HVAC ultra-low harmonic drive with integrated circuit breaker
The ABB 3AUD0000000712 is an ACH580-series enclosed ultra-low harmonic drive, purpose-built for HVAC applications. It integrates a circuit breaker and is rated for 5 Hp light-overload use at 7.6 A output current on a 460 V supply (UL listing). Input voltage range is 440-480 V three-phase at 50/60 Hz, making it suitable for North American 460 V and 480 V line feeds common in commercial building HVAC plants. The R3 frame size and NEMA Type 1 / IP21 enclosure mean it is designed for indoor panel or wall-mount installation — no weatherproofing, but adequate for a mechanical room or electrical closet where the drive is protected from direct washdown.
