ABB 3AUD0000000008 Motors & Drives - UL E-Clipse Bypass
Part Number: 3AUD0000000008
Quick Summary
3AUD0000000008 is a ABB HVAC packaged drive with an integrated E-Clipse bypass for reliable motor control in commercial and industrial HVAC systems. Engineers often face downtime during bypass maintenance, confusing wiring, and space constraints in equipment rooms. This solution emphasizes UL-listed protection and a NEMA Type 1/12/3R enclosure, plus a door-mounted control panel and electronic motor overload protection to simplify startup and fault handling. The design reduces wiring complexity and commissioning time while delivering consistent performance. By supporting scalable horsepower ranges and both local and remote control options, it aligns with modern building-automation goals and drives measurable improvements in efficiency and total cost of ownership.
Product Information
Extended Description
3AUD0000000008 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
Integrated E-Clipse bypass with bypass motor starter streamlines service workflows, reducing downtime during maintenance and bypass transitions while maintaining motor protection and safe isolation. This feature improves maintenance planning and asset availability in critical HVAC equipment such as rooftop units and air-handling systems. The enclosure is UL-listed with NEMA Type 1/12/3R options and includes a door-mounted control panel, enabling safer, plug-and-play installations and easier on-site commissioning in tight equipment rooms. A built-in input disconnect switch or circuit breaker (padlockable in the OFF position) enhances safety compliance and lockout/tagout practices during service windows. Electronic motor overload protection manages motor health proactively, minimizing overheating risk and extending motor life in demanding HVAC drives. Serial communications capability and external control connections support modern automation architectures and remote monitoring, reducing field service calls and enabling data-driven maintenance planning.

FAQs
The drive is designed for HVAC applications with a UL-listed NEMA Type 1/12/3R enclosure and a door-mounted control panel. Installers should plan for safe access to the padlockable OFF switch, ensure correct 230/460/575 V supply, and verify external control connections and serial communications capabilities to enable seamless integration with existing building automation systems.
E-Clipse bypass provides a controlled bypass path, allowing motor servicing without full power-down of the drive circuit. This reduces downtime for routine maintenance and fault isolation, simplifies bypass transitions, and improves equipment availability in HVAC systems with tight uptime requirements.
Yes. The ACH580-based platform includes serial communications capability and provisions for external control connections, enabling integration with ABB automation ecosystems and common building-management protocols. This compatibility supports centralized monitoring, remote diagnostics, and unified asset management across multiple drives.
The drive adheres to UL-listed requirements with EN/NEMA-compliant enclosure options (Type 1/12/3R) and includes a padlockable OFF disconnect for safe maintenance. While CE markings and IP ratings depend on regional configurations, the standard-focused design emphasizes electrical protection, safe operation, and reliable performance in HVAC environments.
By reducing maintenance downtime, protecting motor health with electronic overload protection, and enabling safer, quicker commissioning, the 3AUD0000000008 can lower field service costs and energy waste. Its scalable horsepower range and compatibility with building-automation interfaces support energy-efficiency initiatives and longer asset lifecycles, delivering tangible total-cost-of-ownership improvements.
