Product Information
Extended Description
3AUA0000226968 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 HVAC drive integrates ABB E-Clipse bypass, providing a bypass motor starter within a single enclosure to simplify commissioning and service. This feature reduces downtime during maintenance and allows safe, fast isolation of the drive from the load. The enclosure options aligned to UL Type 1/12/3R standards support indoor and outdoor mechanical rooms, improving installation flexibility and code compliance for commercial buildings. Bypass functionality with fast-acting drive fuses and a door-mounted interlocked switch enhances personnel safety and protects equipment during fault events, delivering tangible reductions in maintenance costs. Electronic motor overload protection ensures motor health is monitored continuously, lowering the risk of unexpected failures in critical HVAC applications and enabling proactive maintenance planning. A door-mounted control panel with graphical display enables local commissioning, while external control connections and serial communications capability streamline integration with building automation systems. The drive supports a broad horsepower range from 1 to 350 hp and operates at 230/460/575 V, providing scalable performance for a wide array of fans and pumps. These features collectively improve energy efficiency, reduce installation time, and align with modern BAS interfaces, addressing common objections about retrofit complexity and compatibility with existing electrical infrastructure.
