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?

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

This is where this question deviates from being a 'generic' question, and becomes more specific.
Why do our deceased do not protect us from other bad spirits?
In schematic diagrams this is the symbol for a fuse:
(Dc diagram shown, AC is similar).

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

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

There are three different concepts here that are getting confused.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
What does a fuse do?
What song are you listening to right now? What does it mean to you?
The bolt then partially travels down the line to your home.
Because the load is inductive, the current lags the voltage.(by a bit).
This is where the MOV conducts again, and dissipated the energy.
“ 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 is 'the assistant's answer'
He then describes Rainy Season and Lightning.

This device then solves the entire problem.
An AC voltage/ current source, and an ac inductive load.

But… the neutral is now “floating” because of the 1 ohm resistance.

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.
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
It also is a device that limits the change in current flow.

The third is lightning and “how it gets conducted into a home.”
One is “what exactly is in a ‘surge protector’ ? ”
Who are the archers in Genesis 49:23?
He then asserts :
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
He then describes the function of a fuse.
A fuse is a non-resetable over current circuit protector.

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
This one hit behind the barn.
what exactly is a ‘surge’ 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.

These devices are installed between the “hot” and “neutral” and protective ground.
The MOV will conduct when the voltage exceeds 50% of line voltage.
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.
How did you as a human being change while growing up?
but I think this circuit , shows a few more pieces.
but this device (an Inductor) … impedes the rapid changes in the current.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
It seems Mohan does not understand the difference between a comment and an Answer.
A circuit breaker is similar, but is resettable.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

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.
a photo is worth a thousand words.
The other is “what does a “fuse” do?”
At one ohm, the resistor has a maximum of 1 watt power.
For this case there are devices called Metal oxide varistors (MOV).
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
Edit 2024–10.
so, what happens?
Can the fuse protect the electronic devices from lightning instead of a surge protector.
Now when you have a certain ac resistance, then a current flows in a loop.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
There are two important concepts here.
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.
So, the voltage could go up to 500 volts, and the fuse will not open up.
One
the problem then depends on "how fast does the fuse operate?".
What is lightning?

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.

These are simplified answers to the original question, and does not change anything I wrote above.

I post the exact comment here.
[old diagram got deleted by accident]
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.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
At least they know the answer if they wanted it.
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.
