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?

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

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

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

So, the voltage could go up to 500 volts, and the fuse will not open up.
OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
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.
I post the exact comment here.

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".
There are three different concepts here that are getting confused.
He then describes the function of a fuse.

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
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.
The MOV will conduct when the voltage exceeds 50% of line voltage.

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.
In schematic diagrams this is the symbol for a fuse:
For this case there are devices called Metal oxide varistors (MOV).

what exactly is a ‘surge’ protector?

Can the fuse protect the electronic devices from lightning instead of a surge protector.
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
(Dc diagram shown, AC is similar).
Because the load is inductive, the current lags the voltage.(by a bit).
so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
He then describes Rainy Season and Lightning.
A fuse is a non-resetable over current circuit protector.
There are two important concepts here.
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.
This is where this question deviates from being a 'generic' question, and becomes more specific.
Upvotes:
But… the neutral is now “floating” because of the 1 ohm resistance.
(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.
These devices are installed between the “hot” and “neutral” and protective ground.

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.

Here is a simplified AC power diagram.
This is where the MOV conducts again, and dissipated the energy.
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

These are simplified answers to the original question, and does not change anything I wrote above.
So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.
At one ohm, the resistor has a maximum of 1 watt power.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
Now when you have a certain ac resistance, then a current flows in a loop.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
But it can get overloaded, and no longer works.

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
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 a fuse do?
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.
but this device (an Inductor) … impedes the rapid changes in the current.
