UL-listed with optional NEMA Type 1, 12 or 3R enclosures ensures compliant, safe installations in demanding environments. The ACH580-31 integrates a bypass starter and a door-mounted graphical control panel for straightforward local operation. With scalable 1–400 hp performance at 460 V, these drives cut energy use, simplify commissioning, and reduce maintenance in modern HVAC plants.
Product Information
Extended Description
3AUD0000003149 ABB: The ACH580-31 ultra-low harmonic drive 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 400 hp at 460 V. The ACH580-31 ultra-low harmonic drive 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.
Ultra-low harmonic control built into the ACH580-31 reduces THD and improves power quality. This lowers motor stress, extends bearing life, and reduces energy waste across the drive system. Ideal for HVAC fans and pumps where variable-speed operation creates harmonics that degrade efficiency and reliability. ABB E-Clipse bypass enables an integrated bypass path for maintenance without stopping the process. Minimizes downtime and simplifies troubleshooting by letting the motor continue operation while the drive is serviced. Reliable for large air handlers and rooftop unit deployments in busy facilities. Enclosure options UL (NEMA) Type 1, 12, or 3R protect the drive in indoor and mild outdoor environments. This protection minimizes enclosure corrosion and dust ingress, reducing service calls and part replacements. Suitable for indoor plant rooms and outdoor equipment mounting near HVAC equipment. Input disconnect switch or circuit breaker with fast-acting drive fuses improves safety and regulatory compliance during installation and maintenance. This supports safer maintenance windows and adherence to electrical codes. Works well in connected building automation setups. Door-mounted control panel with graphical display enables local monitoring and quick fault diagnosis. Operators can tune parameters efficiently, reducing field service time and improving first-time fix rates. Ideal for on-site commissioning of HVAC drives in hospitals, factories, and campus buildings. Serial communications capability and external control connections enable seamless integration with Building Management Systems. This enables remote monitoring, energy analytics, and preventative maintenance scheduling. Compatible with standard BACnet/Modbus networks used in modern facilities.
