Allen-Bradley 1305-BA03A-ES-HA2 Variable Frequency Drive

Allen-Bradley 1305-BA03A-ES-HA2 is a 380–460 V, three-phase variable frequency drive (VFD) designed to control small- to mid-size AC motors. It delivers 1 HP (0.75 kW) of output with a continuous current rating of 2.3 A, making it suitable for 3‑phase motors in the 0.75 kW range at that voltage. The drive accepts 3‑phase power in the 380–460 V range and provides speed and torque control for precise motor regulation in industrial systems. Typical applications include conveyors, pumps, and fans, where smooth acceleration and variable speed improve process control and energy efficiency. The model is identified by the part number 1305-BA03A-ES-HA2 and belongs to Allen-Bradley’s legacy 1305 Adjustable Frequency Drive family, a line historically used in retrofit projects and legacy equipment requiring a compact 3‑phase VFD for 380–460 V service. Installations should follow the manufacturer’s wiring and safety guidelines and comply with local electrical codes.
