The Allen-Bradley 150-A68NB-NA controller, part of the SMC-2 series, is a high-performance motor controller designed for three-phase squirrel-cage induction motors. With current ratings from 5 to 97 Amps and voltage ranges of 200 to 230 Volts, 380 to 460 Volts, and 500 to 575 Volts, this controller supports soft start, current limit start, and full voltage start modes. Rated at 68 Amps, it handles an output of 20 to 60 horsepower at 575 Volts AC or 18.5 to 45 kilowatts, offering an energy-saving feature for motors under partial or no load. The device's robust design, compliant with CSA industrial standards, includes open, NEMA Type 4 (IP 65), and NEMA Type 12 enclosure options, and it operates efficiently within a standard line frequency of 50 to 60 Hertz. Additionally, the controller accommodates control voltages of 200 to 240 Volts or 100 to 120 Volts in single-phase setups.
