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 / asif.k64@hotmail.com

UPS is 10 KVA, and battery is 65AH

Hence if it is a 1 phase UPS

KVA = V*A
10000 = 240*A
A= 10000/240
A = 42 A full load

Approximately a 63 A MCB would be required
