Abstract
Introduction was made to a low-voltage circuit breaker type selection method in distribution line, household use, similar sites load and motor loads. Analysis was made to type selection strategy under circuit breaker protection function and different load characteristics conditions. Reasonable type selection of low-voltage circuit breakers enables low-voltage circuit breakers to reach optimal protection status, so as to avoid safety dangers caused by unsuitable circuit breaker type selection and unreasonable installation.
