VW3A9921 Direct Circuit Breaker Mounting Kit for Altivar Machine ATV320 ATV32

The Schneider Electric VW3A9921 is a specialized mechanical mounting adapter kit designed to streamline control panel architecture. It enables the direct physical mounting of a TeSys GV2 manual motor starter/circuit breaker onto the face of a compatible Altivar variable speed drive (VFD).

By integrating the circuit breaker directly with the drive frame, this mounting bracket completely eliminates intermediate DIN rail spacing, optimizes heat-sink alignment, and significantly minimizes internal enclosure footprint. It provides a rugged mechanical union, ideal for high-vibration industrial environments.

Key Design Features:

• Maximum Enclosure Space Savings: Eliminates the typical wire-run space and spacing requirements between a circuit breaker and a VFD, facilitating ultra-compact control panel lay-outs.
• Streamlined Assembly: Allows for the pre-assembly of the drive and motor protector modules on the bench before dropping the unified system directly into the panel.
• Rugged Mechanical Stability: Securely locks the GV2 frame to the book-style Altivar chassis, preventing independent component flexing, wire-strain, or shifting over time.
