The VW3AE0120 is an undervoltage coil for the circuit-breaker in Altivar 61 Plus and Altivar 71 Plus floor-standing enclosures — the compact and separate-airflow versions. It operates on a 110 V supply and drops the main breaker if control power is lost, giving you a controlled coast-down rather than a hard trip on a brownout.
This part is officially obsolete per Schneider's lifecycle status. No direct successor order code is listed. For a line running an Altivar 61 Plus or 71 Plus cabinet, the VW3AE0120 is a critical spare — one in the cabinet before it fails.
