In recent years, the low-voltage electrical industry has experienced remarkable growth opportunities. It is estimated that from 2001 to 2010, the annual installed capacity will reach 21 GW. Based on empirical matching ratios, approximately 480,000 low-voltage frame circuit breakers and 4.82 million molded case circuit breakers are required each year. Moreover, with government encouragement for the export of mechanical and electrical products, the export volume has been steadily increasing. As a result, the Chinese low-voltage electrical market is vast and continuously expanding, offering very promising future prospects.
Market Structure
Domestic companies have advanced to produce the third generation of low-voltage electrical products, while foreign manufacturers have already introduced the fourth generation. China's low-voltage electrical industry has evolved from simple assembly and imitation manufacturing to self-developed design. Companies like ABB have developed nearly 1,000 series of low-voltage products, with around 1,500 production enterprises generating an annual output value of about 20 billion yuan.
However, most domestic manufacturers are small in scale, and there are over 90% of them producing medium- and low-end products repeatedly. The market currently sees three generations of products coexisting. According to output value, first-generation products hold a 15% market share, second-generation products account for 45%, and third-generation products make up 40%. With national policy driving further structural adjustments, outdated, energy-intensive, and environmentally harmful products will be phased out. By 2010, first-generation products are expected to be eliminated, second-generation products will move to the low-end segment, and third-generation products will gradually become mid-range offerings.
While China was accelerating the development and market launch of its third-generation products, several well-known foreign manufacturers introduced their next-generation solutions in the late 1990s and early 2000s. These include frame circuit breakers such as Schneider’s MT series, Siemens’ 3WL series, ABB’s E series, GE’s M-PACT series, and Kamax’s Magnum series. For molded case circuit breakers, notable models include Schneider’s NS series, Siemens’ 3VL series, ABB’s Tmax series, GE’s Record Plus series, Moeller’s NZM series, Kamax’s G series, and Mitsubishi’s WS series.
These new-generation products are characterized by high performance, electronic features, intelligence, modularity, combination capabilities, and miniaturization. They also incorporate communication functions, high reliability, ease of maintenance, and environmental compliance. Most importantly, they can be integrated into fieldbus systems, enabling full system networking and marking a significant functional advancement in low-voltage electrical equipment.
