The 3AXD50000462438: This is the ABB ACS580-0P-075A-2, a 3-phase LV AC packaged drive with a built-in disconnect means, sized for a 25 hp motor under light-overload duty (74.8 A output) or 20 hp under heavy-duty use (59.4 A output) at a 208 to 240 V input. Frame R4, IP21, NEMA Type 1 enclosure — it's a self-contained unit ready for panel or standalone mounting.
The two duty ratings matter: light-overload (25 hp / 74.8 A) is for fans, pumps, and centrifugal loads where the peak demand is brief; heavy-duty (20 hp / 59.4 A) covers constant-torque loads like conveyors or extruders that pull full current continuously. If your motor nameplate says 25 hp but the load is a positive-displacement pump, you need the heavy-duty line — and this drive still fits at 20 hp. The disconnect means integrated into the package saves a separate safety switch, which simplifies panel wiring and reduces enclosure size.
