How to choose an air switch

Last Update Time: 2018-12-06 13:34:28

The general principle of air switch selection:

The rated voltage of the air switch must be greater than or equal to the rated voltage of the line;

The rated current of the air switch and the rated current of the overcurrent release are greater than or equal to the line calculation load current.


Air switch selection is divided into two parts

Part of it is to learn how to look at the model specifications of the air switch, and the other part is to determine the air switch specifications that should be used in the home. The letter "D" in the air switch model indicates power and the letter "C" indicates illumination. At present, the family uses the air switch of the DZ series (small circuit breaker with leakage protection).


Air switch compared to traditional power switch

The air switch is a controller with a low-voltage distribution network and an electric drive system. The control and protection functions are more prominent during use. In the case of not fully contacting and breaking the circuit, the same paragraph or load for the electrical equipment To protection. In addition to this, it is also suitable to use the ground start motor. Air switch working principle: When the working current exceeds the rated current, short circuit, voltage loss, etc., the circuit is automatically cut off.


Determine the air switch model that suits your home needs

First check the size of the wire. If the wire allows a larger air switch, you can change the larger air switch, such as 1.5 square wire with C10 switch, 2.5 square wire with C16 or 20 switch, 4 square wire with C25 switch.  6 square line with C32 switch, if the wire is too small, should be given a special line for high-power electrical appliances.
