Schneider Electric ATV320U40N4B Altivar Machine ATV320 is a 4 kW (5 HP) three-phase variable frequency drive built in a compact book-form enclosure (IP20) for easy panel integration. It accepts a 3-phase 380–500 V AC supply and provides precise motor speed control for automation tasks requiring smooth start and stop, ramping, and reliable protection on standard three-phase motors. As part of the Altivar 320 family, this model is designed for machine builders and system integrators needing a compact, reliable VFD for 4 kW output in a 380–500 V, three-phase system. The book-form design saves panel space and supports straightforward wiring and mounting in cabinets, while Schneider Electric's engineering heritage underpins compatibility with common control schemes and safety practices. This variant is specified for 4 kW output, 380–500 V input, three-phase operation, and IP20 protection, making it suitable for new installations or retrofits where compact motor control is required in industrial environments.
