ATV320U55N4B Altivar Machine ATV320 5.5kW Book AC Drive 380‑500V | Schneider Electric

The Original New Schneider Electric ATV320U55N4B 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 book form factor enables space‑optimized vertical stacking in automation cabinets, reducing panel footprint while delivering high power density for demanding OEM and industrial automation applications. Featuring coated printed circuit boards (IEC 60721-3-3 class 3C3), it extends machine availability in harsh environments up to 60°C without additional cooling. Designed for Original Equipment Manufacturers (OEMs), it meets simple and advanced application requirements for packaging, material handling, textile, material working, mechanical actuators and hoisting. Fully integrated with Schneider Electric's EcoStruxure Machine ecosystem via DTM for seamless configuration in SoMove and SoMachine software.
