Stall prevention is programmable from 20 to 250% of rated current, letting the integrator tune how aggressively the drive folds back speed before tripping on a stall — the upper end covers the high-inertia start of a large fan or mixer without nuisance trips. Three skip-frequency zones are settable across 0.1–400 Hz — the tool used to keep the drive's output frequency out of the mechanical resonance bands of the driven load, which matters on pumps and fans where resonant vibration will eat bearings if the drive is allowed to dwell on the resonant speed. ## Thermal envelope, cooling and panel fit Ambient humidity below 90% RH (non-condensing) and storage/transit temperature -20 °C to 60 °C define the cabinet environment — a standard industrial enclosure meets both, but a washdown or outdoor cabinet with condensation risk needs space heating or a conformal-coated variant outside this rating.","metaTitle":"Delta VFD450B43A AC Drive, 60 HP, 460V 3-phase","metaDescription":"Delta VFD450B43A B-series variable frequency drive, 460V three-phase, 60 HP (45 kW), fan cooled, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"43":"460V Three phase","450":"60 HP(45kW)","A":"Version Type","B":"B series","VFD":"Variable Frequency Drive","title":"VFD450B43A","Weight":"36 Kg","Product No.":"VFD450B43A","description":"AC Drives","Product Type":"AC Drive Motors","Voltage Class":"460V","Cooling Method":"Fan Cooled","Skip Frequency":"Three zones, settings range 0.1-400Hz","Shipping Weight":"38 Kg","lifecycle_stage":"current","Ambient Humidity":"Below 90% RH (non-condensing)","Overload Endurance":"150% of rated current for 1 minute","Estimated Lead Time":"Usually ships in 1-10 working days.","Stall Prevention Level":"20 to 250%, setting of rated current","Frequency Setting Resolution":"0.01Hz","Storage/ Transportation Temperature":"-20 C to 60 C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,476.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/291df42255924d9877f5c5fc750a3a51.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second source for VFD450B43A?","answer":"Within the Delta B-series 460V line, VFD370B43A (50 HP / 37 kW) is the closest functional sibling — same platform, same 36 Kg chassis, same 460V three-phase input. It is one frame down on power, not a different family, so the wiring and panel layout carry over."},{"question":"Will VFD450B43A drop into a panel that was originally specified around VFD370B43A?","answer":"Yes on the chassis and wiring — VFD450B43A and VFD370B43A share the same B-series 460V three-phase platform and the same 36 Kg frame, so the mounting footprint and termination pattern carry over. The motor lead sizing, breaker/feed sizing and any reactor selection must be re-checked for the 60 HP rating before commissioning."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/delta/VFD450B43A","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/delta/VFD450B43A when reusing this data.
