ABB 3AUD0000003574 Motors & Drives - UL 150 HP 180 A 460 V
Part Number: 3AUD0000003574
Quick Summary
ABB ACH580-31 ultra-low harmonic drive provides precise motor speed control for HVAC equipment and general industrial drives, enabling smoother operation and improved energy efficiency. Maintenance teams frequently struggle with harmonic distortion, EMI, and unexpected downtime that disrupt cooling cycles and increase total cost of ownership. This solution features UL (NEMA) Type 1, 12 or 3R enclosure options, integrated E-Clipse bypass, an input disconnect with fast-acting fuses, and interlocked, padlockable access for safe startup and service. A door-mounted control panel with a graphical display supports local control, while external connections and serial communications enable scalable automation architectures across HVAC and manufacturing facilities.
Product Information
Extended Description
3AUD0000003574 ABB: The ACH580-31 ultra-low harmonic drive with ABB E-Clipse bypass has an integrated UL (NEMA) Type 1, 12 or 3R enclosure with a bypass motor starter and is available from 1 to 400 hp at 460 V. The ACH580-31 ultra-low harmonic drive with ABB E-Clipse bypass provides an input disconnect switch or circuit breaker, both including fast acting drive fuses, with door mounted and interlocked switch (padlockable in the OFF position), a bypass starter, electronic motor overload protection, a door mounted control panel with graphical display for local control, provisions for external control connections, and serial communications capability.
Ultra-low harmonic design minimizes current distortion and improves power quality, translating into cooler motors, longer bearing life, and lower EMI in the drive train. This reduces energy waste and helps facilities stay in compliance with power-quality guidelines, with particular benefits for HVAC fans, pumps, and mixed-load conveyors in large facilities. Integrated ABB E-Clipse bypass provides a safe, built-in bypass starter that lets you isolate the drive without interrupting the motor connection. The bypass simplifies maintenance and reduces downtime during service or troubleshooting, supporting quick fault isolation in critical HVAC and process applications. Enclosure options include UL (NEMA) Type 1, 12, or 3R configurations, allowing installation in a range of environments; an interlocked, padlockable door and fast-acting drive fuses on the input disconnect improve safety and compliance during commissioning and maintenance. This packaging also helps reduce enclosure-associated costs by consolidating components. The door-mounted graphical control panel delivers local visibility and configuration, speeding start-up and on-site adjustments. External control connections and serial communications enable seamless integration with building management systems and industrial automation networks, minimizing wiring complexity and supporting scalable deployment across multiple machines. The electronic motor overload protection protects the drive and motor under overload conditions, reducing component wear and unplanned outages. Compatibility with 460 V three-phase power and a 1–400 hp range enables standardization across mixed fleets, supporting predictable maintenance planning and lower spare-part inventories. When integrating with existing automation, the ACH580-31 offers compatible communications options and a 460 V input that aligns with common plant electrical infrastructure, reducing wiring changes and downtime during retrofits. Field-proven in HVAC and process industries, the drive supports standard install practices, avoiding custom cabling and facilitating faster commissioning.

FAQs
Plan for 460 V three-phase power and ensure the drive is sized within the 1 to 400 HP range. Select UL/NEMA Type 1, 12 or 3R enclosure, install the input disconnect or circuit breaker with fast-acting fuses, and incorporate the E-Clipse bypass. Mount the door-mounted control panel and configure serial communications if remote monitoring is required.
The ACH580-31 is an ultra-low harmonic drive designed to minimize harmonic distortion and EMI while delivering precise speed control. Key specs include 460 V operation, up to 180 A input current, 1–400 HP range, integrated bypass, electronic motor overload protection, and serial communications capability for integration with automation networks.
The drive is available in UL (NEMA) Type 1, 12 or 3R enclosure configurations, intended for indoor or protected environments. There is no explicit hazardous-location rating listed; for explosive atmospheres or special regulatory requirements, consult ABB for alternative variants or additional protective enclosures.
The integrated E-Clipse bypass allows the motor to continue operation while the drive is isolated for maintenance, enabling quicker fault isolation and servicing. It minimizes project downtime, simplifies testing, and reduces wiring changes during preventive maintenance or component replacements.
Benefits include reduced energy consumption from improved power quality and lower EMI, fewer unplanned outages due to electronic overload protection, and streamlined commissioning with local and remote control options. Standardizing on 460 V, 1–400 HP fleets also lowers spare parts diversity and simplifies maintenance planning across facilities.
