The Allen-Bradley 150-C201NBD is a sophisticated SMC-3 smart motor controller, engineered for advanced motor control and equipment protection using microprocessor technology. Suitable for 3-phase operations with a voltage range of 200-460V AC and a frequency range of 50-60 Hz, this controller efficiently manages output power across various modes, including Line and Delta modes, supporting motor capacities from 60 to 250 HP. With standard features like Soft Start, Current Limit Start, and adjustable overload protection, it includes built-in diagnostics, a rotary dial, and DIP switches for precise configurations. Its robust design, compliant with UL, CSA, and IEC standards, ensures reliable performance in demanding applications like compressors, pumps, and fans, with additional protections against over-temperature, phase imbalance, and SCR faults.
