Rated Current Of Low Voltage Pole Mounted Circuit Breaker

1.Lv Pole Mounted Circuit Breakers Protection (transformer secondary side)
A: Overload protection
Overload protection setting current: Idz=Kk Ieb
Where: Idz—setting current of the circuit breaker long-time delay release (A)
Ieb—rated current of the transformer low-voltage side (A)
Kk—reliability coefficient, considering the setting error, generally 1.1.
