Product Description
The Allen-Bradley/Rockwell Automation 150-A68NA smart motor controller, part of the Bulletin 150 SMC-2 series, is designed for electromechanical motor starters and offers easy, digital setup without analog potentiometers. This open-enclosure controller, rated at 68 Amps and 20-60 HP at 575 VAC, operates at 50-60 Hz with a 200-230 VAC three-phase input. It features a built-in energy saver, optional protective module mounting, and is CE marked, UL listed, and CSA approved. SMC-2 controllers, available in 5-97 Amp variants for 200-575V ranges, can be configured as series or motor controllers with an interface option for direct on/off control, auxiliary contact selection, and soft stop. Controllers with interface options can operate without electromechanical motor starters. Its operating temperature range is 0-50C, and storage is -20-75C.
Is Your Device Showing These Signs?
The Allen Bradley 150-A68NA commonly experiences issues related to contact wear, coil failure, and overload relay tripping. Technicians address contact erosion through refurbishment or replacement to ensure proper motor control. Coil burnout is resolved by replacing the coil, verifying correct voltage, and inspecting for wiring faults. Overload relay trips are investigated by checking for excessive motor current draw, phase imbalance, or incorrect overload settings, often requiring adjustment or replacement of the overload block. Routine inspection and preventative maintenance are essential to mitigate these issues and maintain optimal performance of the 150-A68NA motor controller.
