Miniature circuit breakers are the most common. The hotels you live in and the shopping malls you visit all have their own features. You can find the corner of your house. Every house may be in different locations, but it is no exaggeration to say that almost every house can be found.
So what's the function of circuit breaker? Simply speaking, it is to protect our electricity safety and prevent electric shock accidents. Circuit breaker can work without fault and under certain fault conditions to protect power lines.
The protection function of circuit breaker mainly refers to the working condition under the fault condition. The fault condition mentioned here refers specifically to the overload or short circuit of the circuit. When the overload or short circuit occurs in the circuit, the circuit breaker is the equipment used to cut off the current.
The protection function of circuit breaker is mainly realized by using: the current in the circuit is larger than that in normal fault-free operation when overload and circuit break occur. It is very important to know this, which is the basis of the realization of circuit breaker protection function.
