ABB ACH580 Drive - UL/NEMA E-Clipse Bypass System
Part Number: 3AUD0000003727
Quick Summary
ABB ACH580 Drive delivers precise motor control for HVAC systems. This compact, integrated solution simplifies commissioning by combining a bypass starter, an input disconnect, and electronic overload protection in one enclosure. For engineers and technicians, the challenge is often wiring complexity and panel space; the ACH580 reduces both with a door-mounted control panel and a built-in bypass option. The unit is offered with UL/NEMA Type 1, 12, or 3R enclosure configurations, supporting 230/460/575 V and a range of horsepower from 1 to 350 hp. Serial communication capability enables easy integration with existing control networks, delivering faster setup, safer operation, and improved lifecycle costs.
Product Information
Extended Description
3AUD0000003727 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

FAQs
The ACH580 supports 1 to 350 hp motors at 230/460/575 V and can replace or retrofit legacy drives in HVAC equipment. Its integrated bypass, door-mounted control panel, and available UL/NEMA enclosures simplify wiring, reduce panel depth, and streamline safety interlocks. When planning an upgrade, verify motor compatibility, wiring category, and available space for the selected enclosure to ensure a smooth installation.
Ideal applications include HVAC fans and pumps in packaged units, building automation systems, and conveyors where frequent starts occur. The E-Clipse bypass enables a safe bypass path during maintenance, reducing downtime and panel complexity. For retrofit projects, this drive lowers installation time and improves energy efficiency while maintaining protective features such as electronic overload protection.
The ACH580 offers UL (NEMA) Type 1, 12, or 3R enclosure compatibility, with a bypass motor starter and interlocked door mechanisms. These features support safe operation, code compliance, and flexible installation in control rooms, equipment spaces, or outdoor-rated configurations. Ensure the chosen enclosure aligns with local electrical codes and environmental conditions for optimal performance.
The E-Clipse bypass provides a controlled bypass path that allows motor operation to continue or be safely isolated during maintenance. This reduces hot-work risk, minimizes downtime, and simplifies electrical protection coordination. In HVAC applications, it also shortens service windows and improves overall system availability by enabling quicker, safer maintenance cycles.
The ACH580 includes serial communications capability and external control connections, enabling seamless integration with building management systems and industrial networks. This supports remote monitoring, diagnostics, and centralized parameter tuning. For best results, map the drive’s control signals to your PLC or BAS inputs and ensure proper network security and update cadence.
