What is the difference between an air circuit breaker and a leakage protector?

The decoration involves circuit installation, and electricity must be safe. For example, the choice of switch, first of all, to ensure safety. In circuit switches, the commonly used switch types are air switches and leakage switches. What is the difference between an air circuit breaker and a leakage protector, and which one is safer, an air circuit breaker or a leakage protector, let an electrician tell you.

1. Different protective effects
Generally speaking, the air circuit breaker is suitable for preventing the circuit from being overloaded and preventing the human body from being electrocuted, so it acts as a fuse.
The leakage protector is also to prevent the human body from electric shock and leakage, but this kind of circuit will not play a big role when it is overloaded. For some small circuits, it can play a protective role.

2. Different methods of motion detection
When the circuit is overloaded and tripped, it can be used to protect the safety of electricity consumption.
The leakage protector can detect the remaining current, the purpose is to protect the loop current, avoid the leakage value, cut off the leakage protector, and prevent the click of the leakage current.

3. Different reasons for tripping
The air switch mainly passes through the live wire and the neutral wire. If the current between the two wires is relatively large, it will trip.
The main reason for the leakage protector is the live wire. When it is in contact with the live wire and the ground, there will be a loop, and the device inside will automatically sense so that it can achieve the purpose of tripping and play a protective role.

Can the leakage switch and air switch be installed at the same time?
Can be installed at the same time - not only can but must be installed at the same time. The air switch and the leakage switch are complementary and cooperate with each other. They can make up for each other's shortcomings when they are used together. The air switch lacks an important protection function - leakage protection. This point can just be compensated by the leakage switch - the only difference in function between the leakage switch and the air switch is that the leakage switch has a leakage protection function. Therefore, leakage switches must be used in circuits prone to leakage.

Overview of Air Circuit Breakers
The air switch can also be called an air switch, or an air circuit breaker. It is a kind of circuit breaker. When the current in the circuit at home exceeds a certain amount, the air switch will trip, or there will be a short circuit in the circuit. In some cases, tripping will also occur, which has a certain protective effect on the circuit.
Overview of earth leakage protector
Leakage protection can also be called leakage protector, but only when the protected circuit is indirectly or directly connected to the earth, it will trip. And this leakage protector detects the residual current, which is the instantaneous value between the phase line and the neutral line current in the protection circuit.
Leakage protectors can be classified according to their protection functions, structural features, installation methods, operation methods, number of poles and lines, and action sensitivity. There are three kinds of protection switches and leakage protection sockets.

The air circuit breaker will trip when there is a short circuit in the protection circuit or the current is too high, while the leakage protection is to protect the instantaneous value of the current from being too large, which will cause harm to people. Although both protectors have a certain protective effect, it is necessary to choose a suitable protector in different environments.

Summary: What is the difference between the air switch and the leakage protector? The relevant content is introduced here. It can be said that there are still many differences between the two, such as different protection functions, different reasons for tripping, etc., so you must understand clearly when choosing to use them.
