1, follow the direction of the large to small Selection. Air switch if the home, then just consider whether the home can carry the current, including the living room, bedroom, kitchen, bathroom, the total rated current, if not home, it is more necessary to choose from the direction of the large to small, which will ensure that the air switch can withstand a larger current, will not occur in the case of current short-circuit and so on.
2, in the purchase of air switches before, be sure to first figure out your incoming switch as well as the circuit switch. The so-called entry switch is the unit downstairs of the total meter to the home of the line, look at the total rated current, look at the maximum load current in the home, to determine a minimum rated current value, while the circuit switch is the home circuit, must be from the positive pole in the return to the negative pole, the formation of a circuit of the process, in short, a circuit to connect the power supply. These two aspects are also to be used as a selection aspect of the air switch to reference.
3, after knowing the current of their homes, the next, is the air switch model selection. According to my understanding, the air switch model has the following types, DZ47, DZ10, DZ5, DZ15 and DZ20 several air switch models of which DZ5 is the smallest, applicable to the rated current 50A circuit, DZ47 applies to the current of 60A, as well as 240v/415v below the operating voltage, the largest model of this air switch applies to building Circuit, the largest of which should belong to the four air switches, its rated current reached 630A, 400v below the working voltage, can guarantee the safety of the circuit, but home, 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.
4, the role of the air switch is to protect the safety of electricity, in the process of too large a current, once the bearer can not afford, the air switch should be automatically released, to achieve the purpose of tripping, so in the selection of air switches, whether the release can be based on the bearer of excessive current to achieve the purpose of the tripping, this is also the selection of air switches is an important factor.
Simply put, the existence of the air switch release is to trip, but also a low-voltage switching device, then in the process 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.
