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
WATER PUMP WE HAVE SELECTING DOL AND WE USING FOR SAME H.P
MOTOR FOR MILL WE SELECTING STAR/DELTA.
