What can be a disadvantage of fuse and MCB?
Advantages of MCBs: MCBs have more sensitive to current then fuse. It has quick work against short circuits. It works quickly on overloading and under voltage. In the case of surge current, The MCB has time delay characteristics, therefore, it works properly.
What are advantages and disadvantages of fuses or circuit breakers?
Advantages and Disadvantages of Circuit Breakers and Fuses Fuses represent a less expensive route for overcurrent protection. They also react faster than a circuit breaker, and they are believed to be more failsafe than breakers because they contain fewer moving parts. The metal either melts or it does not.
What is the main advantage of using a fuse?
Cheapest type of protection. Current limiting effect under short circuit conditions.
What is the problem of fuse?
There are two conditions that can cause a fuse to blow. First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through.
What is the advantage and disadvantage of using a thick fuse wire?
Explanation: The resistance of a conductor is proportional to its length and inverse proportional to its cross-sectional area. So, If the fuse wires are thick, the larger cross section decreases the resistance across the fuse wire. So, even a high current flows through the fuse, it doesn’t blow out.
Do fuses go bad?
Fuses degrade with time and will eventually fail. However, do not keep replacing a fuse if it blows immediately after you replace it.
Can a blown fuse cause a fire?
Answer: Absolutely, an outlet that has blown a fuse can start a fire. If the problem was whatever was plugged into it, and that item is no longer there, there should be no problem, but if the problem was within the outlet itself it should be repaired immediately. The time to a fire could be from 2 minutes to 2 years.
What are the disadvantages of a circuit breaker?
The disadvantage to using a circuit breaker is that it can be more expensive to install, repair and replace. Circuit breakers won’t react as quickly as a fuse in power surges. This means it would be possible that electronics connected to the circuit could be damaged by energy that is just let through.
What is fuse wire class 12?
Hint: Fuse wire is safety wire (or device) connected in series with the live wire, in case of any large supply of current or malfunctioning in the electric connections it melts and breaks the electric circuit. Complete step by step answer: The Fuse wire is made by the material which can melt easily by a amount of heat.
What is a fuse wire?
A fuse is a piece of wire of a material with a very low melting point, that is, it melts and breaks as soon as its temperature gets higher than its melting point. The material used for making fuse have low melting points , hence fuse wires are mainly made up of tin, lead or zinc.
Can a fuse weaken?
Fuses degrade with time and will eventually fail. A blown fuse does not always mean that there is something wrong with the equipment, and in this article we will show you how to replace such a fuse. However, do not keep replacing a fuse if it blows immediately after you replace it.
What are the disadvantages of Fuse in circuit breaker?
The operation time of fuse can be much smaller than the operation of the circuit breaker. It is the primary protection device, against the short circuits. It is not suitable for overload, at that time fuse blow off replacing of fuse takes time. During this period of lost power. The protection of fuse is not reliable. Low breaking capacity.
What are the advantages of using a fuse element?
The fuse element change very easily. The fuse needs zero maintenance. It affords the current limiting effect under short circuit conditions. Most of the fuses are self-protecting and also they extinguishing the arc. When we use the small size of the fuse element impose a current limiting effect under short circuit conditions.
Why do we use fuse for short circuit protection?
When we use the small size of the fuse element impose a current limiting effect under short circuit conditions. Its inverse time-current characteristics enable its use for overload protection. Fuse has the ability to interrupt enormous short circuits without producing noise, flame or smoke.
What happens if you replace a fuse with a 30 amp?
Because they react slower than a fuse, appliances and electronics could potentially be damaged. Replacing a fuse requires careful attention to the amperage of the circuit. Installing a 30 amp fuse on a 20 amp circuit could ultimately lead to an electrical fire.
