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?

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 combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

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

There are three different concepts here that are getting confused.

One is “what exactly is in a ‘surge protector’ ? ”

so, what happens?

For this case there are devices called Metal oxide varistors (MOV).

What is something you want to "get off your chest"?

There are two important concepts here.

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.

At least they know the answer if they wanted it.

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.

So, the voltage could go up to 500 volts, and the fuse will not open up.

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.

I post the exact comment here.

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

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

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.

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

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.

An AC voltage/ current source, and an ac inductive load.

what exactly is a ‘surge’ protector?

One

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.

(Dc diagram shown, AC is similar).

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 it can get overloaded, and no longer works.

What is lightning?

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

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

But… the neutral is now “floating” because of the 1 ohm resistance.

He then describes Rainy Season and Lightning.

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

Now when you have a certain ac resistance, then a current flows in a loop.

He then asserts :

Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

Edit 2024–10.

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

This is where the MOV conducts again, and dissipated the energy.

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

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

He then describes the function of a fuse.

The bolt then partially travels down the line to your home.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

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

This is 'the assistant's answer'

The third is lightning and “how it gets conducted into a home.”

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.

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.

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

Because the load is inductive, the current lags the voltage.(by a bit).
