ABB ACH580-31 Ultra-Low Harmonic Drive - UL Type 1/12/3R Enclosure
Part Number: 3AUD0000003547
Quick Summary
The ACH580-31 ultra-low harmonic drive is a precision motor controller designed for HVAC and commercial building systems. It delivers smooth speed control and enhanced energy efficiency across fans, pumps, and conveyors. Facility engineers often contend with harmonic distortion, nuisance trips, and complex bypass configurations during upgrades. This ABB solution addresses those pains with a built-in ABB E-Clipse bypass and an integrated UL (NEMA) Type 1, 12 or 3R enclosure, improving safety and serviceability. With a 1 to 400 hp range at 460 V and a door-mounted control panel that provides a graphical display for local control, it also supports external control connections and serial communications for integrated automation. The result is reliable performance and faster, predictable maintenance cycles.
Product Information
Extended Description
3AUD0000003547 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.
Feature: Ultra-low harmonic design mitigates input distortion, protecting power quality and downstream electrical infrastructure. Business Impact: Reduces transformer loading, lowers utility penalties, and minimizes maintenance costs. Application: HVAC chillers, large fans, and variable-torque pumps where harmonic limits are a concern. Feature: ABB E-Clipse bypass integrated with a bypass motor starter and fast-acting drive fuses. Business Impact: Enables safe, rapid service without full system shutdown, reducing downtime and maintenance windows. Application: Critical HVAC loops and process fans requiring high availability. Feature: Enclosure versatility with UL (NEMA) Type 1, 12 or 3R options and a door-mounted control panel. Business Impact: Simplifies installation, improves safety, and supports compliant cabinet layouts across facilities. Application: On-site retrofit in industrial and commercial control rooms. Feature: Local graphical control panel plus external control connections and serial communications. Business Impact: Accelerates commissioning, provides on-site diagnostics, and enables seamless integration with automation networks. Application: Factory floors and building management systems. Feature: 1 to 400 hp capability at 460 V. Business Impact: Scales with diverse loads, allowing standardization of drives across multiple equipment classes and reducing spare-part diversity. Application: Variable-speed drives for fans, pumps, and conveyors. Feature: Electronic motor overload protection. Business Impact: Protects motors from short-term or sustained overloads, extending motor life and reducing unscheduled downtime. Application: High-load HVAC belts, pumps, and fans with varying torque.

FAQs
Install the ACH580-31 in a suitable UL (NEMA) Type 1/12/3R enclosure, connect the 460 V supply to the drive, and utilize the door-mounted control panel for local setup. The ABB E-Clipse bypass and integrated bypass starter with fast-acting fuses simplify wiring and allow safe, rapid service without full system shutdown. Ensure external control connections and serial communications are configured per the install guide for proper integration with the building management system.
The drive supports 1 to 400 hp at 460 V, employs an ultra-low harmonic design to minimize input distortion, includes electronic motor overload protection, and offers serial communications for network integration. These features collectively improve energy efficiency, reduce electrical stress, and enable smoother, more reliable operation of fans and pumps in HVAC networks.
Yes. Its wide 1–400 hp range, 460 V compatibility, and low-harmonic performance make it ideal for HVAC fans and pumps in commercial buildings, where energy efficiency, reliability, and compatibility with existing automation systems are critical considerations.
The ACH580-31 comes with UL (NEMA) Type 1, 12 or 3R enclosure options, and an integrated ABB E-Clipse bypass. These installation standards support safe operation, compliance with industry codes, and flexible placement in control cabinets or on equipment bays.
Expect reduced downtime due to the integrated bypass and fault isolation, improved motor protection via electronic overload, and easier commissioning through the local graphical display and serial communications. The result is lower maintenance costs, longer motor life, and faster project timelines for upgrading HVAC and related drive applications.
