The Schneider Electric VW3AP0101 is a circuit-breaker protection accessory for the Altivar Process ATV600 and ATV900 compact drive systems, sized for the 110 to 160 kW power range.
Sourcing and fit constraints
A critical sourcing constraint: this part cannot be ordered alone — it is only available in combination with a standard enclosure. For a BOM line or MRO spare, the enclosure assembly must be specified alongside the breaker. As a protection accessory within the Altivar Process family, it integrates into the drive system's internal bus architecture, not as a standalone panel-mount breaker.
Rated for 110–160 kW drives, this breaker coordinates with the drive's input stage to provide branch-circuit protection without oversizing — critical for meeting the SCCR requirements of the panel assembly. Because it is a drive-system-specific accessory, the breaker's trip curve and interrupting capacity are matched to the ATV600/ATV900's DC bus precharge and inrush characteristics, not to generic motor loads.
