The ABB 3AUD0000003573 is an ACH580-series HVAC enclosed ultra-low harmonic drive, factory-fitted with a circuit breaker. It delivers 100 Hp continuous output under UL light-overload duty, drawing 124 A at 460 V. The R8 frame houses a 3-phase input section rated for 440... 480 V, 50/60 Hz. The IP21 and NEMA Type 1 enclosure suits indoor installation in mechanical rooms or equipment closets — no washdown exposure, but adequate for dry HVAC plant environments. The integrated circuit breaker simplifies panel wiring by combining drive and branch-circuit protection in one footprint.
The 100 Hp / 124 A light-overload rating is the UL-listed continuous output for a typical HVAC load profile — fans, pumps, compressors running below 110 % rated current. The 440... 480 V input range covers 460 V nominal supplies common in North American industrial plants. The R8 frame size determines mounting hole pattern, gland-plate entry, and overall cabinet depth; verify the existing enclosure has the clearance before committing the BOM line.
Installation context
Mount the drive on a flat vertical surface inside the NEMA 1 enclosure; allow minimum clearance above and below for airflow per the ACH580 installation manual. The integrated circuit breaker serves as the disconnecting means — no separate branch breaker needed upstream if the SCCR rating matches the available fault current. Wire the 3-phase input through the gland plate; torque lugs to the values stamped on the bus bar.
