Which of the following statement is true about the Making Capacity of Circuit Breaker?
1
It is current (RMS) that a circuit breaker is capable of breaking at given recovery voltage and under specified conditions
2
It is the peak value of current (including DC component) during the first cycle of current wave after the closure of circuit breaker
3
It is the period for which the circuit breaker is able to carry fault current while remaining closed.
4
Making capacity = √3 × Symmetrical breaking capacity
5
None of these
