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?

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

But… the neutral is now “floating” because of the 1 ohm resistance.
There are two important concepts here.

so, what happens?
“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”
A circuit breaker is similar, but is resettable.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
Edit 2024–10.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
In schematic diagrams this is the symbol for a fuse:
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.

This is where the MOV conducts again, and dissipated the energy.
A fuse is a non-resetable over current circuit protector.
These are simplified answers to the original question, and does not change anything I wrote above.
the problem then depends on "how fast does the fuse operate?".

But it can get overloaded, and no longer works.

The other is “what does a “fuse” do?”
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).

Here is a simplified AC power diagram.
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

(Dc diagram shown, AC is similar).
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.

What is lightning?
Now when you have a certain ac resistance, then a current flows in a loop.
There are three different concepts here that are getting confused.
This device then solves the entire problem.

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.
What does it mean when someone is pretending to be me?
a photo is worth a thousand words.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
He then describes Rainy Season and Lightning.

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
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 where this question deviates from being a 'generic' question, and becomes more specific.
The MOV will conduct when the voltage exceeds 50% of line voltage.
At one ohm, the resistor has a maximum of 1 watt power.

What does a fuse do?
For this case there are devices called Metal oxide varistors (MOV).

At least they know the answer if they wanted it.

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
An AC voltage/ current source, and an ac inductive load.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
It also is a device that limits the change in current flow.
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.

but this device (an Inductor) … impedes the rapid changes in the current.
I post the exact comment here.
The third is lightning and “how it gets conducted into a home.”
This one hit behind the barn.
“ 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'
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
but I think this circuit , shows a few more pieces.
These devices are installed between the “hot” and “neutral” and protective ground.
First Sentence:
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).
what exactly is a ‘surge’ protector?
The bolt then partially travels down the line to your home.
Upvotes:
He then describes the function of a fuse.
It seems Mohan does not understand the difference between a comment and an Answer.
He then asserts :
