If you provide your email address, I can send to you the motor constants for delta or wye connection. Also, open GOOGLE.COM and enter "3 phase motor connections".

A: Hi...You will need 3 contactors and name them as Star, Delta and Main respectively. Even though all r same.

Give the line supply to a NC pushbtn switch and then connect one O/L relay in series with it. Now connect the other terminal of relay to the NO pushbtn switch.

Connect d other terminal of switch to d timer. Simultaneously, connect dis terminal of switch to NC terminal of Delta contactor and other end of NC contact of this contactor to Star contactor...

Buddy, It will be btr if u mntn ur E-id on d post...i will send u a complete ppt of star delta that i made.
Cheers...
