What is the development prospect of intelligent mini Circuit breaker?

When it comes to the intelligent circuit breaker in China, the development and current situation of the low-voltage circuit breaker in China have to be mentioned. Low-voltage circuit breaker is one of the most complex low-voltage electrical appliances, the highest technical content and economic value, and the most important products in low-voltage distribution system.

Intelligent Circuit breakers — Development background

The technical level, output and quality of ACB and MCCB products of a manufacturer rank in the industry to some extent, representing the position of the enterprise in the low-voltage electrical appliance industry. The output value of low-voltage circuit breaker accounts for more than 50% of the total output value of low-voltage electrical appliances. In our country the leakage electric appliance and small circuit breaker begin to develop from 1970′s, and small circuit breaker is still widely promoted in our country after 1990′s.

Three generations of universal circuit breaker and plastic-case circuit breaker have been developed since the early 1960s. The low-voltage vacuum circuit breaker has been developed since the end of 1990s, and DK5-630 ~ 2500A series of vacuum circuit breakers have been developed and popularized. However, the product structure and technology need to be further improved, and the product performance is expected to be further improved. Since the DC fast circuit breaker was updated in the late 1980s, it has not been developed for a new generation of products due to the limited use occasions. This paper focuses on the analysis of universal circuit breaker, plastic-case circuit breaker and miniature circuit breaker status and development trend.

Intelligent mini circuit breaker – Product division

According to the development history of the industry, ACB has developed three generations of products, the first generation product DW10, the second generation product DW15 (independently developed), the introduction of ME, AH, 3WE, AES. The third generation product DW45 (developed by itself) is the most successfully promoted product with the best reliability and economic benefits in the history of low-voltage electrical apparatus development in our country. In the same period, M, F, 3WN6, AE-SS, MAGNUM, M-Pact and other series products were introduced. DW16 series is the first generation of secondary development products, DW15HH is the second generation of secondary development products, DW450 is the second generation of secondary development products.

At present, three generations of products coexist, and the first generation of DW10 is eliminated and replaced by DW16. In 2008, the total number of ACBs exceeded 600,000. The proportion of the third generation products by the number of units accounted for 45%, according to the output value of 80%. Major domestic manufacturers: Shanghai People, Changshu Switch, Zhejiang swtich, Tianjin Baili, Long March 9 Factory, Shanghai Lean, Jiangsu Kaifan, Kailong, Zhejiang Switch Factory, Chint, Delxi, Tianzheng, etc., more than 100 production enterprises. ACB product technical analysis: At present, the domestic high-end products (the third generation and improved type) from the technical level of the gap is not big with foreign products. From the quality level: a few excellent enterprises product quality and foreign advanced level close to the majority of enterprises product quality gap.

Intelligent Mini Circuit breaker – Product market analysis

Domestic products of high, medium and low grade specifications, varieties of products complete, can meet the domestic grade especially the middle and low market demand. Due to the importance of ACB products in the power distribution system, foreign-funded enterprises almost dominate the main switch market of key engineering projects by using its brand, quality, performance and product personalization, appearance and reliability.

In summary, said so much is nothing more than to introduce the development and current situation of the low-voltage circuit breaker in our country. Businesses in the purchase of intelligent small circuit breaker can be understood from many angles, the current product demand trends in the market. I hope this will help you.
