How is the making capacity of the circuit breaker calculated?
1
Making capacity = 2 × \(\sqrt {1.8}\) × Symmetrical breaking capacity
2
Making capacity = 1.8 × \(\sqrt 2\) × Symmetrical breaking capacity
3
Making capacity = 3 × \(\sqrt {1.8}\) × Symmetrical breaking capacity
4
Making capacity = 1.8 × \(\sqrt 3\) × Symmetrical breaking capacity
