Allen-Bradley 160-BA03NSF1 Variable Speed Drive

The Allen-Bradley 160-BA03NSF1 is a 0.75 kW (1 HP) variable speed drive designed to regulate the speed of a three-phase AC induction motor on 380–460 VAC systems. It belongs to the 160 SSC Variable Speed Drives family and uses an analog signal follower architecture in an open IP20 enclosure for general‑purpose industrial installations. The drive supports a maximum output of 2.3 A and draws about 2.8 A of input current, with an operational input voltage range of 340–506 VAC and convection cooling for reliable operation. Weighing roughly 2.0 lb (0.91 kg), this compact unit provides speed control for 3-phase induction motors in industrial environments. As a legacy Rockwell Automation part, the 160-BA03NSF1 is considered discontinued/obsolete by many distributors, so current availability is typically limited to surplus or refurbished units.
