The B,C,D,K,Z indicates the instantaenous tripping current.
It means the minimum value of current causes the circuit to
trip without intentional time delay. approximately < 100ms.
Consider Rated Current be : (In)
Instantaenous tripping current for C Curve is 5-10 times
the rated current(In).
Instantaenous tripping current for D Curve is 10-20 times
the rated current(In).
