STARTING CURRENT IS LOW.DOL STARTER NEED 1 CONTACTOR AND
1OLR, S/D NEED 3CONTACTORS,TIMER AND 1OLR FOR FULLY
AUTOMATIC.SEMI S/D NOT NEED FOR TIMER.
UPTO 5 H.P DOL STARTER USED.AND MORE THEN 5H.P USED S/D
STARTER.BUT DOL STARTER ALSO USED FOR ABOVE 15 H.P
ACCORDING TO THE LOAD.INCASE OF WE USING 10H.P MOTOR FOR
