ACS550-01-04A1-4 1.5kW Standard Drive 380-480V IP21 | ABB

The Original New ABB ACS550-01-04A1-4 is a 1.5 kW (2 HP) general-purpose wall-mounted AC drive from the ACS550 series, designed for reliable motor control across a wide range of industrial applications. Rated at 4.1 A normal duty (3.3 A heavy duty) with a 380–480 V three-phase input, this drive delivers efficient speed and torque control for pumps, fans, conveyors, compressors, mixers, and other variable and constant torque applications. Featuring an IP21 enclosure, integrated EMC filter (Category C2), built-in Modbus RTU communication, and sensorless vector control, the ACS550-01-04A1-4 simplifies installation and reduces the need for external components. Its robust design with coated circuit boards makes it suitable for demanding industrial environments across multiple sectors, including HVAC, water treatment, food and beverage, and material handling.
