The ABB 3AUD0000000697 is a HVAC-specific ultra-low harmonic drive from the ACH580 family, carrying a non-fused disconnect switch integrated into the package. It's rated for 25 Hp light-overload UL output at 34 A on a 460 V three-phase supply, with an input voltage window of 440 to 480 V at 50 or 60 Hz. The NEMA Type 1 enclosure (IP21) suits indoor panel or machine-mounted installations where washdown isn't required. Frame R6.
The 25 Hp / 34 A light-overload rating (UL) is the continuous motor current the drive can deliver without derating — sized for a 25 Hp 460 V induction motor driving a fan, pump, or compressor in a typical HVAC duty cycle. Light-overload means 110% current for 60 seconds every 10 minutes; if your load profile requires higher overload (e.g., 150% for extruder starting), this drive isn't the right pick. The 440-480 V input range covers 460 V nominal North American supplies and 400 V European supplies at the high end, but it won't run on 208 V or 240 V. The NEMA 1 enclosure keeps dust and incidental contact out but isn't sealed against hose-down — plan for a clean, dry electrical room or panel.
