the floor-standing enclosure variant with separate air flows or the compact version. It sits in the protection accessories category — meaning it's the branch-circuit overcurrent device integrated into the drive cabinet, not a standalone panel breaker.
The critical fit parameter here isn't a current or voltage rating (none is listed in the spec record) — it's the mechanical and electrical interface to the Altivar 61 Plus floor-standing enclosure with separate air flows or compact version. That destination code tells you this breaker mounts inside the drive cabinet, not on a DIN rail in a separate panel. If you're retrofitting or replacing a failed breaker in an Altivar 61 Plus cabinet, this is the factory-matched part.
