Product Information
Extended Description
3AUD0000000002 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
Feature → Business Impact → Application: Integrated E-Clipse bypass reduces downtime during maintenance by allowing seamless bypass of the drive while the motor remains aligned and protected, enabling faster service for HVAC fans and pumps. This translates to less interruption during seasonal changes or component swaps in commercial buildings and data centers. Feature → Business Impact → Application: UL-listed protection with a NEMA Type 1, 12 or 3R enclosure simplifies installation in room environments and compliance audits, reducing field wiring concerns and enabling safer enclosure deployment in plant or office HVAC rooms. Feature → Business Impact → Application: Bypass starter and input disconnect/circuit breaker with door interlock provide safe, padlockable OFF, mitigating accidental startups and improving employee safety during maintenance on large fans and compressors. Feature → Business Impact → Application: Electronic motor overload protection guards motors against faults, lowering unplanned downtime and extending motor life in high-load HVAC drives. Feature → Business Impact → Application: Door-mounted control panel with graphical display and serial communications enhances diagnostics, remote monitoring, and quick fault isolation, supporting modern building management system integration and reduced service time.

FAQs
The ACH580 with E-Clipse bypass is designed for UL-listed environments and supports 230/460/575 V power. Ensure the enclosure is installed as a Type 1, 12 or 3R solution per NEMA guidelines, with the door interlocked disconnect or circuit breaker in OFF position during wiring. Verify external control connections and serial interface compatibility with the building management system for seamless integration.
The E-Clipse bypass provides a mechanical bypass path so the motor can continue to operate during drive maintenance or fault isolation. This reduces downtime by allowing bypassed operation without reconfiguring wiring or control logic, enabling quicker service on HVAC fans and pumps while maintaining system reliability and protection.
Yes. The ACH580 supports a wide horsepower range from 1 to 350 hp and operates at standard HVAC voltages of 230, 460, or 575 V. This makes it appropriate for small to medium fans, pumps, and compressors in commercial and industrial HVAC systems, with scalable protection and control features integrated into a single packaged solution.
The ACH580 with E-Clipse bypass is UL-listed and designed for NEMA Type 1, 12 or 3R enclosures. These ratings support safe installation in typical HVAC rooms and harsh environments, with a door-mounted control panel and interlocked disconnect improving electrical safety and compliance with industry standards.
Key benefits include electronic motor overload protection reducing motor stress, a bypass starter for rapid maintenance, and a graphical display for local diagnostics plus serial communications for remote monitoring. Together, these features shorten service windows, lower repair costs, and deliver improved energy efficiency and overall return on investment for HVAC capital projects.
