The VW3AP0106 is a circuit-breaker protection accessory for Schneider Electric's Altivar Process ATV600 and ATV900 compact drive systems, sized for the 710 and 800 kW drive frames. It belongs to the protection accessory category and is designed as a dedicated component for the compact drive system architecture — not a standalone breaker you can drop into any panel. A key sourcing constraint: this part cannot be ordered alone; it is only available in combination with a standard enclosure. That means if you're planning a spare or a retrofit, you need the enclosure as part of the same order.
For a mature part like this, availability through independent distribution is generally stable.
Rated for Altivar Process ATV600 and ATV900 drives at 710 and 800 kW — that tells you the breaker is sized for the DC bus or input protection of those specific drive frames, not for general branch-circuit protection.
