What is the difference between the main switch in the low-voltage distribution cabinet of residents and other empty switches and leakage?

Commonly used circuit breakers I include air switch (device type circuit breaker), molded case circuit breaker and miniature circuit breaker (micro-break), any of which can include anti-leakage function. The anti-leakage function can be attached to the circuit breaker as a component, or it can be made into an inseparable whole with the circuit breaker.

The volume of the main switch is not necessarily larger than that of the fractional switch, and the volume of the incoming main circuit breaker of the indoor distribution box is often the same as that of the outgoing circuit breaker.

Low voltage distribution cabinet:

The rated current of the low-voltage distribution cabinet is 50Hz alternating current, and the rated voltage is 380v. Power distribution system is used for power conversion and control of power, lighting and distribution. The product has the characteristics of strong breaking ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series and practicality, novel structure and so on.

1, low-voltage switchgear and control equipment, commonly known as low-voltage switchgear, also known as low-voltage distribution cabinet, refers to a complete set of electrical devices with AC and DC voltages below1000 V.

2. With the implementation of smart grid, infrastructure, manufacturing investment and the development of new energy industry, the low-voltage distribution cabinet market in China has maintained a rapid growth trend.

3. According to the monitoring data, in 20 10, the total sales of China low-voltage distribution cabinet market was 10633 million yuan, up1.2% year-on-year; 20 1 1 year, the total sales of low-voltage distribution cabinets in China reached1196 billion yuan, up 12.5% year-on-year.

4. Under the huge market demand of low-voltage distribution cabinets in China, the competition within the industry is bound to intensify. Suppliers who provide a new generation of low-voltage complete sets of equipment and system solutions will take the lead in the future market competition. Only when enterprise products have the above characteristics can they win certain advantages in the future competition, so as to seize the commanding heights of the fourth generation of low-voltage electrical appliances.
