ABB ACS550-01-045A-4 3AUA0000012789-D Frequency Converter

Product Introduction

The ABB ACS550-01-045A-4 (3AUA0000012789-D) is a robust general-purpose frequency converter designed for reliable AC motor speed control in industrial automation environments. As part of ABB’s widely used ACS550 series, it is engineered to deliver stable performance, easy configuration, and consistent operation across a broad range of standard industrial applications.

This model operates on a three-phase 380–480V supply and is commonly applied in systems such as pumps, fans, conveyors, compressors, and general machinery. With a rated output power of 22 kW under normal duty, it provides sufficient capacity for medium-power industrial drive requirements while maintaining stable operational performance.

The ACS550 platform is designed with usability in mind. Its integrated control interface allows fast parameter setup and commissioning, reducing installation time and minimizing engineering complexity. This makes it suitable for both new installations and retrofit projects where efficiency is important.

The wall-mounted R3 frame design ensures compact installation and easy integration into control cabinets. With IP21 protection and NEMA Type 1 enclosure classification, it is intended for use in controlled indoor industrial environments.

With IE2 efficiency performance, the drive helps reduce energy consumption while maintaining reliable motor control. Built-in protection functions improve system safety and reduce downtime in continuous operation scenarios.
