The VW3AE1201 is a remote control terminals X12 connection accessory for Schneider Electric Altivar floor-standing drives with separate air flows or compact enclosures. It is listed for the Altivar 71 Plus, Altivar 61 Plus, Altivar 71 Plus-LH, and Altivar 61 Plus-LH ranges.
The X12 remote control terminals are specific to the Altivar floor-standing enclosure variant with separate air flows — not the standard IP20 or IP54 wall-mount drives. If your installed base is an Altivar 71 Plus or 61 Plus in a floor-standing cabinet with segregated cooling paths, this is the correct terminal block set for remote control wiring. The accessory type is connection accessory, so it provides the physical screw-clamp or spring-cage interface for control signals (speed reference, run/stop, fault reset) routed from a remote operator station.
