Product Information
Extended Description
3AXD50000646968 ABB: The cabinet-optimized ACH480 drive has complete HVAC functionality to control fans, pumps, compressors, and more complex HVAC equipment like air-handling units, ensuring smooth, energy-efficient operation of your HVAC systems in normal and mission-critical situations. The built-in features significantly reduce installation time and the intuitive control panel with an HVAC-specific primary settings menu and help assistants makes startup, commissioning and operation easy. The optional Bluetooth=C2=AE capability enables the commissioning and monitoring of the drive from a distance. The ACH480 is especially a good fit for panel builders and OEMs.
Feature: Cabinet-optimized ACH480 drive includes HVAC-specific control algorithms that directly impact energy use, enabling precise motor speed regulation for fans, pumps and compressors. Business impact: reduced energy consumption and lower operating costs across HVAC systems. Application: ideal for air-handling units, rooftop units and complex packaged systems in commercial buildings. The second feature is an intuitive HVAC-focused primary settings menu with embedded help assistants, which speeds commissioning, minimizes setup errors, and supports repeatable configurations for multiple installations. The business impact is faster project delivery, fewer commissioning delays, and more consistent performance across sites. Third, the optional Bluetooth capability enables remote commissioning and monitoring, reducing on-site visits and enabling proactive maintenance. The business value is improved asset uptime and lowered service costs. Fourth, the drive delivers 0.75 kW at 200 V with 4.8 A, making it well-suited for medium-load HVAC equipment and panel-mounted installations. Application-wise this supports energy-efficient control for fans, pumps, and small compressors. Fifth, built-in diagnostics and protection features enhance reliability and simplify troubleshooting, translating to reduced maintenance overhead for OEMs and integrators. Finally, compatibility with ABB control ecosystems and OEM harnesses accelerates integration with building management systems and scalable, retrofit-friendly installations.

FAQs
ACH480-04-04A8-2 is designed for cabinet mounting in HVAC control panels. Plan for proper enclosure protection, adequate cooling, and clean wiring routes to minimize heat buildup and electrical noise. Use standardized motor starter wiring practices, ensure correct line voltage configuration (200 V), and integrate with panel-mounted sensors and BMS inputs to maximize reliability and ease of maintenance.
The drive provides precise speed control for HVAC motors, enabling ramping, ramp-down, and vector control algorithms tailored to fans, pumps, and compressors. This reduces peak current, lowers processor loads during startup, and optimizes fan/pump curves for steady-state efficiency. The result is lower energy bills, reduced mechanical wear, and extended equipment life across HVAC systems.
Best applied to air-handling units, rooftop units, variable-air-volume fans, circulating pumps, and small compressors within commercial buildings. Its cabinet-optimized form factor and HVAC-specific settings simplify integration in panel-based installations and retrofit projects, making it a strong choice for OEMs and system integrators targeting energy-efficient building automation.
The ACH480-04-04A8-2 is designed to meet common European regulatory expectations with CE-like compliance for HVAC drives. For mission-critical installations, verify the exact certifications applicable to your region and project requirements with your ABB distributor, and request documentation for enclosure protection and safety approvals as part of your procurement package.
ROI comes from lower energy consumption due to precise motor control and reduced maintenance through built-in diagnostics and remote monitoring options. With faster commissioning via HVAC-specific menus and optional Bluetooth for remote checks, technician visit frequency decreases, resulting in lower service costs and faster project completion for new builds or retrofit programs.
