The VW3AE2001 is a PTC relay accessory from Schneider Electric's Altivar drive family, designed for Altivar 71 Plus, Altivar 61 Plus-LH, and Altivar 71 Plus-LH floor-standing enclosures with separate air flows or compact versions. It operates on a 230 V AC supply and serves as a thermal protection relay for motor windings via PTC thermistor input.
Schneider Electric lists the VW3AE2001 as obsolete.
Rated for 230 V AC supply, this relay is intended for the control circuit of the Altivar drive enclosure, not for direct motor power. The PTC input monitors motor winding temperature; when the thermistor resistance exceeds the trip threshold, the relay opens the drive's safety chain. Mounts inside the Altivar floor-standing enclosure — verify panel space and wiring access before specifying.
