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?

These devices are installed between the “hot” and “neutral” and protective ground.
What is lightning?
This is where this question deviates from being a 'generic' question, and becomes more specific.
The bolt then partially travels down the line to your home.
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
I post the exact comment here.
What are 10 interesting facts about you?
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
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 MOV will conduct when the voltage exceeds 50% of line voltage.

It seems Mohan does not understand the difference between a comment and an Answer.
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.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
Now when you have a certain ac resistance, then a current flows in a loop.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
He then asserts :

These are simplified answers to the original question, and does not change anything I wrote above.
a photo is worth a thousand words.
But… the neutral is now “floating” because of the 1 ohm resistance.

what exactly is a ‘surge’ protector?
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

The other is “what does a “fuse” do?”

the problem then depends on "how fast does the fuse operate?".
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.

At one ohm, the resistor has a maximum of 1 watt power.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
So, the voltage could go up to 500 volts, and the fuse will not open up.
A circuit breaker is similar, but is resettable.

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).

but this device (an Inductor) … impedes the rapid changes in the current.
A fuse is a non-resetable over current circuit protector.

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

so, what happens?
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.
An AC voltage/ current source, and an ac inductive load.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
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.
There are three different concepts here that are getting confused.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
This is the picture of an electronic coil of wire wound around a core of magnetic material.
(Dc diagram shown, AC is similar).

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
There are two important concepts here.

What does a fuse do?
It also is a device that limits the change in current flow.
“ 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”
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

At least they know the answer if they wanted it.
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.
This is where the MOV conducts again, and dissipated the energy.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

In schematic diagrams this is the symbol for a fuse:
This is 'the assistant's answer'
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
For this case there are devices called Metal oxide varistors (MOV).
Here is a simplified AC power diagram.
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, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

He then describes the function of a fuse.
This device then solves the entire problem.
But it can get overloaded, and no longer works.
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.
