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?

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

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
What is lightning?
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.
The other is “what does a “fuse” do?”

He then asserts :
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.

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.
“ 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”
At least they know the answer if they wanted it.
It seems Mohan does not understand the difference between a comment and an Answer.

This is 'the assistant's answer'
One is “what exactly is in a ‘surge protector’ ? ”
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
the problem then depends on "how fast does the fuse operate?".
He then describes the function of a fuse.

The MOV will conduct when the voltage exceeds 50% of line voltage.

But… the neutral is now “floating” because of the 1 ohm resistance.
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.
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.
Here is a simplified AC power diagram.
These devices are installed between the “hot” and “neutral” and protective ground.
This device then solves the entire problem.
So, the voltage could go up to 500 volts, and the fuse will not open up.
There are three different concepts here that are getting confused.

A fuse is a non-resetable over current circuit protector.

Because the load is inductive, the current lags the voltage.(by a bit).
For this case there are devices called Metal oxide varistors (MOV).
Edit 2024–10.
There are two important concepts here.
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.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
It also is a device that limits the change in current flow.
(Dc diagram shown, AC is similar).
These are simplified answers to the original question, and does not change anything I wrote above.
In schematic diagrams this is the symbol for a fuse:
Upvotes:
The third is lightning and “how it gets conducted into a home.”
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 this device (an Inductor) … impedes the rapid changes in the current.
Now when you have a certain ac resistance, then a current flows in a loop.
What does a fuse do?
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
A circuit breaker is similar, but is resettable.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

what exactly is a ‘surge’ protector?
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.
2024–10–11 [Victor Olarewsju Victor Olarewaju ]
This is where this question deviates from being a 'generic' question, and becomes more specific.

Can the fuse protect the electronic devices from lightning instead of a surge protector.
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
