Circuit breaker generally choose what ah?
In the case of low voltage leakage protection grid installation, under normal circumstances, the grid line to ground leakage current (for three-phase power grid unbalanced leakage
Leakage protection is protected by a relative leakage or electric shock current that occurs within the detected grid and is fully protected as a trip signal and electrical trip task.
so RCD can cut very sensitive ground fault protection circuit can also be directly Use contact with backup shock protection.
To this end, set the value of RCD, that is, its current I △ n movement, just to escape the normal amount of leakage current value, the value of milliamperes,
