The VW3AP0105 is a circuit-breaker protection accessory for Schneider Electric's Altivar Process ATV600 and ATV900 compact drive systems, sized for the 560 and 630 kW power range. It's a line-side disconnect and overcurrent protector that lives in the drive's standard enclosure — the spec sheet says it cannot be ordered alone, only in combination with that enclosure.
Rated for the 560 and 630 kW drive tier — that's the headline fit parameter. If your ATV600 or ATV900 is below that power band, this breaker is oversized and won't coordinate properly. The compact drive system designation means it's designed for the pre-engineered drive cabinet, not a custom panel. The enclosure integration is mandatory: the breaker's mounting and bus bar connections are keyed to the standard enclosure's backplate and buswork.
