Circuit breaker design of explosion-proof distribution box

 There are many factors that determine the quality of explosion-proof distribution box, among which the quality is determined by the circuit breaker. This is because the circuit breaker is the main component of the explosion-proof distribution box, so when we choose the explosion-proof distribution box, we need to pay attention to this aspect.

In the design of explosion-proof distribution box, the manufacturer will place the circuit breaker at the position of the main switch, so as to ensure the safety of the whole line. Of course, in each branch circuit, the circuit breaker can also be designed, but this way of design is obviously more resource-consuming, so such a design is not recommended.

When use, if the main switch occurs leakage, the circuit breaker short trip value, it can make the phenomenon of leakage occurred without tripping circuit. So, when this kind of design method is not correct, so we will be in the trunk road design circuit breaker, in branch circuit design, circuit breaker, it is mainly used in places where circuit is more used, if the line is not much, to the section design of circuit breaker.
