The ABB 3AUD0000003482 is an HVAC drive with an integrated circuit breaker disconnect, rated for 414 A continuous at light-overload duty per UL. The corresponding UL power rating is 350 Hp. It's built for 3-phase 380...480 V supplies at 50/60 Hz. The IP55 enclosure and NEMA Type 12 rating mean the drive is sealed against dust and low-pressure water jets — suitable for indoor installation in washdown areas or HVAC mechanical rooms where hose-down cleaning is routine. The NEMA 12 rating also confirms it's oil- and dirt-resistant for factory-floor placement.
Light-overload (variable-torque) duty at 414 A is the rating that governs selection for fan and pump loads — the drive can deliver full current continuously without derating for the quadratic torque curve of a centrifugal load. For constant-torque (conveyor or compressor) applications, the heavy-overload rating would be lower; this variant is optimized for HVAC duty. The integrated circuit breaker disconnect eliminates the need for a separate upstream disconnect switch, saving panel space and wiring labor.
