It runs on 380-480 V three-phase input, frequency range 47.5-63 Hz, and carries IE2 efficiency. Frame size R6, IP20 enclosure, NEMA Open Type. ## Key Ratings & Fit The normal-use current of 145 A (75 kW) is the figure to size branch protection and cabling against. Light-overload use allows 138 A continuous — useful for constant-torque HVAC loads like fans and pumps that rarely hit peak. The 380-480 V input covers common global low-voltage mains; the 47.5-63 Hz frequency tolerance handles weak grids or gen-set supply. ## Integration Notes Wall-mounted, IP20 — install in a clean, dry enclosure. Frame size R6 determines the mounting footprint and gland-plate dimensions; verify panel cut-out against the installation manual before drilling. The IE2 efficiency class meets current minimum standards for most HVAC applications.","metaTitle":"ABB 3ABD00046938-D ACH531-01 HVAC Drive, 75 kW, 145 A, IP20","metaDescription":"ABB 3ABD00046938-D ACH531-01 wall-mounted HVAC drive, 75 kW normal use, 145 A, 380-480 V 3-phase, IP20, IE2, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Frame Size":"R6","Frequency (f)":"47.5 ... 63 Hz","Mounting Type":"Wall-mounted","WEEE Category":"Product Not in WEEE Scope","lifecycle_stage":"current","Efficiency Level":"IE2","Number of Phases":"3-phase","Enclosure Type NEMA":"Open Type","Input Voltage (Uin)":"380 ... 480 V","Degree of Protection":"IP20","Output Power, Normal Use (Pn)":"75 kW","Output Current, Normal Use (In)":"145 A","Output Power, Light-Overload Use (PlD)":"75 kW","Output Current, Light-Overload Use (IlD)":"138 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.abb.com/global/en/products/3abd00046938-d","alternativesUrl":"https://aoctrl.com/api/mcp/products/3ABD00046938-D/alternatives.json"},"ai":{"faq":[{"question":"What are the key electrical ratings for this drive?","answer":"Normal-use output is 75 kW at 145 A; light-overload output is 75 kW at 138 A.
