The VW3AP0611 is a dv/dt filter choke designed for Schneider Electric's Altivar Process ATV600 and ATV900 drive families. It's a protection accessory that sits between the drive output and the motor cable, rated for drive systems in the 110 to 160 kW power band with a 300 m cable length capability.
Sourcing Reality: Active, But Not a Standalone Item
The critical sourcing constraint is the condition of use: this part cannot be ordered alone. It's only available in combination with a standard enclosure. That means if you're building a BOM for a drive system, you need to pair this filter with the correct ATV600 or ATV900 enclosure variant — it won't ship as a loose component.
What the dv/dt Filter Does for Your Drive System
A dv/dt filter limits the rate of voltage rise at the motor terminals. On a 110–160 kW drive feeding a long cable run — up to 300 m with this choke — the reflected wave phenomenon can double the voltage at the motor, stressing winding insulation. This filter chokes that rise time, protecting the motor without the insertion loss of a full sine-wave output reactor. It's sized for compact drive system integration, meaning it fits within the standard enclosure footprint rather than requiring a separate cabinet.
Integration Note for Panel Builders
Because this filter ships as part of a standard enclosure assembly, the panel builder doesn't need to allocate separate DIN-rail space or gland-plate entries for it — it's already integrated into the drive system's mechanical layout. The 300 m cable-length rating is the maximum motor cable run the filter supports; exceeding that risks exceeding the dv/dt limit and voiding the motor warranty. Verify your cable length against that figure before specifying the enclosure combination.
