Line to Line voltage or Phase to phase voltage is the
common way of representing the voltage. Also called as Line
voltage in Electrical System.

In case of 3 Phase system the Phase voltage (Line to
Neutral Voltage) is {{LINE VOLTAGE/ Root 3}} Therefore the
Single phase voltage is 400/1.732 That is near 230Volts.

why are we adopting 132kv,220kv for transmission rather than using 440kv at all transmission lines as it gives lower losses?

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?
