Miniature circuit breaker, referred to as MCB, is the most widely used terminal protection appliance in building electrical terminal power distribution devices.
What is the production significance of miniature circuit breakers?
What is the physical principle of a miniature circuit breaker?
What are the characteristics of miniature circuit breakers?
Miniature circuit breakers refer to protective appliances installed in terminal distribution lines, mainly used for overload and short-circuit protection of lines and electrical equipment. Under the situation that the demand for electricity for national production and living continues to increase, and the society puts forward higher requirements for the safety and reliability of power supply, it is necessary to optimize the operation effect of the distribution network. To achieve this goal, it is necessary to scientifically and reasonably install the miniature circuit breaker on the interrupted distribution line to effectively protect the line and electrical equipment to avoid overload operation, resulting in a certain safety of the line and electrical equipment. harm. From this point of view, miniature circuit breakers have high application value, and it is very meaningful to actively research and develop miniature circuit breakers.
The realization of the overload protection function of the miniature circuit breaker is based on the principle that bimetals bend regularly and directionally as the temperature increases. The magnitude of the current flowing through the miniature circuit breaker is different, and the degree of bending of the bimetal is also different. In the general overload of the line, because the overload current is not too large, the tripping time of the circuit breaker is generally longer.
1. The rated short-circuit breaking capacity is high, and the rated current level of some miniature circuit breakers can reach more than 10KA.
2. The miniature circuit breaker has double wiring function, which can easily connect standard bus bar and flexible wire.
3. The miniature circuit breaker is equipped with a finger-touch protection combined terminal, which is safer.
4. The miniature circuit breaker is operated with an energy storage mechanism, and the contacts are quickly closed, which overcomes the adverse effects caused by the speed of manual operation of the handle and improves the service life of the product.
5. The miniature circuit breaker has a variety of accessories to choose from, and the modular and flexible combination is very convenient for users to install.
6. The shell and some functional parts of the miniature circuit breaker are made of high-temperature and impact-resistant plastics.
7. The current limiting coefficient of the miniature circuit breaker is high, and the performance-price ratio is superior.
After learning how to use miniature circuit breakers, we also need high-quality products to realize the production plan. How to choose the most suitable one among the many suppliers also requires careful consideration. Zhejiang Shilong Electric Technology Co., Ltd. has been a Chinese pioneer in miniature circuit breakers for several years. They can provide any connectors you need. At the same time, their after-sales service is also very considerate.
