If you want more safe circuit protection, the circuit breaker is your best choice. It can protect your circuit safety at any time. With it, you don't have to worry about short circuit, circuit fire and other incidents anymore. You can take it home safely for a penny. The use categories of circuit breakers are also divided into two categories, the first is selective type, and the second is non selective type. For these two types, they should also be selected according to the situation.

Arc extinguishing substance is a very important thing for the structure of the circuit breaker. It is divided into oil immersed type and sulfur hexafluoride. Each circuit breaker contains one of these substances. When abnormal conditions occur, these two substances play a great role in powering off the power. They are equivalent to fire extinguishers. The fire can be put out quickly and saved in a short time.

There are many kinds of circuit breakers in all aspects. They can be divided into fast type and ordinary type according to their action speed. The fast type has a higher cost performance, because its reaction speed is very fast, and the abnormal situation can be eliminated in a very short time. For the ordinary type of circuit breaker, although its effect is the same as that of the fast type, its reaction speed and power-off speed should be slow.

The internal structure of the fast type circuit breaker is very fast when it is running, so many large factories use fast type circuit breakers. Because of the high power of the factory, the ordinary type circuit breakers cannot handle the power failure in a short time. Ordinary circuit breakers are suitable for use in household electric power, because the electric power in the home is low, about 220 volts. This voltage is very simple for ordinary circuit breakers.

The volume of the circuit breaker is not very large, so it does not cover a large area. The resistance value of the circuit breaker is very large, which acts as an obstacle in the circuit. However, it is different from the general resistance tools and appliances, because it can automatically identify the changes in voltage, and then conduct automatic power off processing, which is a major feature of the circuit breaker. In general, the circuit breaker is very powerful. To buy it is to buy a life insurance.
