No dear in star delta we mounting OLR in phase current(mounting OLR exectly below to the main contactor),we can also put OLR in line current but we cant do that bcoz the main reason of money saving.If we put OLR in with line current (or say above the main contactor )we require relay range similar to the FLC so its higher rating and its cost is more than halved rating.Its a main reason to put OLR in phase current. For your refrence please find the attach sheet of star-delta wiring drg and control too.
