ABB ACS550-01-059A-4 3AUA0000002546-D Frequency Converter

Product Introduction

The ABB ACS550-01-059A-4 (3AUA0000002546-D) is a reliable general-purpose frequency converter designed for stable and efficient AC motor speed control in industrial automation systems. As part of ABB’s ACS550 series, it provides consistent performance, straightforward commissioning, and wide applicability across standard industrial drive applications.

This model supports a three-phase 380–480V input supply and is commonly used in medium-to-heavy industrial systems such as pumps, fans, conveyors, compressors, and process machinery. With a rated output power of 30 kW under normal duty, it is suitable for applications requiring higher torque and stable speed regulation.

The drive is designed for practical industrial use, featuring a user-friendly parameter structure that allows fast setup and easy maintenance. This reduces commissioning time and simplifies integration into both new and existing systems.

Its wall-mounted R4 frame design provides a robust yet space-efficient installation solution for control cabinets. With an IP21 protection rating and NEMA Type 1 enclosure, it is intended for use in clean and controlled indoor environments.

With a frequency range of 47.5–63 Hz and integrated motor protection functions, the ACS550 series helps ensure reliable operation, improved system stability, and reduced downtime in continuous industrial use.
