Drive overview
The ABB 3AUD0000000681 is an R6-frame HVAC packaged ultra-low harmonic drive with an integrated circuit breaker, delivering 77 A continuous output and 60 Hp at 460 V under UL light-overload conditions. Rated for 440–480 V three-phase input at 50/60 Hz, it comes in an IP21 NEMA Type1 enclosure — suitable for indoor panel or machine-mount installations where drip protection and basic dust ingress control are needed.
The 77 A output current at 460 V sets the motor-side rating: this drive handles a 60 Hp induction motor under light-overload duty (typical for fan, pump, and compressor profiles in HVAC). Frame size R6 defines the mechanical footprint, mounting hole pattern, and bus-bar interface — critical for retrofit into an existing panel cutout or for ordering the correct wall-mount bracket.
Enclosure and deployment
The built-in circuit breaker reduces external component count and wiring, saving DIN rail space in the motor control center.
