Schneider Electric ATV320U07N4B AC Variable Speed Drive

Schneider Electric ATV320U07N4B, part of the Altivar 320 family, is a compact three-phase AC variable-speed drive used to control the speed and torque of motors in automated equipment. It delivers 0.75 kW (approximately 1 hp) of output and is rated for a 380–500 V three-phase supply; the U07N4B suffix identifies this exact configuration in a book-type enclosure intended for panel installation. As a member of the Altivar Machine line, it is designed for machine automation applications where high-voltage three-phase power is available. The book enclosure configuration makes it suitable for integration into control cabinets with a compact footprint. This model is commonly specified when a compact, high-voltage VFD is required to drive 3-phase motors in automated processes or machinery in industrial settings. Model code ATV320U07N4B corresponds to a 0.75 kW rating for 3-phase 380–500 V operation in a book enclosure.
