What it is and where it sits in the line
The ABB ACS580-01-03A5-4 is a general purpose drive in the ACS580 family, built for 3-phase operation at 480 V AC and rated 2 horsepower in the normal-duty profile. Mechanically it ships as a wall-mount drive in a NEMA 1 enclosure, frame size R1, with the published outline at H 14.69" × W 4.92" × D 8.78" — the small-cabinet footprint of the ACS580 series.
Read the duty pair, not the headline number
The spec carries two current and horsepower figures and the load profile is what picks between them: 4.8 A at 2 Hp on normal duty, 3.4 A at 1.5 Hp on heavy duty. For constant-torque loads — conveyors, positive-displacement pumps, mixers, extruders — the heavy-duty 3.4 A / 1.5 Hp figure is the one that governs the motor selection, and the normal-duty 4.8 A / 2 Hp number is additional headroom for variable-torque fans and centrifugal pumps. Supply-side input is specified across 380-480 V AC, three-phase, with a 3-phase output to the motor; a 480 V three-phase feeder is required on the line side.
Application fit at this frame
An R1-frame 480 V drive in the 1.5-2 Hp class is the typical pick for small industrial pumps, fans, blowers, and light conveyor duty where wall-mounting beside the motor disconnect keeps cable runs short. On cable length, the general rule with 480 V PWM output is to keep motor leads within the drive's published limit and add a dV/dt or sine filter on longer runs — reflected-wave voltage at the motor terminals can exceed insulation limits well before the drive itself flags a fault.
Sourcing posture
Sourcing is handled against an RFQ: quote to order on the BOM line rather than pulling from a generic shelf listing, and flag the exact duty profile (normal vs heavy) so the replacement matches the original application.
