If you want safer circuit protection, the circuit breaker is your best choice. It can escort your circuit safety at any time. With it, you don't have to worry about events such as short circuit and circuit fire. You can take a penny home safely. 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.

滅弧介質對于斷路器的構造來說是一個很關鍵的東西，它一般分為油浸式與六氟化硫，每一種斷路器的內部都會含有這其中的一種物質，當發生異常情況時，這兩種物質對于斷電起了很大的作用，他們相當于滅火器，很快的就將這場火給撲滅，在短時間內就可以化險為夷。

Arc extinguishing medium is a key thing for the structure of circuit breaker. It is generally divided into oil immersed and sulfur hexafluoride. Each circuit breaker will contain one of these substances. In case of abnormal conditions, these two substances play a great role in power failure. They are equivalent to fire extinguishers and put out the fire quickly, It can be saved in a short time.

斷路器在各個方面都會有很多的種類，依據它的動作速度，可以將它分為快速型與普通型，快速型它的性價比更高，因為它的反應速度非常的快，可以在很短的時間內將判斷出的異常情況化險為夷，對于普通型的斷路器，雖然它的效果與快速型是一樣的，但是它的反應速度與斷電速度還是要緩慢一點。

There are many kinds of circuit breakers in all aspects. According to its action speed, it can be divided into fast type and ordinary type. The fast type has higher cost performance, because its reaction speed is very fast and can turn the judged abnormal conditions into danger in a very short time. For ordinary circuit breakers, although its effect is the same as that of fast type, But its reaction speed and power-off speed are still a little slower.

快速型的斷路器在運行的時候它的內部結構非常快，所以在很多大工廠采用的都是快速型斷路器，因為工廠的功率大，普通型的斷路器無法在短時間內就將斷電處理甚好。普通型的斷路器適合在家庭電功率中使用，因為家里的電功率較低，一般是220伏左右，這個電壓對于普通型斷路器來說非常的簡單。

The internal structure of the fast circuit breaker is very fast during operation, so it is used in many large factories. Because of the high power of the factory, the ordinary circuit breaker can not handle the power failure well in a short time. Ordinary circuit breakers are suitable for use in household electric power, because the electric power at home is low, usually about 220 v. this voltage is very simple for ordinary circuit breakers.

ABB微型斷路器價格/斷路器它的體積不是很大，所以它的占地領域不大，斷路器的阻值非常的大，在電路中起到了阻礙的作用，但它與一般的阻值工具電器是不同的，因為它可以自動識別電壓的變化，然后進行自動的斷電處理，這是它的一大特性。總的說來斷路器它的作用非常的強大，購買它，就是買了一份人身保險。

ABB miniature circuit breaker price / circuit breaker its volume is not very large, so it covers a small area. The resistance value of the circuit breaker is very large, which plays an obstacle role in the circuit, but it is different from the general resistance tool electrical appliances, because it can automatically identify the change of voltage and then carry out automatic power-off treatment, which is one of its characteristics. Generally speaking, the function of circuit breaker is very powerful. Buying it means buying a life insurance.
