Question: What Is The Symbol Of Fuse?

What are the 3 types of fuses?


This is the most common type of fuse.


These fuses are specifically designed for automotive systems that run up to 32V and occasionally 42V.RESETTABLE FUSES/POLYFUSE.

Like their name suggests, these fuses are self-resetting.SEMICONDUCTOR FUSES.


What are the basic electrical symbols?

Basic Electrical SymbolsGround or Earth. A ground symbol (IEC symbol 5017) identifies a ground terminal. … Resistor. A resistor reduces current flow. … Switch. Disconnects the current when open. … Capacitor. A capacitor symbol shows two terminals running into plates. … Fuse. … Antenna. … Inductor. … Transformer.More items…

What is ACB and VCB?

ACB Stands for Air Circuit Breaker where as VCB stands for Vaccum Circuit Breaker. ACB is used for the voltage level upto 440V, whereas VCB is used beyond the 440V. Both circuit breakers differ from each other only in terms of arc quenching medium they are using.

What is a VCB breaker?

VCB stands for Vacuum Circuit Breaker. … For example, when contacts of a breaker are opened in the vacuum, the interruption occurs at first current zero with dielectric strength between the contacts building up at a rate thousands of times higher than that obtained with other types of circuit breakers.

What is the symbol for a circuit breaker?

1200 A Identifies the drawout circuit breaker represented by the symbol as a 1200 ampere circuit breaker. 225 A/3P Indicates the fixed circuit breaker represented by the symbol as a 225 ampere, three-pole breaker.

What is the symbol of motor?

This is the symbol of a generic electrical motor that is used in electrical schematics. A motor converts electrical energy into mechanical energy. This symbol represents a dual speed motor. Such type of motors has two separate windings for different speed ratios.

What is the difference between a battery and a cell?

The difference between cell and battery is that a cell is a single unit that converts chemical energy into electrical energy, and a battery is a collection of cells.

What is a cell?

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. … Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.

What is fuse short answer?

Answer: a fuse is a safety device which is damaged when large amount of electricity pass through it and it does not damage any other component when electricity reach the fuse wire the fuse wire is very thin so if amount of electricity reach it burnt and and save the other component of house.

What is HT breaker?

A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in vacuum medium. The operation of switching on and closing of current carrying contacts and interrelated arc interruption takes place in a vacuum chamber in the breaker which is called vacuum interrupter.

What is the symbol for cell?

The symbol for a battery is made by joining two more symbols for a cell together. Think of what we usually call a single battery, like the type you put in a torch. In physics, each of these is actually called a cell . It is only when you have two or more of these cells connected together that you call it a battery.

What is the symbol of relay?

A single pole switch is often denoted by the letters SP, and a double pole by DP. Relays can have one, two or more poles. Throw: The number of throws on an electrical switch is the number of positions that are available. For an electromechanical relay, there are normally only one or two throws.

Where are fuses used?

Fuses are usually used as a conduit between an electrical power source and an electrical component or a combination of components arranged in an electrical circuit. A fusible link is connected between the fuse terminals.

What is the symbol for neutral?

W️hite N in blue circle ! Neutral carries the return current – nearly as dangerous as Live. The 3rd wire is often connected to screening.
