The VZ3V320S3 is an official Schneider Electric fan kit for the Altivar Machine ATV320 series of variable speed drives, specifically designed for the S3 frame size. It is classified as a cooling accessory (category US1CP4B22149) and is a wear part — meaning it has a finite service life and is intended to be replaced when the drive's internal fan fails or reaches its bearing life. The kit composition includes the fan itself, a mounting bracket, and an instruction sheet — everything needed for a field swap without ordering separate hardware. Single-unit packaging (1 per kit).
Lifecycle reality — obsolete, not a dead end
Schneider has marked the VZ3V320S3 as Obsolete. No direct drop-in replacement from Schneider's current catalog is confirmed here.
