Nader Circuit Breaker

Short-circuit breaker breaking capacity ≥ lines prospective short circuit current. Suppose a power supply (SL7 10 / 0.4kV transformer) capacity of 1600kVA, the secondary current of 2312A, short-circuit current which is at the outlet end of 5m 42.96kA. Is a rated current branch 125A, since this leg ...

How to choose the circuit breaker (low voltage) correctly? (1) The rated current of the circuit breaker is determined by the calculated current of the line; (2) Check the breaking capacity of the low-voltage circuit breaker according to the maximum short-circuit current of the line; (3) Check the sen...
