A three phase load, around 4 km away from the 11/0.433KV
distribution transformer (Neutral of Transformer is
solidily earthed) and consisting of mainly very costly and
sensitive electronic equipments is giving trouble due to
high voltage difference between neutral and body earth.
Whether this problem can addressed by connecting neutral at
the load point solidly to earth?

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?
