FAQs
Installers should plan for a 460 V power supply, space for the UL-listed enclosure, and proper cable routing to the door-mounted control panel. Include the option for a disconnect switch or circuit breaker and ensure fast-acting drive fuses are correctly sized. Verify interlock functionality for safe maintenance and confirm serial communication wiring for plant integration.
The ACH580-31 employs an ultra-low harmonic drive design with E-Clipse bypass to minimize input current distortion, reducing motor heating and improving power quality. The result is lower energy losses, extended motor life, and reduced electrical stress on feeders—benefiting HVAC fans, pumps, and other variable-speed loads.
Yes. With 1 to 400 hp at 460 V and UL/NEMA enclosure options, the ACH580-31 can replace fixed-speed or older VFDs in many HVAC applications. Its integrated bypass starter and protective features simplify integration with existing control schemes, while serial communications allow seamless PLC/SCADA compatibility during migration.
The drive is UL-listed and designed for UL (NEMA) Type 1, 12, or 3R enclosures, featuring an interlocked, padlockable door switch and a bypass starter. Additional safety comes from electronic motor overload protection, fast-acting fuses, and a robust control panel for local operation, ensuring compliance and safe maintenance.
Expected ROI comes from reduced harmonic currents, lower energy consumption, and decreased motor wear, which translate into energy and maintenance savings. The integrated bypass and comprehensive protection reduce downtime during servicing, while modular compatibility with ABB drives lowers spare-part and training costs over the equipment lifecycle.
