Summary： As the name suggests, it is designed to prevent electrical leakage
As the name suggests, it is designed to prevent electrical leakage, also known as a leakage protection switch. It is a combination of a leakage protection plug and an air switch to prevent the harm of electrical leakage to the human body caused by machinery and equipment. Normally. There are several connectors at the bottom of the leakage protection plug, each connected to a different motor. When the voltage exceeds the normal 220 volts, one of the connected motors will jump, sound an alarm, and disconnect the circuit in a short period of time. The power-off protection action is usually within 1 second. And the role of prayer protection. Of course, the sensitivity of different types of protectors also varies.
Air switch is a general term for a switch in the circuit of a switching device, which can be divided into many types. But its important function is to provide protection against overload and short circuit. He has an effect on the live and neutral wires, similar to the function of common fuses. The leakage protection plug only works when the human body comes into contact with the live wire.
The difference between a leakage protection plug and an air switch is that an air switch is mainly suitable for lighting and short circuiting in power distribution. It is an air isolation switch and does not have a persistent function, while a leakage protection plug is more widely used and works by detecting the presence or absence of leakage.
Actually, whether to use a leakage protection plug or an air switch depends on your usage requirements and scope. It depends on the situation.
