The 3AUD0000003812 is an ABB HVAC drive in the R9 frame, rated 300 Hp light-overload at 460 V with 361 A output current. It takes 380-480 V three-phase input at 50/60 Hz and ships in a NEMA 1 enclosure with IP21 protection. The drive is built for pumps, fans, and compressors in commercial buildings. The built-in circuit breaker disconnect saves panel space and wiring time. The R9 frame is a floor-standing cabinet, not a wall-mount. Plan for a concrete pad or heavy-duty floor stand — this isn't something you hang on a unistrut.
Lifecycle status is Active — this is a current-production catalog item, not a phase-out or NRND.
The R9 frame requires a floor-mount footprint. The IP21 enclosure relies on free convection, not forced fans. Input power lands on the integrated circuit breaker disconnect, which doubles as a service-disconnect means. Output terminals are sized for 500 MCM cable per 361 A. The 50/60 Hz rating means it handles both 50 Hz and 60 Hz supplies without derating — useful if you're commissioning on a backup generator or across a 50 Hz site.
