The VW3AE0151 is a circuit breaker accessory from Schneider Electric's Altivar drive family, designed as a protection accessory for Altivar floor-standing enclosures with separate air flows or compact versions. It fits the Altivar 61 Plus-LH, Altivar 71 Plus-LH, Altivar 71 Plus, and Altivar 61 Plus drive ranges.
Schneider has marked this part as obsolete.
This breaker is specific to Altivar floor-standing enclosures that use separate air flows or the compact version — not the standard IP23 or through-flow variants. If you're retrofitting or replacing a breaker in an Altivar 61 Plus or 71 Plus cabinet, the VW3AE0151 is the factory-specified protection accessory for that enclosure layout.
