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?

This is where the MOV conducts again, and dissipated the energy.
The MOV will conduct when the voltage exceeds 50% of line voltage.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
This is where this question deviates from being a 'generic' question, and becomes more specific.

There are three different concepts here that are getting confused.
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.

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.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

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.
The third is lightning and “how it gets conducted into a home.”
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
An AC voltage/ current source, and an ac inductive load.
For this case there are devices called Metal oxide varistors (MOV).

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’ ? ”
A fuse is a non-resetable over current circuit protector.
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.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

A circuit breaker is similar, but is resettable.

I post the exact comment here.
but I think this circuit , shows a few more pieces.
At least they know the answer if they wanted it.
the problem then depends on "how fast does the fuse operate?".
First Sentence:
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
Now when you have a certain ac resistance, then a current flows in a loop.
In schematic diagrams this is the symbol for a fuse:
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.
There are two important concepts here.
These devices are installed between the “hot” and “neutral” and protective ground.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
He then describes the function of a fuse.
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.
Because the load is inductive, the current lags the voltage.(by a bit).
but this device (an Inductor) … impedes the rapid changes in the current.

It also is a device that limits the change in current flow.
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
So, the voltage could go up to 500 volts, and the fuse will not open up.

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
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.
