11KW Delta motor is taking about 44Amps in star and goes
upto 70Amps in delta and trips OFF. The rated current is
26Amps. Application is for the blower. The motor takes ( no
load without coupling impller ) only 2.5A and 5Amps in star
& delta starter test.Need to know why its taking high
current.

it alingment could be out. Because no load current of
motor is ok . So check the coupling alignment , motor
bearing and connection of input cable at main source.
