How to Calculate Circuit Breaker Tripping Settings
Calculation of instant short circuit tripping of circuit breaker is based on following inputs in this Excel File :
Voltage(L-L)
Voltage(L-N)
Instantaneous Short-Circuit Tripping Set
Accuracy
Cable Size
Cable Material
Actual Length of Cable
And according to what you select or choose, result of maximum length of cable for your tripping setting is calculated. Selection of fuse is based on circuit wire size input (1,5mm2 – 70mm2).
