斷路器是配電系統中主要的保護電器之一，其主要作用是作為短路、過載、接地故障、失壓以及欠電壓保護，但是很多人分不清它和漏電保護器有什么不一樣，下面我們就來講講吧。

　　Circuit breaker is one of the main protection appliances in the distribution system, its main role is as a short circuit, overload, grounding fault, loss of voltage and under voltage protection, but many people can not distinguish it and leakage protector what is not the same, let's talk about it.

　　微型斷路器由操作組織、觸點、維護設備（各種脫扣器）、滅弧體系等構成。其主觸點是靠手動操作或電動合閘的。主觸點閉合后，悠閑脫扣組織將主觸點鎖在合閘方位上。過電流脫扣器的線圈和熱脫扣器的熱元件與主電路串聯，欠電壓脫扣器的線圈和電源并聯。

　　The MCB consists of operation organization, contacts, maintenance equipment (various tripping device), arc extinguishing system, etc. The main contact is manually operated or electrically closed. After the main contact is closed, the leisure tripping organization locks the main contact on the closing direction. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply.

　　當電路發作短路或嚴峻過載時，過電流脫扣器的銜鐵吸合，使悠閑脫扣組織動作，主觸點斷開主電路。當電路過載時，熱脫扣器的熱元件發熱使雙金屬片上曲折，推進悠閑脫扣組織動作。當電路欠電壓時，欠電壓脫扣器的銜鐵開釋。也使悠閑脫扣組織動作。

　　When the circuit is short-circuited or severely overloaded, the armature of overcurrent tripping device is closed, so that the loose tripping organization acts, and the main contact disconnects the main circuit. When the circuit is overloaded, the heat element of the thermal release device heats up and twists on the bimetal sheet, promoting the leisurely release organization action. When the circuit is undervoltage, the armature of undervoltage release. Also allows for leisurely tripping to organize movements.

　　斷路器的功能相當于熔斷器式開關與過欠熱繼電器等的組合。漏電保護器則具有過載和短路保護功能，可用來保護線路或電動機的過載和短路，亦可在正常情況下作為線路的不頻繁轉換啟動之用。

　　The function of the circuit breaker is equivalent to the combination of fuse switch and overheat relay. Leakage protector has overload and short circuit protection function, which can be used to protect the overload and short circuit of the line or the motor, and can also be used as the infrequent conversion of the line under normal circumstances.

　　低壓斷路器的功能相當于閘刀開關、過電流繼電器、失壓繼電器、熱繼電器及漏電保護器等電器部分或全部的功能總和，是低壓配電網中一種重要的保護電器。

　　The function of low-voltage circuit breaker is equivalent to knife switch, over-current relay, voltage loss relay, thermal relay and leakage protector and other electrical parts or all the functions of the sum, is an important protection of low-voltage distribution network.

　　漏電保護器有對漏電流檢測和判斷的功能，而不具有切斷和接通主回路功能，這一點跟低壓斷路器不一樣。另外，ABB微型斷路器價格不會很一樣，受市場以及需求量的影響而變化。

　　Leakage protector has the function of leakage current detection and judgment, and does not have the function of cutting off and connecting the main circuit, which is different from the low-voltage circuit breaker. In addition, ABB MCB prices will vary depending on the market and demand.

　　如果在不同場所中，出現間接觸電問題，給人體造成損傷是不一樣的，因此需要按照場所的實際情況來選擇相應的斷路器產品。針對比較容易出現漏電問題的場所，應挑選比較靈敏的產品，相比干燥空間，潮濕空間更容易出現觸電問題，因此要選擇安裝電流合適的機器。

　　If in different places, indirect electric shock problem, damage to the human body is not the same, so need to choose the corresponding circuit breaker products according to the actual situation of the place. For places prone to leakage problems, sensitive products should be selected. Compared with dry space, electric shock is more likely to occur in wet space, so it is necessary to choose a machine with appropriate current.
