Product Description
The Allen-Bradley/Rockwell Automation 150-A68NB, an SMC-2 motor controller, utilizes microcomputer technology to control three-phase squirrel-cage induction motors ranging from 5 to 97 Amps. This UL, CE, and CSA certified solid-state controller, rated for 68 Amps and 20-60 HP at 575 VAC, operates between 0-50C and can be stored between -20-75C. It accepts a 380-460 VAC, 50-60 Hz input and functions in 0-95% non-condensing humidity. The 150-A68NB is an open-enclosure model without optional features, while other SMC-2 controllers offer configurations like soft stop, interface modules, and various enclosure ratings.
Is Your Device Showing These Signs?
The Allen Bradley 150-A68NB commonly experiences issues such as failed overload relays, requiring replacement to restore motor protection functionality.
