A motor starter. The motor starter comprises a motor; start, run, shorting and transition contactors operably associated with the motor; and run, start, shorting and transition auxillary contactors. The transition auxillary contactor operably controls the operation of a shorting contactor, and the shorting auxillary operatively controls the operation of the run contactor.
