Air switch, also called air circuit breaker, is a type of circuit breaker. It is a switch that will automatically open whenever the current in the circuit exceeds the rated current. The air switch is a very important electrical appliance in the low-voltage distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing contact and breaking circuits, air switches can also protect short circuits, severe overloads and undervoltages in circuits or electrical equipment.

1. Follow the direction from large to small.
If the air switch is for home use, then you only need to consider whether it can carry the current in the home, including the total rated current of the living room, bedroom, kitchen, and bathroom. If it is not for home use, you need to choose from large to small, so as to ensure The air switch can withstand larger currents and will not cause current short circuits.
2. Before purchasing an air switch, you must first understand your entry switch and loop switch. The so-called entry switch refers to the line from the main meter downstairs in the unit to the home. Look at the total rated current, and then look at the maximum load current in the home to determine a minimum rated current value. The loop switch refers to the circuit of the home decoration, which must be The process of starting from the positive pole and returning to the negative pole to form a loop is simply a circuit that turns on the power. These two aspects should also be used as a reference for the selection of air switches.
3. After knowing the current of your home, the next step is to choose the model of the air switch. According to the editor's understanding, there are several air switch models: DZ47, DZ10, DZ5, DZ15 and DZ20. Among them, DZ5 is the smallest, suitable for circuits with a rated current of 50A, and DZ47 is suitable for 60A. current, and working voltage below 240v/415v. This largest model of air switch is suitable for building circuits. The largest one should be a four-level air switch. Its rated current reaches 630A and the working voltage below 400v can fully guarantee the circuit Safety, but for home use, there is generally no need to use such a large model of air switch. Therefore, the choice of air switch also needs to match in terms of model.
4. The function of the air switch is to protect the safe use of electricity. In the process of excessive current, once it cannot bear the load, the air switch should automatically trip to achieve the purpose of tripping. Therefore, in the selection of the air switch Whether the trip can achieve the purpose of tripping by carrying excessive current is also an important factor in the selection of the air switch.
To put it simply, the air switch tripping exists for the purpose of tripping. It is also a low-voltage switching device, so in different current processes, the tripping time will be different. For example, when the rated current is twice as high, it should automatically speak out after more than two seconds.
