What exactly is the difference between a surge protector and a fuse? Can a fuse protect the electronic devices from lightning instead of surge protector?

The bolt then partially travels down the line to your home.
This device then solves the entire problem.
so, what happens?

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
At the secondary, it is 1000 times less.)turns ratio). If it gets hit with a 100,000 volt bolt of lightning then the voltage arrestors conduct and clamp the voltage down to line voltage, ( but a small amount leaks down the line). This is the problem.

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
This one hit behind the barn.

A circuit breaker is similar, but is resettable.
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

“ A surge suppressor is the one which is connected at the input supply so that when there is a sudden change voltage it bypasses thereby protecting the (circuit) and electronic components”
It seems Mohan does not understand the difference between a comment and an Answer.
The MOV will conduct when the voltage exceeds 50% of line voltage.

Now when you have a certain ac resistance, then a current flows in a loop.

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
This is a high voltage low current spike that comes down the line because of the power poles being struck, and the voltage suppressors activating on the primary side of the transformer.

One is “what exactly is in a ‘surge protector’ ? ”
It also is a device that limits the change in current flow.
There are three different concepts here that are getting confused.
An AC voltage/ current source, and an ac inductive load.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
but I think this circuit , shows a few more pieces.
Because the load is inductive, the current lags the voltage.(by a bit).
These are simplified answers to the original question, and does not change anything I wrote above.
Barnstars:
This is where the MOV conducts again, and dissipated the energy.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
The other is “what does a “fuse” do?”
the problem then depends on "how fast does the fuse operate?".
So, the voltage could go up to 500 volts, and the fuse will not open up.
At least they know the answer if they wanted it.
Lightning arrestor is a spark-gap device, and can be installed anywhere. What is important, is that the wire is thick enough to withstand the lightning bolt and conduct the energy away from the building.
But it can get overloaded, and no longer works.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
what exactly is a ‘surge’ protector?
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
Once the voltage goes over 0.0650 volts, then this fact can be used to amplify the difference, and turn the circuit breaker off , furthur down the line. Essentially that is what a RCD/GFCI does, it compares the incoming current, to the outgoing current, and if the difference between the two currents is over 5mA, then it trips the circuit breaker.
There is no harm in having the surge suppressor along with the fuse in the circuit. The fuse will not open up until the current melts the link. This will take time, and in the interim, that jolt will get transmitted into the power supplies.
Upvotes:
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
A fuse is a non-resetable over current circuit protector.
but this device (an Inductor) … impedes the rapid changes in the current.
The third is lightning and “how it gets conducted into a home.”
This is where this question deviates from being a 'generic' question, and becomes more specific.

There are two important concepts here.
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
In schematic diagrams this is the symbol for a fuse:
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
