what is air switch

air switch, also known as automatic air circuit breaker, is a very important electrical appliance in low-voltage distribution network and electric drive system. It integrates control and multiple protection functions. In addition to contacting and breaking circuits, it can also short circuits to circuits or electrical equipment It can also be used to start the motor infrequently

specification of household air switch

at present, DZ series air switches are used in families. The common specifications and models of air switches are as follows:

c16, C25, C32, C40, C60, C80, C100, C120 and other specifications, where C represents tripping current, that is, jump current. For example, C32 represents that the jump current is 32 A. generally, C32 is used to install 6500w water heaters, and C40 air switch is used to install 7500w and 8500w water heaters

household air switch selection

air switch is used as the main power supply protection switch or branch line protection switch in household power supply. When residential lines or household appliances are short circuited or overloaded, it can automatically trip and cut off the power supply, so as to effectively protect these equipment from damage or prevent the expansion of accidents

families generally use two pole (i.e. 2P) circuit breakers as main power protection and single pole (1P) as branch protection. If the rated current of the circuit breaker is selected to be small, the circuit breaker is easy to trip frequently, causing unnecessary power cuts. If it is selected to be too large, the expected protection effect will not be achieved. Therefore, it is very important to correctly select the rated capacity current of home mounted circuit breakers. The specifications of general miniature circuit breakers are mainly divided into 6a, 10a, 16a, 20a, 25A, 32a, 40a, 50a, 63A, 80A, 100A, etc. based on the rated current

installation of air switch

at present, there are 1-4p air switches on the market, which are selected and installed according to their own power supply mode

1p can only protect one live wire, which is suitable for lighting or the use and installation of low-power electrical appliances

2p protect a live wire and a zero wire, which can be connected to electrical appliances such as 220V motors

3p protects three live wires, which are used on 380V electrical appliances, which are rarely used in ordinary families

4p protect three live wires and one zero wire. It is also a good choice for 380V electrical appliances with zero line as the main switch

if installed, it is best to use a regular distribution box. If there is no distribution box, you can also choose a card slot for fixing the air switch in the air switch store. Fix the card slot on the board or wall, and then install the air switch on it.

editor summary: the above is the selection of household air switch, the relevant introduction of household air switch specifications, the installation error of air switch or the wrong connection of line, which may lead to short circuit of line and cause fire and other safety accidents. It can be seen that it is very important for family safety to understand the installation of air switch, the wiring method of air switch and the selection of air switch model
