The VW3AE0190 is a mechanical isolating handle for the main disconnect switch on an Altivar floor-standing enclosure — specifically the Altivar 61 Plus-LH range with separate air flows or the compact version. It is the handle you mount on the enclosure door to reach the rotary switch inside, so maintenance can lock out the drive without opening the panel.
This is not an electronic component with current or voltage ratings — it is a mechanical handle. The only fit criteria are the enclosure model and the switch interface. It is designed for Altivar floor-standing enclosures with separate air flows or the compact version, so if you are retrofitting a drive in a standard IP23 or IP54 cabinet, confirm the door cutout and shaft length match the existing rotary switch. No wiring, no coil draw, no backplane budget to track.
