Medium voltage breakers how to choose
Circuit breakers for power distribution. Distribution circuit breaker is generally used in the low-voltage power grid circuit breaker dedicated to the distribution of electrical energy, including the power supply circuit breaker and load branch circuit breaker. In the selection of this type of circuit breaker, special attention should be paid to the following selection principles: line allowable current-carrying capacity is not less than the circuit breaker's long-delay action current setting value. If the use of wire and cable, the circuit breaker long delay action current setting value can be taken as 80% of the allowable load current of the wire and cable.
Motor protection type circuit breaker selection. To determine the rated current of the motor circuit breaker long delay action current setting value. Circuit breaker 6 times the long delay action current setting value of the return time > motor of the actual starting time. Circuit breaker instantaneous action current setting value: cage motor should be 8 to 15 times the rated current of the disconnectors; wire-wound motor should be 3 to 6 times the rated current of the disconnectors.
