The ABB 3AUD0000004283 is a packaged HVAC drive with an integral circuit breaker disconnect, UL-classified for light-overload duty at 5 Hp and 6.1 A output. This is a North-American-market variant of the ACH580 platform, pre-configured for pump and fan applications where a separate disconnect saves panel space.
The 5 Hp light-overload rating at 6.1 A is the UL-listed continuous output for variable-torque loads like fans and centrifugal pumps. Light-overload (typically 110% for 60 s) is the standard duty cycle for HVAC — you don't get the 150% heavy-overload headroom a conveyor drive would carry, so don't spec this for a positive-displacement compressor or a crusher. The 500-600 V input range covers 480 V and 575 V nominal systems common in North American industrial plants; the 50/60 Hz rating means the drive handles both line frequencies without a hardware change.
Enclosure and installation context
NEMA Type 3R means this drive lives outdoors — on a roof, an exterior wall, or a pad — without needing a separate weather hood. The circuit breaker disconnect integrated into the chassis eliminates the external fused-disconnect and the interlock wiring, which simplifies the line-side connection for a panel builder. Mounting is typically wall or pedestal; the enclosure is lockable for LOTO compliance.
