Application Note: Determining the Circuit Breaker Size

sections in standards such as IEC 60909, IEC 60364, UL 508A and NEC 2017. Some manufacturers provide detailed information about the transformershort circuit calculation procedure, and its effect on the selection of circuit breakers and fuses at the different hierarchical levels of the installation topology (see . Figure 1).
