Circuit breaker main circuit control power, how to wiring?
which should be not less than the effective value of the short-circuit current at which the contact begins to be separated) by the rated voltage. Of course, to single or three-phase. for reference only.
Otherwise you should use a larger capacity circuit breaker or technical transformation, reduce the installation of short-circuit capacity. Or on the circuit breaker capacity transformation
In use, the circuit breaker should be cut off the capacity of the installation should be greater than the maximum short circuit capacity
he blocking capacity is equal to the breaking current (the manual specifies the rated breaking current of the high voltage electrical appliance
