I could be wrong but wouldn't the FLA formula actually be FLA= (KVA x 1000)/(sqrt(3) x V)

Full load amps do not identify the transient (short time) and sub transient (instantaneous) fault current.

Hi, how would you calculate the tripping current of the circuit breaker if it set to 125%? Thank you in advance.

You have to look at the time to current curves for the specific breaker. You should be able to obtain these from the circuit breaker manufacturer.

How would you calculate the DC component?
