Second, how to choose the air switch with leakage protection?
1. For home use, 10A is used for lighting, 16A is used for power socket and air conditioner respectively, and the main incoming switch 32A is similar. If there are many appliances in the room and home, you can use 50A-63A. According to the rated current of electrical appliances.
2.380V voltage of large electrical appliances, machinery, etc. So it depends on the rated current of the electrical appliance. Buy air switch according to rated current. Note: the air switch is higher than the rated current of the electrical appliance, because it is higher than the rated current when the machine is started, and the air switch is easy to trip due to overload protection.
3. General household use 1P or 2P. The difference between 1p and 2P is that 1P can only disconnect 1 live wire, and 2P can disconnect live wire and neutral wire at the same time, that is, 1P+N, so 2p is relatively better. If the rated voltage of the equipment you are loading is 220V, you can use the air switch of 1P or 2P.
4. If it is 380V, it needs 3P or 4P, and the load equipment that does not need zero connection, such as motor, fan, water pump, etc., can only choose 3P. , only use 3P air switch; If it is a 380V water boiler, water heater and other equipment, it needs 4P, and it also needs an air switch with leakage protection function to prevent leakage accidents and ensure personal safety.
The general family will install switches, but the types of installation styles are different. So what brands and selection methods are there for air switches with leakage protection? Everyone knows after reading the introduction of the above small series.
