The ABB 3AUD0000001553 is a packaged ultra-low harmonic drive for HVAC duty — the sort of unit you spec when the building engineer wants to keep THDi under 5% without a separate filter cabinet. It ships with the circuit breaker integrated, so it wires up clean on the line side: one incoming feed, one set of motor leads out. The UL light-overload rating lands at 150 Hp, 180 A continuous on a 460 V three-phase supply, meaning it handles the bulk of a medium commercial chiller or air handler without derating.
Frame and enclosure
Frame R8 tells the panel builder the footprint and the bus-bar spacing. The enclosure is IP21 with a NEMA Type 1 rating — indoor installation, no washdown, but fine for a mechanical room or rooftop mezzanine where the drive needs a knock-out for conduit entry.
Line power and frequency
Rated for 440 to 480 V three-phase at 50 or 60 Hz — common across North American and global 50 Hz installations. The wide input window means it holds regulation through the typical brown-out sag you see on a shared transformer feeding multiple VFDs.
