Hello everyone, Lin Fei to answer the above questions, empty selection specification requirements, empty choice many people do not know, now let's take a look at it!

1. The switch is an indispensable tool in our life. If there is no switch, it will consume electricity unnecessarily, which virtually increases our daily electricity consumption. Therefore, the role of the switch can not be ignored. And the types of switches are also different, and the air switch is one of them. Maybe many of them don't know much about air switches. Let's take a look at the selection and purchase skills of air switches.

2. In the choice of air switch, choose from large to small. If the air switch is used for household use, you only need to consider whether it can carry the current in the home, including the total constant current in the living room, bedroom, kitchen and bathroom. If it is not for household use, it is more necessary to choose the direction from large to small to ensure that the air switch can withstand a larger current without short circuit. Therefore, the selection method of the first air switch introduced by Bian Shaw is from large to small.

3. Before buying an air switch, be sure to know your home switch and circuit switch. The so-called door switch refers to the line from the master meter downstairs to the home. Check the total fixed current and maximum load current at home to determine the minimum rated current. The loop switch refers to the household circuit, which must start from the positive pole and return to the negative pole to form a loop. Simply put, it is a circuit connected to a power supply. These two aspects should also be used as a reference for selecting air switches.

4. After knowing the current in your home, the next step is to choose the model of the air switch. According to Bian Xiao's understanding, there are the following types of air switches: DZ47, DZ10, DZ5, DZ15, DZ20, of which DZ5 is the smallest, suitable for circuits with rated current of 50A, DZ47 is suitable for current of 60A and working voltage below 240v/415v. The largest type of air switch is suitable for building circuits, and the largest one should belong to IV type air switch. Its rated current is less than 630A and 400V, which can ensure the safety of the circuit. However, it is usually unnecessary for families to use such large air switches. Therefore, the choice of air switch, in terms of model, also needs to be matched.

5. The function of air switch is to protect the safety of electricity. In the process of excessive current, once the load cannot be carried, the air switch should trip automatically to achieve the purpose of tripping. Therefore, in the selection of air switch, whether the release can achieve the purpose of tripping according to the load current is also a knowledge point in the selection of air switch. To put it simply, air switch tripping exists for tripping, and it is also a kind of low-voltage switching device. Then in different current processes, such as when the rated current is twice as high, it will be blurted out automatically for more than two seconds.

6. Earlier, Bian Xiao talked a lot about the selection of air switches. If you still don't know how to choose an air switch, ask a professional to install it. In this way, you will not be bothered by the choice of air switch, and it is also a good way. Finally, I hope you will know more about the air switch, be familiar with its working principle, protect the air switch and use electricity safely. Let the family enjoy a more comfortable, safer and more secure living space.

7. It is very difficult for people to buy air switches, because many consumers know nothing about air switches, so we need to be familiar with some little knowledge of buying air switches. The above is easy to understand the common sense of choosing and buying air switches. If consumers want to buy air switches, they can refer to the purchase method.

At the end of this article, I hope it will be helpful to you.
