Product Information
Extended Description
3AUA0000225655 ABB: The ACH580 with ABB E-Clipse bypass has an integrated UL (NEMA) Type 1 enclosure with a bypass motor starter and is available from 1 to 75 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 with E-Clipse bypass combines a compact drive with an integrated bypass starter, enabling quick bypass transitions and reduced downtime during maintenance or service. This directly translates to measurable uptime gains for critical HVAC fans and pumps, improving overall building reliability and service continuity. In practice, contractors can install and commission the system faster, with fewer wiring challenges and a smaller panel footprint. Power range and voltages are designed to cover 1 to 75 HP and operate at 230/460/575 V, providing a scalable solution for a wide range of HVAC fans, air handling units, and rooftop units. This flexibility lowers total cost of ownership by supporting multiple applications without swapping drives. You get a door-mounted control panel with a graphical display for local operation and troubleshooting, plus a robust safety setup including an input disconnect or circuit breaker with fast-acting fuses and a padlockable OFF interlock. This configuration simplifies service, reduces risk during maintenance, and supports compliant, safe panel design. Serial communications capability and provisions for external control connections enable seamless integration with building automation systems (BACnet/Modbus and other BAS interfaces where applicable), enhancing remote monitoring, fault diagnosis, and energy management. Engineers gain better visibility into motor health and energy use, driving smarter maintenance planning. Electronic motor overload protection protects the motor and drive life, reducing nuisance trips and extending equipment longevity in dynamic HVAC loads. With this protection, facilities experience fewer unplanned outages and more consistent performance, which translates to lower repair costs and improved occupant comfort.
