Basically, use 3 type of fuse 1.

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.

What is Fuse : Different Types and Its Applications

Fuses can be considered as a sacrificial element in the circuit as they act as a weak link in the entire circuit. This is because, a fuse scarifies itself and reliably opens the circuit when there is an excessive current in the circuit or the circuit is under over load and if there is any short circuit. The principle of a fuse is based on the heating effect of the electric current. A simple fuse consists of a small conductive material with low resistance and it is placed in series with the circuit. The cross section area of this conducting material is designed such that it allows a certain amount of current that is permitted to flow in the circuit.

Fuse and Types of Fuses – Construction, Operation & Applications

Electric fuse was invented by Thomas Alva Edison in There are many types of fuses, but the function of all these fuses is the same. In this article, we will discuss the different types of fuses, its construction, working and operation and their application in various electronics and electrical systems. Related Posts:. A general Fuse consists of a low resistance metallic wire enclosed in a non combustible material. It is used to connect and install in series with a circuit and device which needs to be protected from short circuit and over current, otherwise, electrical appliance may be damaged in case of absence of the fuse and circuit breaker as they are unable to handle the excessive current according to their rating limits.

Fuses are the protectors, these are the safety devices which are used to protect the home appliances like televisions, refrigerators, computers with damage by high voltage. The fuse is made up of thin strip or strand of metal, whenever the heavy amount of current or an excessive current flow is there in an electrical circuit, the fuse melts and it opens the circuit and disconnects it from the power supply. Also, it works as a circuit breaker or stabilizer which protects the device from damage. In the market, many types, features, and design of fuses are available nowadays. Fuses are used for the prevention of home appliances from the short circuit and damage by overload or high current etc. The lives of television, computers, radios and other home appliances may also put at risk.

He was the person who suggested the utilization of reduced part of conductors to guard telegraph stations against the hits of lighting with liquefying, the slighter wires would guard equipment along with wiring in the building. In the year , lighting installations and telegraph cables can be protected by employing a variety of foil fusible essentials and wires. At the end, Thomas Alva Edison earned rights for a fuse which is an element of his electric distribution system in the year

The fuse is the current interrupting devices which break or open the circuit by fusing the element and thus remove the faulty device from the main supply circuit. The fuses are mainly classified into two types, depends on the input supply voltages they are the AC fuses and the DC fuses. The different types of the fuses are shown in the image below. The DC fuse opens or breaks the circuit when the excessive current flow through it. The only difficulty with the DC fuse is that the arc produced by the direct current is very difficult to extinct because there are no zero current flows in the circuit.

A fuse is probably the simplest electrical device, but its function is critical in protecting electrical circuits from damage. Fuses are found in every circuit in one form or another in various shapes, sizes, and ratings. In this article, we will learn how a fuse works and about the different types of the fuse.

 Понимаю.  - Стратмор хмыкнул, раздумывая, как поступить, потом, по-видимому, также решил не раскачивать лодку и произнес: - Мисс Флетчер, можно поговорить с вами минутку. За дверью. - Да, конечно… сэр.

Его редеющие седые волосы спутались, и даже несмотря на прохладу, создаваемую мощным кондиционером, на лбу у него выступили капельки пота. Его костюм выглядел так, будто он в нем спал. Стратмор сидел за современным письменным столом с двумя клавиатурами и монитором в расположенной сбоку нише. Стол был завален компьютерными распечатками и выглядел каким-то чужеродным в этом задернутом шторами помещении.

 Я-я…я убью .

Fuses can be divided into two major categories, AC fuses, and DC fuses. The below block diagram illustrates the different types of the fuse under.

There are different variants of fuse boxes available with different types of circuit breaking. For instance, in the case of slow blow fuses, a small overload is carried.
