Various Types of Fuse!!! And How it works???



  • We know that the main function of fuse is the protection of electrical equipments against high load current and any fault.

  • There are generally three types of Fuse which is shown below

  1. Rewireable Type Fuse
  2. Cartridge Type Fuse
  3. H.R.C. Type Fuse
  • All the the three types are described in detail below....

1. Rewireable Type Fuse

Kit kat type fuse
KitKat Fuse | Types of Fuse
  • This type of fuse commonly used in house wiring. It is also known as kit kat type fuse.

  • This type of fuse made of two porcelain parts

  1. Base and
  2. Fuse carrier

  • The base is connected with switch board.

  • Incoming wire is inserted from the one side and directly connected to the terminal wire.

  • Outgoing terminal is taken from the other terminal and also is called onward connection.

  • In base area, two terminal are connected through fuse wire which held in the fuse carrier.

Advantages of rewireable Type Fuse

  • Replacement of fuse is very easy.
  • Negligible cost
  • Removal of fuse is very easy

Disadvantages of rewireable Type Fuse

  • Breaking capacity is very low.
  • We can't use it for high current.
  • True value of fuse element is very difficult to determine.

2. Cartridge Type Fuse

Cartridge fuse
Cartridge Fuse | Types of Fuse 

  • This type of fuse have a totally enclosed area like a tube shape.

  • The fuse wire is carried by the container and fill with powder which is sealed at its endside with metallic material.

  • The perfect insulating path is provided by the power for the fuse which helps to absorb the arc when the blowing up of fuse.

  • This type of fuse generally used at 415v power supply.

Advantages of Cartridge Fuse

  • More accurate
  • The fuse element is non-deterioration.

Disadvantages of Cartridge Fuse

  • Cost is high for replacement
  • This type of fuse is not very economical.

3. High Rupturing Capacity Fuse 

H. R. C. Fuse
H R C type fuse | Types of Fuse

  • This type of fuses are used for heavy load at distribution system where heavy current can be flow.

  • This type of fuse know as HRC Fuse very well.

  • Operation of this type of fuse is very fast and also it will be absorb the heat very fast which is produced by the arc.

  • HRC fuse consists ceramic cylinder ahaps body which resist the heat and consist heavy copper contacts at main body.

  • Cylindrical body filled with non combustible powder which absorb the arc.

Advantages of HRC Fuse

  • More accurate rating.
  • High current breaking safely.
  • Operation is very fast.

Disadvantages of HRC Fuse

  • It will need to replace after each operation.
  • So very costly.

Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino

Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction To Arduino Arduino is an Italian company that designs and manufactures Open Source Hardware (Microcontroller) and Open Source software or IDE (Integrated Development Environment). Arduino hardware is such a programmable computerized platform, by working on which the user can combine the hardware and software and prepare the electronic brain according to his own and can control the electronic devices from that electronic brain. What is arduino? If you want to understand more easily, then we can say that Arduino microcontroller is an empty brain, in which you can upload memory by coding or programming through arduino software, so these are called open source. Arduino works like a CPU of a board computer. Right now the microcontroller of the arduino of this time that we can take up is lik

What is Microprocessor? | Block Diagram of Microprocessor | Application of Microprocessor What is Microprocessor? | Block Diagram of Microprocessor | Application of Microprocessor Basic Detail Of Microprocessor The  microprocessor is a semiconductor device consisting of electronic logic circuits manufactured by using either a large scale(LSI) or very large scale integration(VLSI) technique. The microprocessor is capable of performing computing functions and making decisions to change the sequence of program execution. In large computers, the central processing unit(CPU) performs these computing functions and it is implemented on one or more circuit boards. The microprocessor is in many ways similar to the CPU, however, the microprocessor includes all the logic circuitry(including the control unit)on one chip. The microprocessor consists of the following three segments which is shown in below diagram. Block Diagram of Microproce

What is Instrumentation? And Modes of Measurement

What is Instrumentation? And Modes of Measurement Definition of Instrumentation The technology of using instruments to measure and control the physical and chemical properties of materials is called “ instrumentation ". What is Instrumentation? And Modes of Measurement When the instruments are used for the measurement and control of industrial manufacturing , conversion or treatment processes, the term process instrumentation is applied. When the measuring and controlling instruments are combined so that measurements provide impulses for remote automatic action, the result is called a control system. Modes of Measurement There are the three modes of measurement: 1. Primary Measurement 2. Secondary Measurement 3. Tertiary Measurement All the three modes are described below: (1) Primary Measurements In the primary measurement sought value of a parameter is determined by comparing it directly with reference standar
