The VW3AE2601 is an insulation monitoring device designed for IT (ungrounded) power systems, used as a protection accessory inside Altivar 61 Plus, Altivar 61 Plus-LH, Altivar 71 Plus, and Altivar 71 Plus-LH floor-standing enclosures with separate air flows or compact versions. It monitors insulation resistance on the IT network and signals a warning or trip before a second ground fault can cause a phase-to-phase short — critical for maintaining uptime on drives powering conveyors, pumps, or fans in a continuous process line.
Schneider Electric has marked the VW3AE2601 as obsolete. The lifecycle stage is 'mature', but the official product status is Obsolete, meaning no further production.
The VW3AE2601 ships as the insulation monitoring device itself — no mounting bracket, wiring harness, or terminal block kit is listed as included. For a kitting lead building a spare-parts kit for an Altivar 71 Plus cabinet, confirm the enclosure's accessory mounting provisions separately. The part is an isolation accessory, not a standalone panel-mount unit; it mounts inside the drive's floor-standing enclosure.
