The ABB 3AUD0000000037 is a factory-assembled HVAC packaged drive integrating an ACH580 variable-speed drive with an e-clipse bypass contactor and a disconnect switch, all inside a NEMA 3R enclosure. That means it arrives ready for outdoor or sheltered wall-mount installation — no separate bypass cabinet or field wiring of the bypass contactor. The 240 A continuous rating at light-overload (UL) corresponds to 200 Hp on a typical 460 V motor, sized for large centrifugal fans, pumps, or cooling towers in commercial HVAC plants.
Voltage, phases, and frequency — what the line needs
Input voltage range is 440 to 480 V, three-phase, 50/60 Hz. That covers the common North American 460 V and 480 V distribution systems as well as 50 Hz grids. The NEMA 3R enclosure protects against rain and sleet but is not rated for hose-down or submersion — suitable for rooftop or exterior wall mounting where the drive sees weather but not washdown.
This is a current-production catalog item, not a phase-out or last-time-buy.
