Schneider Electric ATV320U40N4B Altivar 320 4kW 3-Phase 380-500V Book Mount Variable Speed Drive

The Schneider Electric ATV320U40N4B is an Altivar 320 series 4 kW variable speed drive designed for 3-phase 380–500 V applications, delivering precise frequency and torque control in a compact book-mount form factor. Engineered for industrial motor control environments where space efficiency is critical, this VSD enables significant energy savings by matching motor speed to actual load demand. The ATV320U40N4B suits a wide range of machinery including pumps, fans, conveyors, and compressors requiring reliable variable frequency drive performance.

Technical Specifications

Applications & Use Cases

• Pump & Fan Control: Optimise flow rates and reduce energy consumption by running motors at demand-matched speeds rather than fixed line frequency.
• Conveyor & Material Handling: Smooth acceleration and deceleration protect mechanical components and improve process reliability on production lines.
• Compressor Drives: Variable torque control allows compressors to modulate output precisely, reducing wear and lowering operating costs.
• OEM Machine Integration: The book-mount format enables side-by-side drive installation, maximising panel density in compact control cabinets for machine builders.
• HVAC Systems: Energy-saving speed regulation of air-handling and cooling equipment in commercial and industrial buildings.
