Ambient humidity is rated below 90 % RH non-condensing and storage/transport temperature spans -20 C to 60 C, which defines the climate envelope between uncrate and commissioning. ## Ratings that decide the fit The 150 % of rated current for 1 minute overload endurance is the duty figure that actually governs sizing for high-inertia loads — fans and conveyors ride below it, but mixers and crushers regularly push past 100 % during start-up, and the one-minute ceiling is what separates a real fit from a nuisance-trip. Stall prevention is adjustable from 20 % to 250 % of rated current, giving the integrator room to tune the protection level to the mechanical load rather than living with a fixed factory default. Frequency resolution is 0.01 Hz and three skip-frequency zones cover 0.1–400 Hz, which is the parameter set a commissioning engineer reaches for first when the motor exhibits a resonant whine at a specific operating speed. ## Sourcing and lifecycle posture Estimated lead time on the listing is one to ten working days, a typical industrial-automation distribution window for an active drive in this frame size rather than a same-day ship — the exact slot depends on the RFQ quantity and the warehouse holding it at quote time.","metaTitle":"Delta VFD370B43A AC Drive 50 HP 460V 3-Phase","metaDescription":"Delta VFD370B43A 460V three-phase variable frequency drive rated 50 HP (37 kW), fan-cooled.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"43":"460V Three phase","370":"50 HP(37kW)","A":"Version Type","B":"B series","VFD":"Variable Frequency Drive","title":"VFD370B43A","Weight":"36 Kg","Product No.":"VFD370B43A","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":"$3,144.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/291df42255924d9877f5c5fc750a3a51.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy VFD370B43A and how do I get a price?","answer":"Pricing, current availability, and the exact lead-time window are confirmed when an RFQ is submitted — the storefront does not carry a published unit price or a fixed ship date on the listing."},{"question":"What does the 50 HP (37 kW) rating actually mean for motor sizing on VFD370B43A?","answer":"It defines the continuous motor output the drive can deliver on 460 V three-phase; the additional 150 % rated-current overload for 1 minute is the duty figure that governs high-inertia start-up on mixers, conveyors, and crushers rather than the headline horsepower alone."},{"question":"Can VFD370B43A replace a VFD300B43A in an existing panel without rewiring?","answer":"Both are 460 V three-phase B-series drives with the same 36 Kg drive weight and 38 Kg shipping mass, so the cabinet footprint and field-terminal layout match; what changes is the motor-side current capacity, so the connected motor should be re-validated against the 50 HP rating rather than the 40 HP rating the original panel was sized for."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/delta/VFD370B43A","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/VFD370B43A when reusing this data.
