How to choose medium voltage circuit breakers

Selection of circuit breakers for power distribution. Distribution circuit breakers are generally circuit breakers used in low-voltage power grids specifically for distributing electric energy, including main power supply circuit breakers and load branch circuit breakers. When selecting this type of circuit breaker, special attention should be paid to the following selection principles: the allowable current carrying capacity of the line is not less than the long-delay operating current setting value of the circuit breaker. If wires and cables are used, the long-delay operating current setting value of the circuit breaker can be 80% of the allowable current carrying capacity of the wires and cables.

Selection of motor protective circuit breakers. The long-delay operating current setting value of the circuit breaker is determined by the rated current of the motor. The return time gt of the 6 times long delay action current setting value of the circuit breaker; the actual starting time of the motor. The instantaneous operating current setting value of the circuit breaker: the cage motor should be 8 to 15 times the rated current of the release; the winding motor should be 3 to 6 times the rated current of the release.
