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?

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
He then asserts :
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

the problem then depends on "how fast does the fuse operate?".

But it can get overloaded, and no longer works.

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

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
At least they know the answer if they wanted it.

It seems Mohan does not understand the difference between a comment and an Answer.
For this case there are devices called Metal oxide varistors (MOV).
But… the neutral is now “floating” because of the 1 ohm resistance.
A circuit breaker is similar, but is resettable.
so, what happens?

The other is “what does a “fuse” do?”
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.
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?".
He then describes the function of a fuse.
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 combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
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.
So, the voltage could go up to 500 volts, and the fuse will not open up.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”

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.
“ 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”
He then describes Rainy Season and Lightning.

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.
Because the load is inductive, the current lags the voltage.(by a bit).
This is where this question deviates from being a 'generic' question, and becomes more specific.
What makes you feel guilty the most?
It also is a device that limits the change in current flow.
There are three different concepts here that are getting confused.

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

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

These devices are installed between the “hot” and “neutral” and protective ground.

What does a fuse do?
Now when you have a certain ac resistance, then a current flows in a loop.

The bolt then partially travels down the line to your home.
Can the fuse protect the electronic devices from lightning instead of a surge protector.

This device then solves the entire problem.
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.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
but I think this circuit , shows a few more pieces.
At one ohm, the resistor has a maximum of 1 watt power.
This is where the MOV conducts again, and dissipated the energy.
There are two important concepts here.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
I post the exact comment here.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
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.”

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
A fuse is a non-resetable over current circuit protector.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
