Overview
The Delta VFD075B43A is a 10 HP (7.5 kW) variable frequency drive with 460V three-phase input, part of Delta's VFD-B series for general-purpose AC motor control. Its 150% overload rating for one minute provides the headroom needed for motor inrush and short-duration peak loads — a practical margin that reduces nuisance tripping on conveyors, pumps, fans, and machine tool spindles.
This is a legacy VFD-B series model. Delta has transitioned the product line to the C2000 series, and multiple distributors now list the VFD075B43A as discontinued. For new installations, the direct successor is the VFD075C43A. We carry the VFD075B43A primarily for maintenance teams and retrofit jobs — swapping in the same model avoids re-terminating panels, re-tuning parameters, and re-validating PLC communication.

Practical Notes
Replacement Strategy. If you are keeping an existing B-series installation running, a direct VFD075B43A swap is the lowest-risk path — same footprint, same terminal layout, same parameter set, zero recommissioning. If the downtime window allows and you want to modernize, the VFD075C43A (C2000 series) brings sensorless vector control and a higher-resolution control platform while retaining a similar form factor. We can quote both so you can weigh lead time against upgrade benefit.
Typical Applications. A 10 HP 460V-class drive in this category typically powers medium-duty industrial loads: centrifugal pumps, cooling tower fans, air compressors, mixers, and extruders. For constant-torque applications running below 30 Hz, verify that the motor has adequate cooling (separately driven fan or oversized frame) — this is standard practice across all VFD installations, not specific to this model.
Installation Guidance. As with any VFD of this power class, plan for adequate enclosure ventilation, keep motor cable runs as short as practical, and use VFD-rated cable to contain common-mode noise. These are standard practices that apply universally — but they are the difference between a drive that runs for a decade and one that nuisance-trips every season.
Sourcing & Availability
We currently hold 22 units of the VFD075B43A in our Shenzhen warehouse, ready for same-day dispatch to Asia-Pacific destinations. Reference pricing is approximately $916 per unit; final price is confirmed on RFQ based on quantity, shipping terms, and urgency.
Our supply chain is anchored in Shenzhen's Huaqiangbei industrial electronics hub — the world's densest marketplace for automation components. This gives us access to factory-packaged inventory at pricing that competes with surplus channels but with distributor-grade traceability. Every VFD we ship is factory-sealed in original packaging.
