First, the brand of air switch with leakage protection
1, Schneider Electric (China) Co., Ltd. is a leading brand in the field of power distribution equipment in the world. The brand has a glorious history of 170 years, and is a famous manufacturer in the electrical field, focusing on providing customers with safe, reliable and efficient energy. Top ten brands of switch sockets and top ten brands of electrical equipment-electrician.
2.ABB, ABB is a global leader in power and automation technology, focusing on providing solutions for customers in the industrial and power industries. This brand belongs to the top ten brands of electrical equipment, and it is also the first manufacturer of self-cooling transformer, high-voltage DC transmission technology and the first industrial robot in the world.
3. Zheng Tai Zhengtai and Zhejiang Zheng Tai Electric Appliance Co., Ltd. are the largest manufacturers of low-voltage electrical appliances in China. This is also a company specializing in the research, development, production and sales of low-voltage electrical products such as distribution appliances, control appliances, terminal appliances, power appliances and power electronics. It is one of the top ten brands of electrician and one of the top ten brands of electrical equipment in China.
4.

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 to be connected to zero, 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 above content is about the brand of air switch with leakage protection and how to choose air switch with leakage protection. I believe that after reading it, you will know more or less.
