Part Number: 3AUA0000039644
Quick Summary
ABB ACS320-03U-02A6-2 is a compact HVAC microdrive designed to optimize pump and fan performance. Engineers often wrestle with energy waste, inconsistent speeds, and integration headaches when tying variable-speed drives into building management systems. UL-listed safety certification supports reliable operation, while embedded BACnet MS/TP enables seamless integration with modern BMS, and 230 V mains for straightforward installation. This combination delivers energy-efficient control, a compact footprint, and reliable compatibility that can reduce downtime, maintenance cycles, and procurement costs across commercial HVAC projects.
Product Information
Extended Description
3AUA0000039644 ABB: The compact ACS320 will save energy throughout your pump and fan HVAC applications. From booster pumps, exhaust and condenser fans to supply and return fans, the drive=E2=80=99s built-in HVAC features such as embedded BACnet (MS/TP) ensure easy and complete integration into building management systems.
Built-in HVAC features enable precise fan and pump control, reducing start-up surges and energy waste. This translates to measurable energy savings and quieter operation in office towers and industrial facilities. In practice, it simplifies commissioning because BACnet MS/TP communication is embedded for direct integration with modern building management systems. With a compact 0.5 HP capacity at 230 V and 4.7 A, the ACS320 provides scalable speed control for booster pumps and exhaust or condenser fans without over-specifying equipment. The result is lower installed cost and better motor protection at part-load conditions. The small footprint fits cramped motor enclosures and retrofits in existing HVAC racks, while plug-and-play wiring speeds up installation alongside standard 230 V distribution. ABB's microdrive ecosystem supports straightforward maintenance and spare-parts availability, reducing downtime when service is required. The device also helps meet energy codes and efficiency programs by delivering precise speed control and reduced waste. Common objections about reliability are addressed by UL-listed safety features, robust protection against short-circuits and overcurrents, and built-in diagnostics that alert technicians before faults escalate.

FAQs
Begin by selecting a stable mounting surface and ensuring proper vibration isolation. Connect the 230 V supply and motor leads according to the wiring diagram, then attach control signals and BACnet MS/TP wiring as required. Parameterize motor type, rated power, and acceleration/deceleration times, then run a commissioning test to verify run-time, current draw, and protective functions before service.
The unit is rated at 0.5 HP output, 230 V input, and draws about 4.7 A under load. It carries UL-listed safety certification and includes embedded BACnet MS/TP for integration with building management systems. It is designed for HVAC pump and fan applications and supports typical 50/60 Hz operation in commercial environments.
Yes. The 0.5 HP, 230 V, 4.7 A specification supports small to mid-size booster pumps and various exhaust or condenser fans. Its precise speed control helps match load to demand, reducing energy consumption and wear. Built-in BACnet MS/TP simplifies integration with existing BMS, enabling coordinated control in complex HVAC systems.
The ACS320-03U-02A6-2 incorporates UL-listed safety certification, indicating adherence to recognized safety standards for electrical devices. For European and other markets, verify CE conformity per local regulations. Certification helps ensure safer operation, smoother regulatory approval, and easier maintenance planning when integrating the drive into HVAC installations.
Expected benefits include reduced energy consumption from precise speed control, extended motor life due to smoother starts and stops, and lower maintenance downtime thanks to built-in diagnostics. The embedded BACnet MS/TP interface streamlines integration with your BMS, speeding commissioning and reducing wiring and procurement costs over the asset’s lifecycle.
