The VW3AP0112 is a circuit-breaker protection accessory for Schneider's Altivar Process ATV600 and ATV900 compact drive systems, shipped with an integrated Micrologic trip unit. It is a factory-matched breaker for the drive enclosure — not a standalone panel component — and cannot be ordered alone; it must be specified in combination with a standard enclosure.
This circuit breaker ships as part of the compact drive system assembly. The Micrologic trip unit provides adjustable protection coordination for the drive's input stage.
