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

The principle of the two is one of the differences between the air switch and the leakage switch, and the only difference is that the two are also different in terms of protection. The air switch is generally used for a long time to prevent the circuit from being overloaded, and in order to prevent the human body from being electrocuted, it only plays the role of a fuse; The leakage switch is to prevent electric shock and leakage of the human body, and it will not play a big role in the overload of the circuit. Because the working principle of the two is different, the resulting security protection is also different, so the two can not be blindly mixed.

The second difference between air switch and leakage switch is that the way of motion detection is different. The safety switch is purely tripping because the circuit is too heavy to protect the safety of electricity; The leakage switch detects the residual current, which is the algebraic sum of the neutral and internal phase of the protection loop current, so the device of this residual current only needs to avoid the leakage value, and is very sensitive to cut off the leakage switch to prevent the click of direct contact with the leakage current. So in terms of the way of motion detection, that's the biggest difference between the two.

There are many differences between air switches and leakage switches. For example, in terms of protection, the air switch only plays a protective role relative to the current of the large circuit, mainly detecting the short circuit in the circuit and carrying the excessive current, and the leakage switch is relative to the small circuit to protect the province, mainly detecting the line equipment, protecting the safety of the human body and the safety of the equipment; In terms of tripping, the safety switch is through the live wire and the neutral line, if the current between the two wires is too large, it will lead to tripping, and the leakage switch is only because of the live wire, the human body will contact the live wire and the ground to form a loop, which will cause the device inside to automatically touch, to achieve the purpose of tripping, playing a protective role.

The leakage protector has a large volumetric air switch. The leakage protector automatically trips when the electrical appliance leaks. The air switch automatically trips when the electrical current is too high. The above is the difference between a leakage protector and an air switch.

The difference is that one switch is not protected, and the other is protected, and the name already explains the difference.

The air switch is a bit better.

It has overload, short-circuit protection, and leakage protection function, which is the first choice for home decoration circuits.

The air switch is generally used for a long time to prevent the circuit from being overloaded, and in order to prevent the human body from being electrocuted, it only plays the role of a fuse; The leakage switch mainly protects the leakage of the circuit and prevents personnel from being electrocuted, and does not play a big role in the overload of the circuit. Therefore, the socket circuit in the home must use an air switch with leakage protection.

Because of the different working principles, the two functions cannot be replaced with each other. However, all of the above, air switches are a better choice than leakage switches.

There are some similarities in the appearance and function of leakage protection switch and air switch, so some consumers will confuse leakage protector and air switch, so what are the differences between leakage protector and air switch? Next, I will briefly introduce to you what is the difference between leakage protector and air switch.

1. According to Qeeka Home experts, there are differences in appearance and function between leakage protectors and air switches. For example, the leakage protector has a reset switch and a test switch, while the air switch does not. The leakage protection switch is mainly used to protect the safety of the human body, when the electrical appliances and lines leakage, the leakage protection switch will automatically short circuit to prevent electric shock accidents; The air switch mainly protects the circuit and electrical appliances, and will automatically cut off the circuit when the current is overloaded, which can prevent the electrical appliances and circuits from being burned.

2. We usually install leakage protectors and air openings when carrying out interior decoration, although there are some similarities between leakage protectors and air switches in appearance and function, but the two cannot be mixed. When you use the leakage protector, you should press the test button once a month to check whether the leakage protection function of the product is effective. If you press the test button and can't trip, then the leakage protector is abnormal and needs to be repaired and replaced.

3. Leakage protector and air switch are very important household appliances, and we try to choose local well-known brand products when buying air opening and leakage insurance. The more well-known brands in the market include Schneider, Legrand, Bull, Chint, Delixi Electric, Simon Electric and so on. In the case of ensuring product quality, we can compare several products, after-sales service, etc., and try to choose cost-effective products.

Summary: What is the difference between leakage protector and air switch, I will briefly introduce it to you here. I hope that after reading this article, you will be able to understand the difference between leakage and empty opening.

After having a certain understanding of air switches and leakage protectors, let's take a look at the difference between leakage protectors and air switches. First of all, the functions of air switches and leakage protectors are similar, they both have the effect of disconnecting the circuit, but the capacity of the air switch will be larger than that of leakage protection devices. Secondly, the appearance of the air switch and the leakage protection device is very similar, but the leakage protector has one more reset button and test button than the air switch.

In the circuit protection of households, leakage protection devices are often used, when the circuit of our household appliances is damaged is to prevent electric shock when a short circuit occurs, it is installed on the circuit of the user's distribution box, as well as the power line of the main distribution box on the floor of the community. The air switch will trip when there is a short circuit, so as to prevent electric shock and protect electrical appliances and personal safety.

Some friends will think that the functions of air switches and leakage protectors are similar, and they can be used interchangeably. This is not the case, although the leakage protector has one more protection function than the air switch, but we cannot replace the air switch with the leakage protector, because the trip function of the air switch is very important in industrial production, which is not solved by the leakage protector.

Air switches and leakage protectors are used in daily life, but they must be used before using them to achieve the effect. Let's introduce to you what is the difference between air switch and leakage protector. What is the difference between air switch and leakage protector 1. The protective function is different, and the air switch is generally suitable for preventing the circuit from being overloaded and preventing the human body from being electrocuted, so it plays the role of a fuse.

The leakage protector is also to prevent electric shock and leakage of the human body, but this circuit will not play a big role when it is too heavy, and it can play a protective role for some small circuits. 2. The way of action detection is different, when the circuit is too heavy and the guide trips, it can be used to protect the safety of electricity. The leakage protector can detect the remaining current, and the purpose is to protect the loop current, which can avoid the leakage value, cut off the leakage protector, and prevent the click that comes into contact with the leakage current.

3. The reason for tripping is different, and the air switch is mainly through the live wire and the neutral line, and if the current between the two wires is relatively large, it will trip. The main reason for the leakage protector is the fire wire, and when it comes into contact with the fire wire and the ground, there will be a family shelter and shout a loop, and the device inside will be automatically touched by Zhaoye, so as to achieve the purpose of tripping and play a protective role. What is an air switchAir switch compared with traditional switches, it can be said to be a kind of control equipment, which can play a protective role in the use of the circuit, and when the electrical equipment is under load, it is more suitable for use in the starting motor.

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 effects, different tripping reasons, etc., so you must understand the use clearly when choosing.

1. The protective effect is different, the air switch is generally used for a long time to prevent the circuit from carrying too heavy, in order to prevent the human body from being electrocuted, it only plays the role of a fuse, and the air switch only plays a protective role relative to the current of the large circuit, mainly detecting the short circuit in the circuit and carrying the excessive current. The leakage protector is to prevent electric shock and leakage of the human body, and it will not play a big role in the overload of the circuit. The leakage protector is relative to the small circuit production and provincial protection function, mainly to detect the line equipment, protect the safety of the human body and the safety of the equipment.

2. The way of action detection is different, and the safety switch is purely tripping because the circuit is too heavy to protect the safety of electricity. The residual current detected by the leakage protector is the algebraic sum of the neutral and inner phase of the protection loop current, so the residual current device only needs to avoid the leakage value, and it is very sensitive to cut off the leakage protector to prevent the click of direct contact with the leakage current.

3. The reasons for tripping are different, the safety switch is through the live wire and the neutral wire, and if the current between the two wires is too large, it will cause tripping. The leakage protector is because of the live wire, and the human body will form a loop with the ground when it touches the live wire, which will cause the device inside to automatically touch it, achieve the purpose of tripping, and play a protective role.

1. Different forms of control.

2. The principle of power failure is different.

The air switch is disconnected by judging whether the loop current is overloaded; The leakage protector is when the human body touches the fire line, the human body and the fire line form a state of "people", "fire" and "ground".

3. Different levels of protection.

The air switch is overcurrent protection, so it belongs to the safety level, while the leakage protector belongs to the milliampere level, because it is necessary to cut off the power supply in time to prevent someone from being electrocuted, so the level is higher than the air switch.

4. The objects of protection are different.

Air switch - to protect the equipment, the air switch is mainly to monitor the current of the line, if it exceeds its set value, it will jump open and include the cut-off circuit. Whether the high current is caused by excessive electrical power or a spinal shock or insulation damage, it will jump away.

For example, the air switch in the figure is set to 32A, and it will trip when this current is exceeded, while the circuit will not trip if it is less than this current. Generally, the air switch is also installed in the distribution box and is used as the main switch and each branch switch.

Leakage protector - to protect people, leakage circuit breaker has different specifications, now more use two-in-one type (RCBO, leakage plus short circuit overload protection in one), when it is used when leakage is detected, it will be broken. For example, if the water heater leakage is detected by the [leakage protector], the power supply will be cut off to prevent people from being harmed.

Leakage protectors are larger in size than air switches, and are also more expensive than air switches. There is also a test button on the leakage protector, which is recommended to be pressed every month to test whether the leakage trip function is intact.
