電路安裝過程中，需要配置不少設施，斷路器就是一種，那斷路器是什么東西呢？使用時又要注意什么呢？下面就來簡單了解一番吧。

　　Circuit installation process, need to configure a lot of facilities, circuit breaker is a kind of, that circuit breaker is what? What should we pay attention to when using it? Here's a brief look.

　　斷路器就是用來斷開電路的器械裝置，它主要是作用于電力輸送和使用中，在配電環節中必不可少，能避免電壓荷載過大導致的電路損壞、用電設備損壞等等問題。一旦電流過大，或者出現短路、欠壓等故障時就會自動切斷電路來保障安全。

　　Circuit breaker is used to disconnect the circuit device, it is mainly used in power transmission and use, essential in the distribution link, can avoid voltage load caused by excessive circuit damage, electrical equipment damage and so on. Once the current is too large, or short circuit, undervoltage and other faults will automatically cut off the circuit to ensure safety.

　　要注意選擇合適的斷路器。斷路器本身的型號參數不少，在安裝時要搭配好才行，可以根據電壓、電流和用電設備來選擇，否則選小了，會出現沒到額定電流就跳閘，頻繁跳閘會影響到正常使用，選大了就會出現超過負荷也不跳閘，導致電路燒損或用電設備損壞，可以搭配1.25倍額定電流的斷路器。

　　Care should be taken to select a suitable circuit breaker. Model parameters of the circuit breaker itself, when installation should match well, can choose according to the voltage, current and power equipment, or choose the small, there will be no trip to the rated current, frequent trip will affect the normal use, choose the big trip, there will be more than load circuit loss or damage to the electrical equipment, Can be used with circuit breakers of 1.25 times rated current.

　　注意安裝環境。斷路器雖然使用廣泛，但是對于周圍空氣溫度、大氣條件和污染等級都是有要求的。不能安裝在溫度超過40度、低于零下5度的環境，而且周圍空氣溫差不能過大，要是一天以內溫差超過30度的話，就無法使用。

　　Pay attention to the installation environment. Although circuit breakers are widely used, they are required for ambient air temperature, atmospheric conditions and pollution levels. It should not be installed in an environment where the temperature is more than 40 degrees Celsius and less than minus 5 degrees Celsius, and the temperature difference in the surrounding air should not be too large. If the temperature difference exceeds 30 degrees Celsius within a day, it cannot be used.

　　斷路器也不能安裝在氣壓過低的區域，譬如說海拔超過2000米的位置就無法使用。同時對于濕度也有一定的要求，濕度在40%-50%為宜，不要超過90%，或者不要低于25%。斷路器不能安裝在污染太高的區域，在3級以內都可以使用。

　　The circuit breaker should not be installed in areas where the air pressure is too low, such as over 2000 meters above sea level. At the same time, there are certain requirements for humidity, humidity in 40%-50% is appropriate, not more than 90%, or not less than 25%. Circuit breakers should not be installed in areas that are too polluted. They can be used up to level 3.

　　ABB塑殼斷路器代理人員提醒大家還要注意安裝要平穩。斷路器很多部位是塑料材質的，很容易出現脫扣情況，會影響到使用，一定要平穩安裝才行。
