The VW3AE0113 is a circuit breaker in the protection-accessory line for Schneider Altivar 71 Plus and Altivar 61 Plus drives. It mounts inside the Altivar floor-standing enclosure with separate air flows or the compact version — meaning it is sized for the larger cabinet builds, not the panel-mount or IP20 chassis drives.
What it protects
This circuit breaker sits between the mains supply and the drive input, providing overcurrent and short-circuit protection for the Altivar floor-standing enclosure. It is not a motor-protection device — that function belongs to the drive's own electronics or a separate thermal overload relay. The breaker's role is to isolate and protect the cabinet wiring and the drive's input rectifier stage.
