MCB：微型断路器 (MCB: Miniature Circuit Breaker)
MCB is an abbreviation of "Miniature Circuit Breaker".
MCB是“微型断路器”的缩写 。
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.
这是一个自动操作的电子开关。 它旨在通过检测电路中过大的电流来检测电路中的故障，并尽快断开电路。
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，使用保险丝代替MCB 。 熔断器需要在短路后同时更换， MCB只需复位即可开始工作。 MCB提供更好的操作安全性，适合使用。

MCB工作 (MCB Working)
On every occasion, when incessant overcurrent flows through MCB, the bimetallic strip is heated and turns aside by bending.
在每种情况下，当持续不断的过电流流过MCB时，双金属带都会被加热并通过弯曲而转向一边。
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.
双金属带的这种侧移使失去机械闩锁。 由于此机械闩锁与操作机械连接，因此成为释放微型断路器链接的基础，并且MCB以这种方式关闭，中断了电流在电路中的流动。
To resume the process and regenerate the flow of current the MCB required to be manually turned ON.
要恢复该过程并重新生成电流，需要手动将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关断的这种机制可以防止由于过电流或过载而引起的故障。 但是在短路期间，电流Swift上升，这成为与跳闸线圈或螺线管连接的柱塞的机电位移的来源。 当有效地打开断路器连杆时，柱塞撞击跳闸杆，导致闩锁机构立即释放。
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非常简单，易于使用且通常不维修。 替换起来更容易。 行程部分是关键元件，负责其适当的工作。
There are two major types of trip mechanism:
跳闸机制有两种主要类型：
- 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.
万一过热，MCB需要2秒钟至2分钟才能跳闸。
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比同时保护人类的电器保险丝要安全得多。
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，有缺陷的电线会从原始位置跳下，这使得无需花费大量精力来检测故障即可非常容易地实现。
It offers an enhanced interface by using a knob.
通过使用旋钮，它提供了增强的界面。
MCB is reusable and for this reason, is cheaper than a fuse.
MCB可重复使用，因此比保险丝便宜。
It is highly responsive to current.
它对电流具有高度的响应能力。
To make supply again, a person just has to push the knob.
要再次供应，一个人只需要按一下旋钮即可。
