The initial connection should be in the star pattern that results in a reduction of the line voltage by a factor of 1/√3 (57.7%) to the motor and the current is reduced. A dual starter connects the motor terminals directly to the power supply.hence, the motor is subjected to the full voltage of the power supply.consequently, high starting current flows through the motor. The control circuit uses to control the starter circuit such as on, off and tripping operations.
