when i am going to take trail on a 3ph sq.i/m motor 5.5kw,
i observed that RPM of the motor is very low as compared to
the rated RPM and also it rotates in clockwise in first ON
command,and anticlock wise in second ON command.
finally i observed that on phase is no available .
but iam not clear about, why the motor is rotates in both
directions without any phase interchanging.pls answer to my
question.

The direction is changed by interchanging 2 phases and third
phase is taken directly.

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
