Air switch selection method one
In the selection of air switches, you should choose from the direction of large to small. Air switch if home, then just consider whether it can carry the current of the home, including the total rated current of the living room, bedroom, kitchen, bathroom, if not home, it is more necessary to choose from the direction of large to small, so as to ensure that the air switch can withstand a larger current, and will not occur in the case of short-circuiting of the current and so on. So the first method of selecting the air switch introduced is to choose from the direction of large to small.
Air switch selection method two
In the purchase of air switches before, be sure to first figure out your home switch as well as the circuit switch, the so-called home switch refers to the unit downstairs of the main meter to the home line, look at the total rated current, in the look at the home of the maximum load current, to determine the value of a minimum rated current, and the circuit switch refers to the circuit of the home must be from the positive pole to return to the negative pole, to form a minimum rated current value, and the circuit switch refers to the circuit of the home must be from the positive pole Departure in the return to the negative pole, the formation of a circuit process, simply put is a circuit to turn on the power supply. These two aspects are also to be used as a selection aspect of the air switch to reference.
Air switch selection method three
After knowing the current of their own home, the next step is to choose the model of the air switch, according to my understanding of the situation, the model of the air switch has the following kinds of air switch, DZ47, DZ10, DZ5, DZ15, as well as DZ20 several air switch models of which the DZ5 is the smallest, applicable to the rated current 50A circuit, DZ47 is suitable for rated current 50A circuit, DZ47 is suitable for rated current 50A circuit, DZ15 is suitable for rated current 50A circuit. circuit, DZ47 for 60A current, and 240v/415v below the working voltage, the largest model of air switch for building circuits, the largest should belong to the four air switches, its rated current reaches 630A, 400v below the working voltage, can completely guarantee the safety of the circuit, but for home use, generally do not need to use such a large size of the Air switch. So the choice of air switch, in terms of model, also need to match.
Air switch selection method four
The role of the air switch is to protect the safety of electricity, in the process of excessive current, once the bearer can not afford, the air switch should be automatically off, to achieve the purpose of tripping, so in the selection of air switches, off whether according to the bearer of excessive current to achieve the purpose of tripping, this is also the selection of air switches of a knowledge point, the air switch. Simply put, the existence of the air switch release is to trip, but also a low-voltage switching device, then in the course of different currents, the time of release will be different. For example, when the rated current is twice as much, it should be automatically decoupled after more than two seconds.
Air switch selection method five
The previous section tells a lot about the air switch selection method, if you still don't quite understand how to choose the air switch, you may want to go to a professional to carry out the installation, so that you won't be troubled by the choice of air switch. Finally, I tell you here, I hope you can know more about the air switch and familiar with its working principle, protect the air switch, and safe electricity. Let your family enjoy a more comfortable and safer and more secure living space.

The details of the air switch, I have finished giving you an introduction. I believe that we have a lot of places in our daily life with the switch, so when you buy, I recommend that you go to buy the air switch, because its safety performance is much higher than the ordinary switch. I believe that with the continuous development of science and technology, the future of power products will tend to be intelligent. That will be more convenient for our lives, thus improving our quality of life.
