No doubt, the smart grid construction in China is low-voltage electrical brings new technologies and market demand, low-voltage electrical appliances market prospects. China's fourth-generation low-voltage electrical products will be put on the market, will promote the technological level of low-voltage electrical industry increased to a higher level. The fourth-generation products with excellent performance, reliable, small size, combination, modular, intelligent, etc., to meet the needs of smart grid construction clients to a certain extent.

 From the above characteristics can be found in the fourth generation, the development of low-voltage electrical products, at least the following trends will be formed, that product intelligent, communications, high reliability and meet the energy requirements of environmental protection.

 Markets require high-performance, intelligent low-voltage electrical products, meant to protect low-voltage electrical products, monitoring, communication, self-diagnosis display function, which is necessary to achieve intelligent grid.

Can communicate, which means that products with a communication interface, can open a variety of two-way communication with the fieldbus, communicate and network systems.

　　　To carry out the reliability of low-voltage electrical product design, product in the production process need to be reliable control, reliability factory inspection, especially electronic device reliability and to meet electromagnetic compatibility requirements. Emphasis on environment protection and energy requirements, low-voltage electrical means to gradually develop "green" products, including reduced material selection, manufacture and use of environmental impact, as well as efficient use of energy and so on.
