The ABB 3AUD0000004285 is a factory-assembled HVAC drive with an integrated circuit breaker disconnect, built on the ACH580 platform. It is UL-listed for light-overload use at 100 Hp and 99 A output, sized for 500 to 600 V three-phase supplies at 50/60 Hz. That enclosure also carries the disconnect switch, so the drive can be locked out locally for service without opening the panel.
Because the drive integrates the circuit breaker disconnect, it simplifies panel layout and reduces wiring time compared to a separate drive-and-disconnect combination. For a maintenance spares buyer, having one of these in the cabinet means a failed unit can be swapped without re-engineering the branch circuit protection.
