ABB 3AUA0000225784 HVAC Packaged Drive - E-Clipse bypass
Part Number: 3AUA0000225784
Quick Summary
ACH580 HVAC drive optimizes motor control for building HVAC systems. Engineers often struggle to integrate bypass functionality, safety interlocks, and reliable remote control in compact enclosures. This solution is UL listed and available with NEMA Type 1, 12 or 3R enclosures, offering integrated bypass with fast-acting fuse protection and door interlocks. By combining ease of installation with robust protection, it reduces commissioning time and downtime while delivering predictable performance for commercial and industrial HVAC projects.
Product Information
Extended Description
3AUA0000225784 ABB: The ACH580 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 350 hp at 230/460/575 V. The ACH580 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.
The ACH580’s integrated E-Clipse bypass delivers a bypass motor starter within the drive assembly, simplifying maintenance and reducing downtime during motor changes or tests. This translates to faster commissioning and safer belt or gear changes in air handling units and large HVAC installations. The drive can include an input disconnect switch or a circuit breaker with fast acting drive fuses, enhancing safety and enabling secure lockout during maintenance while supporting compliant shutdowns. A door-mounted control panel with a graphical display enables local control and quick fault diagnosis, reducing onsite service calls and accelerating troubleshooting. Serial communications capability and provisions for external control connections ease integration with building management systems, PLCs, and automation networks. With 1 to 350 hp at 230/460/575 V, and UL/NEMA Type 1/12/3R enclosure options, the solution fits retrofit and new-build HVAC equipment with broad compatibility.

FAQs
The ACH580 integrates with building management systems via serial communications and external control connections, allowing seamless integration with PLCs and BAS networks. It supports standard control signals, local menu configuration on the door-mounted display, and can be wired for either a dedicated input disconnect or circuit breaker, enabling simple upgrades without extensive cabinet modification.
The drive provides UL-listed protection and is available in UL (NEMA) Type 1, 12 or 3R enclosure configurations. It includes fast-acting drive fuses, an interlocked door switch, and a padlockable OFF position, delivering safe maintenance and compliant shutdown procedures suitable for commercial and industrial HVAC environments.
Yes. With a horsepower range from 1 to 350 hp and voltages of 230/460/575 V, the ACH580 accommodates a wide array of AHU motors. Its integrated bypass, compact enclosure, and local control panel simplify retrofits by reducing cabinet space needs and enabling quick commissioning without extensive rewiring.
Users typically see improved energy efficiency through precise motor control, reduced mechanical wear from soft starts and smooth speed transitions, and lower downtime due to the integrated bypass and diagnostic display. The electronic overload protection further helps guard motors against overload conditions, extending motor life and reducing maintenance costs.
Although initial costs may be higher than basic drives, the ACH580’s integrated bypass, robust protection, and built-in control capabilities reduce installation time, spare part requirements, and maintenance visits. Long-term savings come from energy efficiency, higher system uptime, and easier compliance with safety standards and building codes.
