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?

A circuit breaker is similar, but is resettable.
This device then solves the entire problem.
What does a fuse do?
What is your review of the Redmi 9A? Is it worth buying?
An AC voltage/ current source, and an ac inductive load.
The other is “what does a “fuse” do?”
He then describes the function of a fuse.

but I think this circuit , shows a few more pieces.

Bank of Japan leaves interest rate unadjusted at 0.5% as expected - FXStreet
But… the neutral is now “floating” because of the 1 ohm resistance.
Here is a simplified AC power diagram.
So, the voltage could go up to 500 volts, and the fuse will not open up.
Was Jimmy Carter a good President of the United States?
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.

For this case there are devices called Metal oxide varistors (MOV).
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”
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

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.
If babies could write, what questions would they ask on Quora?
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
This one hit behind the barn.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
He then describes Rainy Season and Lightning.

He then asserts :

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

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.
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.
Why do very skinny girls get more male attention if it is true that men like curves?
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
One is “what exactly is in a ‘surge protector’ ? ”
In schematic diagrams this is the symbol for a fuse:

There are two important concepts here.
the problem then depends on "how fast does the fuse operate?".
It seems Mohan does not understand the difference between a comment and an Answer.

but this device (an Inductor) … impedes the rapid changes in the current.
This is where the MOV conducts again, and dissipated the energy.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
I post the exact comment here.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
This is where this question deviates from being a 'generic' question, and becomes more specific.
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
The third is lightning and “how it gets conducted into a home.”

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
At least they know the answer if they wanted it.
so, what happens?
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
Now when you have a certain ac resistance, then a current flows in a loop.
a photo is worth a thousand words.
There are three different concepts here that are getting confused.
These devices are installed between the “hot” and “neutral” and protective ground.
A fuse is a non-resetable over current circuit protector.
At one ohm, the resistor has a maximum of 1 watt power.
(Dc diagram shown, AC is similar).

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 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.

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?
what exactly is a ‘surge’ protector?
What is lightning?
The MOV will conduct when the voltage exceeds 50% of line voltage.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
The bolt then partially travels down the line to your home.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
2024–10–16 [ OO OLAOYE OYEBODE ]
Because the load is inductive, the current lags the voltage.(by a bit).
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
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.
These are simplified answers to the original question, and does not change anything I wrote above.
