why we use the fuse in only one wire? althrough in ac
current the current flows in both directions.
why the neutral wire can be taken half the magnitude of
phase wire while same current returns from neutral wire?
Answer Posted / umesh 123
Firstly the current flows through the phase wire and returns in neutral.if we connect the fuse in neutral it will burn after sh ckt, but the line lives in load(machine) so it will harmful
2nd- the magnitude of neutral cable is half 3 phase line where the unbalanced load(current) returns through neutral.

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?
