The VW3AE0666 is a sinus filter from the Altivar 71 Plus range, designed as a protection accessory for Altivar floor-standing enclosures with separate air flows or compact versions.
Schneider has marked this part obsolete. No direct successor is listed, so verify fit with the existing enclosure model before committing.
This sinus filter mounts inside an Altivar floor-standing enclosure, not a standard DIN-rail panel. The separate-air-flow or compact version designation means the enclosure's internal layout must accommodate the filter's thermal and clearance needs — check the drive's installation manual for the specific slot and ducting requirements.
