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?

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.
He then describes the function of a fuse.

At least they know the answer if they wanted it.

It also is a device that limits the change in current flow.

but I think this circuit , shows a few more pieces.
Why do narcissist move on so easily?
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
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.
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.

Now when you have a certain ac resistance, then a current flows in a loop.
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

The MOV will conduct when the voltage exceeds 50% of line voltage.
These devices are installed between the “hot” and “neutral” and protective ground.
There are two important concepts here.
But it can get overloaded, and no longer works.
This device then solves the entire problem.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
The bolt then partially travels down the line to your home.

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
This is where the MOV conducts again, and dissipated the energy.

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
what exactly is a ‘surge’ protector?
the problem then depends on "how fast does the fuse operate?".
What is lightning?
There are three different concepts here that are getting confused.
What does a fuse do?
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.
It seems Mohan does not understand the difference between a comment and an Answer.
Edit 2024–10.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
This is where this question deviates from being a 'generic' question, and becomes more specific.
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.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
He then asserts :
But… the neutral is now “floating” because of the 1 ohm resistance.

He then describes Rainy Season and Lightning.
I post the exact comment here.
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.”
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
Upvotes:
The other is “what does a “fuse” do?”
Because the load is inductive, the current lags the voltage.(by a bit).
Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

So, the voltage could go up to 500 volts, and the fuse will not open up.
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
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, what happens?

These are simplified answers to the original question, and does not change anything I wrote above.
At one ohm, the resistor has a maximum of 1 watt power.
