MCB：微型斷路器 (MCB: Miniature Circuit Breaker)
MCB is an abbreviation of "Miniature Circuit Breaker".
MCB是“微型斷路器”的縮寫 。
It is an automatically operated electronics switch. It is designed to detect the fault in the electrical circuit by detecting the extreme amount of current flow in the circuit and breaks the circuit as soon as possible.
這是一個自動操作的電子開關。 它旨在通過檢測電路中過大的電流來檢測電路中的故障，并盡快斷開電路。
In the beginning, fuses were used in place of MCB. Fuses require being substitute after a short circuit at the same time MCB just has to be reset and it will start working. MCB provides better operational safety and is suitable to use.
最初，使用保險絲代替MCB 。 熔斷器需要在短路后同時更換， MCB只需復位即可開始工作。 MCB提供更好的操作安全性，適合使用。

MCB工作 (MCB Working)
On every occasion, when incessant overcurrent flows through MCB, the bimetallic strip is heated and turns aside by bending.
在每種情況下，當持續不斷的過電流流過MCB時，雙金屬帶都會被加熱并通過彎曲而轉向一邊。
This turning aside of bimetallic strip let lose a mechanical latch. As this mechanical latch is connected with the operating machinery, it becomes a basis to release the miniature circuit breaker links, and the MCB switches off in that way discontinuing the current to flow in the circuit.
雙金屬帶的這種側移使失去機械閂鎖。 由于此機械閂鎖與操作機械連接，因此成為釋放微型斷路器鏈接的基礎，并且MCB以這種方式關閉，中斷了電流在電路中的流動。
To resume the process and regenerate the flow of current the MCB required to be manually turned ON.
要恢復該過程并重新生成電流，需要手動將MCB接通。
This mechanism of MCB switch off protects from the faults taking place due to over current or overload. But for the period of short circuit situation, the current goes up rapidly, which becomes a source of electromechanical displacement of plunger connected with a tripping coil or solenoid. The plunger hits the trip lever causing the instant release of the latch mechanism as an effective open the circuit breaker links.
MCB關斷的這種機制可以防止由于過電流或過載而引起的故障。 但是在短路期間，電流Swift上升，這成為與跳閘線圈或螺線管連接的柱塞的機電位移的來源。 當有效地打開斷路器連桿時，柱塞撞擊跳閘桿，導致閂鎖機構立即釋放。
An MCB is very simple, easy to use and is not commonly repaired. It is just easier to substitute. The trip section is the key element, which is in charge of its suitable working.
MCB非常簡單，易于使用且通常不維修。 替換起來更容易。 行程部分是關鍵元件，負責其適當的工作。
There are two major types of trip mechanism:
跳閘機制有兩種主要類型：
- A bi-metal offers protection against overload current.
- An electromagnet offers protection against short-circuit currents.
In case of overheating MCB takes 2 seconds to 2 minutes to trip.
萬一過熱，MCB需要2秒鐘至2分鐘才能跳閘。
MCB功能 (MCB Features)
Managing MCB is much secured than a fuse for electrical appliances at the same time for human beings also.
管理MCB比同時保護人類的電器保險絲要安全得多。
In MCB, defective wire trips off from an original place which makes it very much achievable without enormous effort to detect faults.
在MCB中，有缺陷的電線會從原始位置跳下，這使得無需花費大量精力來檢測故障即可非常容易地實現。
It offers an enhanced interface by using a knob.
通過使用旋鈕，它提供了增強的界面。
MCB is reusable and for this reason, is cheaper than a fuse.
MCB可重復使用，因此比保險絲便宜。
It is highly responsive to current.
它對電流具有高度的響應能力。
To make supply again, a person just has to push the knob.
要再次供應，一個人只需要按一下旋鈕即可。
