ABB publishes two operating points on this code: normal duty at 20 Hp with 27 A output current, and heavy duty at 15 Hp with 21 A output current. The duty split is the figure to match against the load, not the headline nameplate — a constant-torque conveyor or extruder wants the heavy-duty 15 Hp / 21 A envelope, while a fan or centrifugal pump can ride the normal-duty 20 Hp / 27 A point with margin to spare. Supply-side the drive accepts 480 V AC and produces a three-phase output, matching the stated supply range on the data sheet for direct connection to a 480 V US distribution. ## Sizing the motor to the drive On a 480 V three-phase feed, the 27 A normal-duty current figure maps roughly to a 20 Hp four-pole induction motor, and the 21 A heavy-duty figure maps to 15 Hp — those are the two ABB-rated match points and they are the only ones the warranty paperwork will treat as in-spec. If the driven load is constant torque (mixers, compressors, conveyors with high breakaway), spec to the 15 Hp / 21 A heavy-duty point. If the load is variable torque (HVAC fans, centrifugal pumps), the 20 Hp / 27 A normal-duty point carries the motor with thermal headroom and lets a slightly larger motor ride on the same drive. ## Same-family cross-shop The next-step sibling in the ACS580-01 line at 480 V is the ACS580-01-034A-4, listed at 25 Hp on the same three-phase 480 V AC platform. It sits one current step above this code and is a like-for-like swap when the motor on the nameplate is closer to 25 Hp than 20 Hp — same family, same wall-mount NEMA 1 form factor, different output current. ## Panel integration The R3 frame at 8.16\" W and 9.33\" D sets the wall area the panel builder needs to leave clear above and below the unit for heatsink airflow; cabinet cooling should be sized to the drive's own thermal curve rather than the panel's nameplate ambient.","metaTitle":"ABB ACS580-01-027A-4 Drive, 480V 3PH 20Hp","metaDescription":"ABB ACS580-01-027A-4 general-purpose drive, 3-phase, 480 V AC, 20 Hp normal / 15 Hp heavy duty, 27 A / 21 A, wall-mount NEMA 1, frame R3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Type":"General Purpose Drive","Phase":"3","title":"Variable Frequency Drive 3PH, N1, 480V, 15/20Hp|3-Phase Supply Voltage, 380-480V AC, Wall Mount Drive, 3-Phase Output, NEMA 1, Normal Duty: 20 Hp, Heavy Duty: 15 Hp, Normal Duty: 27 Amp, Heavy Duty: 21 Amp, Frame Size: R3: H: 20.93\" W: 8.16\" D: 9.33\"","Volts AC":"480","Horsepower":"20","description":"Variable Frequency Drive 3PH, N1, 480V, 15/20Hp|3-Phase Supply Voltage, 380-480V AC, Wall Mount Drive, 3-Phase Output, NEMA 1, Normal Duty: 20 Hp, Heavy Duty: 15 Hp, Normal Duty: 27 Amp, Heavy Duty: 21 Amp, Frame Size: R3: H: 20.93\" W: 8.16\" D: 9.33\"","Family / Style":"ACS580","lifecycle_stage":"current"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,619.64","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/96625dde7833d08904d4867ef012a85f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the listed type for the ACS580-01-027A-4?","answer":"The listed type is General Purpose Drive on the Motor Drives line, three-phase, 480 V AC, ACS580 family."},{"question":"What is the listed phase for the ACS580-01-027A-4?","answer":"The listed phase is three-phase (3), matching the three-phase output the drive produces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS580-01-027A-4","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/ACS580-01-027A-4 when reusing this data.
