Allen-Bradley 150-A97NB Smart Motor Controller

Allen-Bradley 150-A97NB SMC-2 Smart Motor Controller is a 97 A, 55 kW open-type soft-start controller designed for 3-phase induction motors on 400–480 VAC, part of the SMC-2 family. It operates as an open-type controller (Series A) and uses the 150-NA interface module with programmable software to tailor ramp rates, current limiting, and motor-protection features. This standalone device is built for industrial applications that require controlled motor starting and protection without a traditional full drive, and can be integrated into Allen-Bradley control schemes for compact motor management. The 97 A rating corresponds to motors in the roughly 60–75 HP range at 480 VAC, offering a compact solution when soft-start capability is preferred over direct-on-line starting.
