With the development of society, leakage switch is now a necessity for home decoration. Leakage switch, mainly used to prevent leakage accidents, plays an important role in our life. Today, Xiaobian will give you detailed information about how to select ABB circuit breaker.

abb斷路器要如何選擇？

How to select ABB circuit breaker?

1、首先要在選用時(shí)要與電源的額定電壓相同，如果不一致的額定電壓使用時(shí)會(huì)出現(xiàn)短路問(wèn)題；

1. First of all, it should be the same as the rated voltage of the power supply. If the inconsistent rated voltage is used, there will be a short circuit problem;

2、選用的斷路器的額定電流不能小于電路中的額定電流，作為一個(gè)可以閉合和斷開(kāi)電流的開(kāi)關(guān)裝置，如果額定電流過(guò)小，那么問(wèn)題就大了；

2. The rated current of the selected circuit breaker shall not be less than the rated current in the circuit. As a switching device that can close and disconnect the current, if the rated current is too small, the problem will be serious;

3、電路發(fā)生短路時(shí)，其額定斷開(kāi)電流不能小于電路的短路電流，才可以及時(shí)有效地開(kāi)斷電流；

3. In case of short circuit, the rated breaking current shall not be less than the short-circuit current of the circuit, so that the breaking current can be timely and effectively;

4、選擇時(shí)還要參照周圍的環(huán)境條件，如溫度、濕度、高度、有無(wú)粉塵和腐蝕環(huán)境這些都會(huì)影響斷路器的使用，所以要嚴(yán)格按照要求來(lái)選，例如，在 拔地區(qū)建議選用真空式斷路器，一般不采用六氟化硫因?yàn)闀?huì)受到海拔高度和大氣壓的影響而液化造成滅弧能力下降；

4. The selection shall also refer to the surrounding environmental conditions, such as temperature, humidity, height, whether there is dust and corrosive environment, which will affect the use of the circuit breaker, so it shall be selected in strict accordance with the requirements. For example, it is recommended to select the vacuum circuit breaker in the pull-out area. Generally, sulfur hexafluoride is not used, because it will be liquefied under the influence of altitude and atmospheric pressure, resulting in the decline of arc extinguishing capacity;

5、根據(jù)不同的負(fù)載選用不同類型的斷路器，一般來(lái)說(shuō)，計(jì)算電流乘以1．25能夠確定整定電流，然后選用適合的斷路器，之后才能選用電線；

5. Select different types of circuit breakers according to different loads. Generally speaking, the setting current can be determined by multiplying the calculated current by 1.25, and then select appropriate circuit breakers before selecting wires;

6、根據(jù)市場(chǎng)上的品牌來(lái)選擇質(zhì)量、性價(jià)比比較好斷路器，質(zhì)量越好，安全使用性便越高，不易出現(xiàn)故障等問(wèn)題，千萬(wàn)不要為了貪便宜而選用雜牌，沒(méi)有一份保障，使用起來(lái)難免不放心。

6. Select the circuit breaker with good quality and cost performance according to the brands in the market. The better the quality, the higher the safety and use, and it is not easy to have problems such as failure. Don't choose miscellaneous brands for the sake of cheap. Without a guarantee, you will inevitably feel uneasy when using them.
