is used more and more widely nowadays. it can protect circuit in daily life. when the circuit is short-circuited or overloaded, it will automatically cut off the current, which greatly reduces the risk of electrical fire in life. in the choice of circuit breakers, many people do not know how to choose the right circuit breaker. here is how to choose the right circuit breaker for you. application of

circuit breaker:

1. firstly, according to the specific conditions of use, the specific parameters are determined according to the rated current of the circuit and the requirements of protection. when the rated current is below 630 a, the short circuit current is not too large. plastic case circuit breaker is preferred. the rated current is relatively large, the frame circuit breaker is better, and the plastic case circuit breaker with good performance is better. it should be noted that for branches with large short circuit current, it is necessary to calculate whether the current limiting capacity of circuit breakers can meet the requirements. circuit breaker should have this function when there is leakage protection requirement. when

decides which kind of circuit breaker to choose, what needs to be compared is the performance-price ratio of the circuit breaker {span 0} under the condition of satisfying the basic use, it depends on whether the circuit breaker is safe and reliable, whether it has a certain degree of extensibility, such as adjusting to adapt to the change of load in a certain range, adding module units to achieve functional expansion, etc. . how to protect the circuit when using

circuit breaker: in the process of using plastic case circuit breaker, once the circuit breaker short circuit or overload occurs, the tripper of the circuit breaker will suck with the armature and make the outlet mechanism operate, which will disconnect the main circuit. when the circuit is overloaded, the thermal element will bend and the main circuit will be disconnected. when the circuit is short of voltage, the undervoltage tripper will release.

's current distribution system not only requires circuit breakers to turn off current to achieve circuit control, short circuit and overload protection skew, but also provides security protection system. personal safety, equipment safety and reliability of power distribution system have all raised new requirements. therefore, the choice of products should also consider personal safety.

in the protection of electrical circuit and equipment, power supply and other aspects
