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?

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

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.

Why do men cheat on their wives with someone extremely unattractive?

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

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.

Why did my ex-narcissist move so fast with his new supply marriage engagement moving in, etc.?

but I think this circuit , shows a few more pieces.

It seems Mohan does not understand the difference between a comment and an Answer.

He then asserts :

Why do many women wear sleeveless shirts, more so than men?

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

Can the fuse protect the electronic devices from lightning instead of a surge protector.

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.

Why do people keep complaining about how some people copy and paste the question before answering it? To me, it's very disturbing and makes me want to block and mute them as annoying whiners.

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

so, what happens?

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

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

Why is my coworker suddenly being so mean towards then being nice like nothing happened? She is nice with everyone but me.

The other is “what does a “fuse” do?”

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

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.

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

If everyone in Russia dropped into holes in the ground only never to return, would that be good for NATO and international peacekeepers? Can we convince Russians to be less diabolical, so they coexist? Does Putin stink like doo doo in the commode?

There are three different concepts here that are getting confused.

Do you think Trump is a bad a$$? Why or why not?

This is where this question deviates from being a 'generic' question, and becomes more specific.

Edit 2024–10.

I post the exact comment here.

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

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

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

A circuit breaker is similar, but is resettable.

Why is Prince Harry being fired by BetterUp CEO Alexi Robichaux, and what role did Marc Benioff’s decision to pull sponsorship play in this?

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

This one hit behind the barn.

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

(Dc diagram shown, AC is similar).

Here is a simplified AC power diagram.

“ A fuse is a device which protects the (circuit) against overload and short circuit.”

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.

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

This is 'the assistant's answer'

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

First Sentence:

what exactly is a ‘surge’ protector?

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).

the problem then depends on "how fast does the fuse operate?".

At least they know the answer if they wanted it.

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

These are simplified answers to the original question, and does not change anything I wrote above.

But it can get overloaded, and no longer works.

(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

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

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

“ 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”

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.

At one ohm, the resistor has a maximum of 1 watt power.

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

In schematic diagrams this is the symbol for a fuse:

He then describes the function of a fuse.

[old diagram got deleted by accident]

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

One

but this device (an Inductor) … impedes the rapid changes in the current.

What is lightning?

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

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.

This device then solves the entire problem.

What does a fuse do?

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

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

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.

There are two important concepts here.

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

This is the picture of an electronic coil of wire wound around a core of magnetic material.

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

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.
