power distribution circuit breaker box

Principle of circuit breaker selection

1. Rated voltage of power distribution circuit breaker box circuit breaker ≥ rated voltage of line;

2, the circuit breaker rated current ≥ line calculation load current;

3. Rated current of power distribution circuit breaker box circuit breaker tripper ≥ line calculation load current;

4. The limit on-off capacity of the circuit breaker is greater than the maximum short-circuit current in the line;

5. The single-phase short-circuit current to ground at the end of the line shall be no less than 1.25 times of the automatic switching instantaneous (or short delay) tripping setting current;

Under-voltage tripper rated voltage of circuit breaker is equal to line rated voltage.
