A fuse protects a circuit from short circuiting. Also a breaker is used for this same purpose with the additional advantage of protecting the circuit from overloads also.

Is a circuit Protection device made from special metals that shut off a switch if too much current flows through a circuit and there is a risk of overloading or overheating the circuit?
The (only) protection device which works like that is a fuse. It is simply a short length of metal which melts when too much current flows through it.
How can short circuit damage devices?
It depends if the short are before or after the device. The short circuit will cause high amperage trough the device and then blown. (JP)
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
Short circuit bar on the railway?
What is the question? Assuming you're talking about short circuiting the live circuit, as soon as a phase to ground fault occurs protection will operate, opening a circuit breaker.
Why are the live wire and neutral wire never joined together?
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
Which is the most important device to protect electric circuits from the harm caused by short circuit and overloading?
There are two main devices. One is the circuit breaker. It provides a dual function where in it can detect short circuits with its internal magnetic sensor and overloads with its internal bi metallic strip. The other device is a fuse. It operates by melting a fusible link, that breaks the fault current that is in the circuit, when a high current rush through the fuse.

What will happen to a safety device if there is short circiut?
If your reference to a safety device is a fuse, then if there is a short circuit, the circuit will be de energized by the opening of the fuse.
What fuses and circuit breakers provide protection in the event of?
Short circuit fault.
How a fuse can provide time delayed protection for normal overload and high speed protection for short circuit?
There are two sections of the fuse; a straight wire section that provides quick acting response to short circuit conditions, and a coiled spring section with a soldered lump with thermal mass that provides time delay for normal overload. When inspecting a blown fuse, you can tell if it was a short or an overload by looking at where the blowout occurred.
What do car fuses do?
A device designed to provide protection for a given circuit or device by physically opening the circuit. Fuses are rated by their amperage and are designed to blow or open when the current being drawn through it exceeds its design rating. They are designed to protect the electrical circuits in your car from a short circuit or overload.
Why fuse will get burnt when phase and neutral get connected?
A fuse is an overcurrent protection device, which protects a circuit by melting in the event of either a sustained overload current, or a short-circuit current. A short-circuit current will occur when a line (not 'phase') conductor makes direct contact with a neutral (or earth) conductor.
What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
What is exactly answer of circuit breaker?
A circuit breaker is an overcurrent protection device. As well as being able to open and close a circuit supplying its rated load, a circuit breaker must also be capable of interrupting and closing onto an overcurrent, including a short-circuit fault, without damaging itself.
What is the electrical protection against short circuit?
By providing high insulation.....
