Product Information
Extended Description
3AUD0000003812 ABB: The ACH580 Packaged Drive includes an ACH580 drive in a UL (NEMA) Type 1, 12 or 3R enclosure with input disconnect switch or circuit breaker, both including fast acting drive fuses. It is available from 1 to 350 hp at 230/460/575 V. The ACH580 Packaged Drive provides a door-mounted input disconnect switch (padlockable in the OFF position), electronic motor overload protection, a door-mounted control panel with graphical display for local control, provisions for external control connections, and serial communications capability.
Integrated input disconnect switch or circuit breaker with fast-acting drive fuses enhances safety and simplifies wiring, enabling quicker lockouts and safer maintenance while reducing installed-hardware costs. Business impact: safer, compliant installations with lower commissioning time; Application: rooftop units, air handlers, and commercial chiller packs. The door-mounted control panel with graphical display delivers local control and quick parameter setup, shortening startup and reducing operator training time. Business impact: faster fault diagnosis and streamlined service; Application: on-site adjustments in mechanical rooms or equipment closets. Electronic motor overload protection guards motors against overloads and nuisance trips, extending motor life and minimizing unplanned downtime. Business impact: improved reliability, lower maintenance costs; Application: elevated duty cycles in large air-moving systems. Wide hp range from 1 to 350 and voltages at 230/460/575 V enable flexible deployment across equipment footprints, improving spare-part alignment and procurement efficiency. Business impact: standardized hardware across multi-equipment fleets; Application: mixed fleets in large buildings. External control connections and serial communications capability simplify integration with building management systems and PLCs, enabling centralized monitoring and remote diagnostics. Business impact: enhanced visibility, predictive maintenance, and potential energy optimizations; Application: BI/SCADA integrations and BMS platforms.

FAQs
Install within a UL-listed Type 1/12/3R enclosure using the door-mounted input disconnect or circuit breaker, and ensure supply matches 230/460/575 V and motor rating from 1 to 350 HP. Connect external controls per the controller’s schematic, enable electronic overload protection, and configure the local control panel for basic run/stop and parameter tuning. Verify serial communications settings for BMS integration.
Key specs include a horsepower range from 1 to 350 HP, voltages of 230/460/575 V, and current capacity up to 361 A for the 300 HP variant ACH580-PCR-361A-4. The drive is packaged with an input disconnect and fast-acting fuses, and provides electronic motor overload protection, suitable for HVAC fans and pumps with reliable protection.
Yes. It is designed for packaged HVAC applications such as rooftop units, air handlers, and chiller packs. The integrated disconnect, local control panel, and external control interfaces support building automation and energy management. Its scalable HP/voltage options enable deployment across a portfolio of equipment while maintaining a consistent control strategy.
The package is UL-listed and offered in NEMA Type 1, 12, or 3R enclosure configurations with a door-mounted disconnect. While CE is not specified in the provided data, the UL listing and enclosure ratings provide strong compliance for many US/Canada HVAC deployments and indoor installations, with protected access and safe de-energization features.
By enabling precise speed control and smoother start/stop cycles, the ACH580 Packaged Drive reduces motor wear and energy waste, contributing to lower operating costs. Integrated protection reduces unplanned outages, while local control and easy integration with BMS/SCADA streamline maintenance planning and diagnostics, improving overall equipment availability.
