HVAC drive with integrated harmonic mitigation
The ABB 3AUD0000003144 is a packaged ultra-low harmonic drive built for HVAC applications. It ships with a non-fused disconnect switch integrated into the enclosure, simplifying panel layout and reducing external component count. Rated for 200 Hp light-overload duty, delivering 240 A continuous output — sized for large fan, pump, and compressor loads in commercial building HVAC plants. Input accepts 440-480 V three-phase at 50 or 60 Hz, covering common North American and global mains voltages without transformer adjustment.
Housed in a NEMA Type 1 enclosure with IP21 ingress protection — suitable for indoor, non-washdown environments like mechanical rooms, rooftop units, and electrical closets. The R11 frame size determines footprint and mounting hole pattern; verify clearance for the integrated disconnect handle swing.
