Product Information
Extended Description
3AUA0000225797 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 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
E-Clipse bypass with an integrated bypass starter enables safe, rapid bypass during maintenance and commissioning, reducing equipment downtime and enabling easier changeovers for HVAC fans and pumps. This translates to lower maintenance costs and improved system availability in critical air-handling applications. The door-mounted control panel provides local diagnostics and control, delivering faster commissioning, simplified troubleshooting, and reduced field service time when addressing fan or pump faults in tight mechanical rooms. The built-in input disconnect switch or circuit breaker with an interlocked door enhances safety and lockout/tagout compliance, helping facilities meet regulatory requirements while preserving a compact control footprint. With a scalable 1 to 350 hp range and 230/460/575 V compatibility, the ACH580 supports a wide spectrum of HVAC loads, minimizing spare parts and accelerating project timelines. Electronic motor overload protection guards motors from overload and fault conditions, lowering failure rates and extending motor life across variable-speed HVAC drives. Serial communications capability and external control connections enable seamless integration with modern BMS and SCADA systems, supporting remote monitoring, fault reporting, and coordinated control strategies for energy optimization. UL-listed protection and NEMA Type enclosure compatibility ensure reliable operation in diverse installations, while the E-Clipse bypass reduces drive losses during bypass operations, contributing to overall system efficiency and reduced life-cycle costs.

FAQs
Installation begins with confirming voltage compatibility (230/460/575 V) and horsepower rating (1 to 350 hp) for your fan, pump, or compressor load. Connect the drive to the motor, install the E-Clipse bypass assembly, and attach the door-mounted control panel. Ensure the input disconnect or circuit breaker is interlocked and padlockable OFF for safety before energizing. Follow ABB wiring guides for field connections and initialize the drive using the local display to verify operation and protection settings.
The ACH580 supports a wide voltage range of 230/460/575 V with a horsepower span from 1 to 350 hp and current ratings up to 34 A for the 25 hp configuration. It includes electronic motor overload protection, a bypass starter, and a door-mounted control panel. This combination enables flexible sizing, robust motor protection, and straightforward wiring in HVAC installations.
Yes. The ACH580 is designed for HVAC applications, including fans, pumps, and compressors found in commercial buildings. Its E-Clipse bypass, integrated protection, and serial communications support enable efficient control, energy savings, and easy integration with building management systems. The enclosure options (UL/NEMA Type 1, 12, 3R) provide installation versatility across different facility environments.
The ACH580 offers UL listing and enclosure compatibility with NEMA Type 1, 12, or 3R configurations, ensuring code-compliant and safe installation in diverse settings. The built-in electronic overload protection and door-interlocked disconnect/breaker further support compliance, maintenance safety, and reliable operation in both new builds and retrofit projects.
The E-Clipse bypass enables quick, safe bypassing of the drive for maintenance or service without rewiring, reducing downtime and service time. It also minimizes heat and losses during bypass operations and simplifies commissioning. Over the system life, this translates to lower maintenance costs, shorter uptime incidents, and a faster return on investment for HVAC projects.
