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?

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

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.

This is an electronic circuit designed to clamp voltages so that the Voltage Potential that appears at the outlet is never going to exceed the nominal value.
The MOV will conduct when the voltage exceeds 50% of line voltage.
But it can get overloaded, and no longer works.

Can the fuse protect the electronic devices from lightning instead of a surge protector.

What does a fuse do?
Edit 2024–10.
A fuse is a non-resetable over current circuit protector.

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.
So, the voltage could go up to 500 volts, and the fuse will not open up.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

It also is a device that limits the change in current flow.
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
“ 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”
This device then solves the entire problem.
the problem then depends on "how fast does the fuse operate?".
These devices are installed between the “hot” and “neutral” and protective ground.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
One is “what exactly is in a ‘surge protector’ ? ”

This is where this question deviates from being a 'generic' question, and becomes more specific.
This is the picture of an electronic coil of wire wound around a core of magnetic material.
A circuit breaker is similar, but is resettable.
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.
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.
The bolt then partially travels down the line to your home.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
He then describes the function of a fuse.
What is lightning?
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
In schematic diagrams this is the symbol for a fuse:
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
This is where the MOV conducts again, and dissipated the energy.

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.
so, what happens?
At one ohm, the resistor has a maximum of 1 watt power.
Now when you have a certain ac resistance, then a current flows in a loop.

It seems Mohan does not understand the difference between a comment and an Answer.
I post the exact comment here.
This is a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.
But… the neutral is now “floating” because of the 1 ohm resistance.
but this device (an Inductor) … impedes the rapid changes in the current.
but I think this circuit , shows a few more pieces.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
For this case there are devices called Metal oxide varistors (MOV).
An AC voltage/ current source, and an ac inductive load.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
2024–10–11 [Bobby Sanchez Bobby Sanchez ].
Because the load is inductive, the current lags the voltage.(by a bit).
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
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.

The third is lightning and “how it gets conducted into a home.”
