The ABB 3AUD0000004287 is a packaged HVAC drive from the ACH580 series, combining a variable-frequency drive with an integrated circuit breaker disconnect in a single NEMA 3R enclosure. It's rated for 125 Hp light-overload use per UL, delivering 125 A output current on a 500-600 V three-phase supply at 50/60 Hz.
NEMA 3R means the enclosure is rainproof and sleet-resistant — suitable for outdoor rooftop or wall-mount installations where the drive sees weather but not hose-down. The integrated circuit breaker disconnect eliminates the need for a separate disconnect switch, saving panel space and wiring labor.
