It looks very Hi guys. Electrical Safety Advice | ElectriciansForums.net. From your article I get that IEC 947-2 has stronger specs more than IEC 898-1 such as ( Ue , Ui , pollution degree) but how Icu for 947 ( stronger conditions ) can be greater than 898 for the same MCB, Dear Mostafa, in IEC 898-1 it is mainly used definition of Icn (rated (nominal) breaking capacity) but not Icu (ultimate breaking capacity) and it makes the difference. They also react faster than a circuit breaker, and they are believed to be more failsafe than breakers because they contain fewer moving parts. 1 is for AC, 2 is for DC.
