The VZ3V32E100 is a factory-matched cooling fan kit for Schneider Electric's Altivar 320 variable-speed drives. It's sized for the 18 kW and 22 kW three-phase 500 V models — the two largest power ratings in the Altivar 320 family that share a common drive frame. If you're swapping a failed fan on one of those drives or building a spare kit for the panel, this is the direct-fit part.
What's in the box
The kit comes with the fan itself, a mounting bracket, and an instruction sheet. No separate wiring harness or thermal sensor — the fan plugs into the drive's existing header, and the bracket aligns to the pre-drilled chassis holes. A 10-minute swap for someone who's done it before.
Let me show you why the power rating matters here: the 18 kW and 22 kW Altivar 320 drives run hotter than the smaller frame sizes, so the fan is the only active cooling. If the fan stalls, the drive derates fast or trips on overtemperature. Keeping a VZ3V32E100 on the shelf means you swap it during a scheduled PM instead of chasing a thermal fault at 2 AM.
