ATV320U55N4C Altivar Machine ATV320 5.5kW Compact AC Drive 380‑500V | Schneider Electric

The Original New Schneider Electric ATV320U55N4C is a 5.5 kW (7.5 HP) variable speed drive from the Altivar Machine ATV320 series, designed for three‑phase synchronous and asynchronous motors. Its compact form factor allows vertical stacking of drives inside machine frames, saving valuable control cabinet space. Designed for Original Equipment Manufacturers (OEMs), it meets simple and advanced application requirements for packaging, material handling, textile, material working, mechanical actuators, and hoisting. Robust design with IEC 60721-3-3 class 3C3 coated printed circuit boards extends machine availability in harsh environmental conditions, with ambient temperatures up to 60°C without additional cooling. Fully integrated with Schneider Electric's EcoStruxure Machine ecosystem via DTM for seamless configuration in SoMove and SoMachine software.
