ANSWER:Nothing will happen.But fuse will blown off.
EXPLANATION: While applying DC voltage to the
transformer,there is no induced EMF in the primary &
secondary wdg.(except during switching period, both ON&
OFF).so,the transformer will draw high current from the
supply which detoriate the winding insulation & cause
transformer to burn.But actually this will not
happen .Becoz,the fuse will sacrifice itself to protect
transformer from high current.

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?
