- Fuse (electrical)
It is made of porcelain, glass or porcelain.
A Fuse is an electrical device made up of glass, porcelain or plastic material containing a thin piece of wire. If any faults occur in the system and an over current flow through the circuit, the fuse automatically melts and breaks the contact of the circuit. Thus, protecting the appliances from any damage. The Circuit Breaker also performs the similar function as that of the fuse but by electromagnetism principle.

The MCB and a normal fuse have the same function. Both, are used to prevent the circuit from an excess flow of current resulted due to short circuit or overload. When the current flow exceeds a fuse wire burns out in order to open the circuit. Where an MCB disconnects the circuits by tripping. Tags: fuse. August 9,
Fuses and Circuit Breakers both serve the same purpose — which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity. Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. Fuses come in different types — for both residential and commercial use. The most common type is made from a metal wire or a filament that is enclosed in a glass or ceramic and metal casing. When electricity flows, the fuse will permit the power to pass unobstructed across the filament between circuits.

In electronics and electrical engineering , a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device ; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type. Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity, and response times, depending on the application.
Although both are circuit breakers, there are actually key differences between the two that make them specially made for specific jobs. However, before we talk about the key features of each, it is important to understand what the abbreviation s stand for. The main difference between the two is their capacity, with the MCB rated under amps with an interrupting rating of under 18, amps. Consequently, their trip characteristics may not be adjusted since they basically cater to low circuits. On the other hand, an MCCB comes with an adjustable trip characteristic for the higher models. Usually, this type of circuit breaker would provide amps as high as 2, or as low as 10, depending on what is necessary. Their interrupting rating ranges from around 10, amps to , amps.
Normally, the ampacity rating of a conductor is a circuit design limit never to be intentionally exceeded, but there is an application where ampacity exceedance is expected: in the case of fuses. A fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current. Fuses are always connected in series with the component s to be protected from overcurrent, so that when the fuse blows opens it will open the entire circuit and stop current through the component s.
Electrical Academia. A fuse and circuit breaker both of them protect an overloaded circuit by disrupting the current continuity. The way they disrupt the current flow is dissimilar. A fuse is a simple piece of metal that melts down when overheated because of excessive flow of current whereas a circuit breaker has switching mechanism that is activated when unsafe current flows through the circuit.
Circuit protection devices such as fuses and MCBs are used to safeguard any equipment from damages caused due to short circuits. The usage of these devices does not mitigate the chances of occurrence of a fault. But can help us prevent the undesirable aftermaths of the electrical faults.
The most dependable and prominent power source for humankind for many years was electricity.

К рабочему кабинету Стратмора, именуемому аквариумом из-за стеклянных стен, вела узкая лестница, поднимавшаяся по задней стене шифровалки. Взбираясь по решетчатым ступенькам, Сьюзан смотрела на массивную дубовую дверь кабинета, украшенную эмблемой АНБ, на которой был изображен могучий орел, терзающий когтями старинную отмычку. За этой дверью находился один из самых великих людей, которых ей довелось знать. Пятидесятишестилетний коммандер Стратмор, заместитель оперативного директора АНБ, был для нее почти как отец. Именно он принимал ее на работу, именно он сделал АНБ для нее родным домом. Когда десять лет назад Сьюзан поступила в агентство, Стратмор возглавлял Отдел развития криптографии, являвшийся тренировочной площадкой для новых криптографов, криптографов мужского пола.
