ABSTRACT:
A motor control technique is disclosed in which a first algorithm controls interruption of power to a motor in a first current range. A second algorithm controls interruption of power in a second, higher current range. The algorithms may be adapted to specific motor sizes, ratings or classes. The extended range may extend from a transition point (e.g., 6–10 times the FLC of the motor) to an upper limit. The upper limit may be determined based upon a current rating of an instantaneous trip device.
