what is difference between start imitation and start
interlock for 3 phase motor protection ?
Answer Posted / shivani
Start limitation means no. of start this is bercause if
consecutively u start the motor the motor got heated&
thermal conductivity will dec. .not goo for its health.
Start interlock means
frequency,voltage& powerrequirement we can control by
different relay so. after fullfilling those constraints
only it should start for giving poptimal performance.

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?
