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?

He then describes Rainy Season and Lightning.
what exactly is a ‘surge’ protector?
This is where this question deviates from being a 'generic' question, and becomes more specific.

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

So, the voltage could go up to 500 volts, and the fuse will not open up.
First Sentence:
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
What is lightning?

Now when you have a certain ac resistance, then a current flows in a loop.
For this case there are devices called Metal oxide varistors (MOV).

He then describes the function of a fuse.
This one hit behind the barn.
At one ohm, the resistor has a maximum of 1 watt power.

A fuse is a non-resetable over current circuit protector.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

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

There are two important concepts here.
A circuit breaker is similar, but is resettable.
Here is a simplified AC power diagram.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

The bolt then partially travels down the line to your home.
but this device (an Inductor) … impedes the rapid changes in the current.

a photo is worth a thousand words.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
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.
the problem then depends on "how fast does the fuse operate?".
The other is “what does a “fuse” do?”
This is where the MOV conducts again, and dissipated the energy.
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.
In schematic diagrams this is the symbol for a fuse:
But… the neutral is now “floating” because of the 1 ohm resistance.
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.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
I post the exact comment here.
But it can get overloaded, and no longer works.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

These devices are installed between the “hot” and “neutral” and protective ground.
One is “what exactly is in a ‘surge protector’ ? ”
What does a fuse do?
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.
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 the nominal power is 4,000 watts then the current at 230volts is 16 amps.
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.
This device then solves the entire problem.
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
An AC voltage/ current source, and an ac inductive load.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
There are three different concepts here that are getting confused.
