Development of miniature circuit breakers with selective protection Development of small circuit breakers with selective protection: low voltage circuit breakers are mainly used in power distribution networks, which can be used to distribute electrical energy and protect circuit and power equipment from over current (including overload and short circuit) and so on. The ideal mode of power supply is that once the current fault occurs in a certain place in the distribution network, the breaker of the circuit breaker is quickly removed. And not to cause harm to the low-voltage circuit breaker is mainly in the power distribution network, used to allocate power and protection circuit......
