On a 10 KVA UPS we have to provide a DC MCB for Battery bank
of 16 nos (12 V 65 AH).
What Shall be the current rating of DC MCB ?

Answer Posted / ravi v nair

Battery banks are always connected in series so the total
voltage of the battery bank will be
12*16=192V
10KVA=10000VA
A=10000/192=52.08
we need a 55A DC MCB
