Low voltage circuit breaker (called automatic switch) is a kind of not only can be switched on and off normal load current and overload current, electrical switch can switch on and off the short circuit current. Low voltage circuit breaker in the circuit of the control effect, but also has a protective function, such as overload, short circuit, under voltage and leakage protection.

Low voltage circuit breaker market experienced good growth in 2011, with the smart grid construction and the development of new energy industry, the next few years will maintain a steady growth. Mainly manifested in the following aspects:

(1) the smart grid construction large-scale spread out new demand brings

The construction of smart grid in 2020 before the three stages, the first stage is 2009-2011 years, is mainly the research and pilot; the second stage is 2011-2015, the smart grid will be large-scale implementation; the third stage is 2016-2020, the realization of perfect and improve the overall.

At present, the China State Grid Corp is stepping up efforts to develop the Chinese smart grid technology standard of nearly 200. Introduction of planning and standards, the construction of smart grid into the trip, these will give in low voltage circuit breaker, high-end huge demand.

(2) investment in manufacturing pull future growth

Manufacturing industry is the key application field of low-voltage electrical industry, energy saving and emission reduction is one of the ten key fields of engineering. China manufacturing as energy index of the pressure, the energy-saving control and intelligent power distribution electrical products will maintain strong demand.

(3) the wind energy, solar energy and other new energy to bring the huge demand for high-end, low voltage circuit breaker

After the Copenhagen conference of new energy investment becomes the focus of world attention. New energy, low carbon economy has become the main direction of electrical equipment industry. Vigorously develop new energy will constitute a great demand for efficient and stable, in the high-end products of low voltage electrical apparatus. Demand for low voltage electrical components 3-5 years is expected to increase substantially. Wind power and photovoltaic inverter control system and grid technology and a number of core, which is the key technology to be a breakthrough, low-voltage electrical industry a direction for future development.

Statistical data shows, in 2011 China's low-voltage circuit breaker industry market size for 40000000000 yuan. The next few years, with the rapid development of continuous growth of China's new generating capacity and other industry downstream, the domestic market for low voltage circuit breaker products demand will still maintain growth, therefore our country low voltage circuit breaker industry market size will grow rapidly, it is expected that in 2016 China's low-voltage circuit breaker industry market size will be close to 80000000000 yuan.

All famous foreign companies from late twentieth Century to early twenty-first Century, the launch of new ACB and MCCB, and the continuous improvement and expansion, have a major breakthrough and innovation both in the main technical performance, product structure, new technology application etc.. With the German Siemens is most prominent, the low voltage electrical communication, has to be composed of industrial system is very large, power distribution monitoring system and building automation system; MDU series circuit breaker Mitsubishi Co to develop, can directly realize the power energy monitoring network system, equipment monitoring network system.

Low voltage electrical appliances are widely used in various industries of the national economy, the close contact with the conditions of the whole social fixed investment. 21 the beginning of the actual is the rapid development of China's low-voltage electrical industry, China's low-voltage electrical industry in recent years the growth rate remained at 10%-15%. Low-voltage electrical industry market capacity and power, industry, real estate, the telecommunications industry is closely linked, the potential demand coupled with low-voltage electrical demand structure adjustment and the international market, to provide the broad space for the future development of low-voltage electrical industry.

During the 12th Five Year Plan period, with the development of intelligent power grid construction and the promotion of the low-voltage electrical production technology, with intelligent, modular, communication is a new generation of low-voltage electrical appliances, the main feature of the market will become mainstream products. The first generation of products will be withdrawn from the market in 2010, the second generation of products will become the low-end products, the third generation of products and part of the second generation of products will become in the end product. From 2011 to 2015, the smart grid will become the seven electric, distribution, communication in the transmission, entered the construction phase.
