The ABB 3AUD0000000700 is an ACH580-series HVAC packaged ultra-low harmonic drive with a non-fused disconnect built in. It's a 3-phase unit rated 440-480 V input, delivering 50 Hp light-overload output (65 A) per UL listing. Frame size R6, NEMA Type 1 enclosure, IP21 protection — so it's a ventilated indoor cabinet mount, not a washdown or outdoor unit.
That means ABB still manufactures it, no end-of-life notice on the books. No successor order code has been issued — this is the current production part.
The 65 A light-overload rating (50 Hp at 460 V) is the continuous current the drive can deliver for variable-torque HVAC loads — fans, pumps, compressors. That's the number to match against your motor FLA. The non-fused disconnect built into the package means you don't need a separate disconnect switch upstream; it's a single-cabinet solution for HVAC skids. NEMA Type 1 enclosure is indoor use only — no rain, no hose-down. IP21 adds drip protection but not dust or submersion. Mount it in a conditioned electrical room or a ventilated mechanical penthouse, not on a roof or washdown floor.
Frame size and integration
Frame size R6 defines the physical footprint, mounting hole pattern, and bus-bar layout. That's the dimension that matters for panel cutouts and for ordering the correct bypass or input filter kit — R6 is a known ABB frame across the ACH580 family, so accessories cross over cleanly.
