Circuit breaker high voltage circuit breakers, and low voltage circuit breakers are an electrical protection device, and there are many types of arc extinguishing devices. The full name of the air switch is that the air type low voltage circuit breaker belongs to the circuit breaker and is mainly used in the low voltage circuit. The isolating switch is a high-voltage switchgear mainly used in high-voltage circuits. It is a kind of switchgear without arc extinguishing device. It is mainly used to disconnect the circuit without load current, isolate the power supply, and has obvious disconnection in the open state. Point to ensure the safe maintenance of other electrical equipment. In the closed state, the normal load current and the short-circuit fault current can be reliably passed. Because it does not have a special arc extinguishing device, it cannot cut off the load current and short circuit current. Therefore, the isolating switch can only be operated when the circuit has been disconnected by the circuit breaker. It is strictly forbidden to operate with load to avoid serious equipment and personal accidents. Only the voltage transformer, the lightning arrester, the no-load transformer with the excitation current not exceeding 2A, and the no-load line with the current not exceeding 5A can be directly operated by the isolating switch.

Because it uses the air as a medium to extinguish the arc, it is called the air type low-voltage circuit breaker. It is called the air switch. The power distribution in our usual building is basically air switch.
In power applications, most of them are connected by circuit breakers and isolating switches. The circuit breakers are used to cast and cut the load (fault) current, and the isolation switch is used to form a clear disconnection point.
