3. Selection Principle

Distribution circuit breaker refers to the circuit breaker specially used to distribute electric energy in low-voltage power grid, including the main power switch and load branch switch. When selecting this type of circuit breaker, in addition to the above general selection principles, special consideration shall be given to limiting the system fault to the minimum range to prevent the extension of the power failure area in case of fault. Therefore, the following selection principles shall be added

1.The setting value of the long delay action current of the circuit breaker is ≤ the allowable current carrying capacity of the conductor. For the case of wires and cables, 80% of the allowable current carrying capacity of wires and cables can be taken.

2.The return time of 3 times of the setting value of the long delay action current is ≥ the starting time of the motor with the maximum starting current in the line.

3.Setting value of short delay action current ≥ 1.1 × (Ijx+1.35kIed)

Ljx – line calculation load current;

K-Multiple of starting current of motor;

Ied motor rated current.
