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.

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

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.

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

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

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

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

A circuit breaker is similar, but is resettable.

Why does Boko Haram attack its own Muslims?

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

There are two important concepts here.

There are three different concepts here that are getting confused.

Ive been pretending to be okay and acting as normal as possible, but Im actually completely heartbroken after a recent breakup. Its painful and really affecting me, to the point where I cant concentrate at work, Ive lost my appetite, I cant sleep, and It feels as if my whole world has been turned upside down. I loved him so much. He said so many cruel things to me and it made me realize he must not have loved me the way I loved him, or he wouldnt have said such horrible things. How do I handle the heartbreak and why cant I accept that he didnt love me and just forget about him?

This device then solves the entire problem.

In schematic diagrams this is the symbol for a fuse:

Feather-legged lace weaver spider kills prey by covering it with toxic silk - Phys.org

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

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

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

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

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

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.

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

If babies could write, what questions would they ask on Quora?

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

This is 'the assistant's answer'

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

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

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

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

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

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.

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.

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

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

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

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.

what exactly is a ‘surge’ protector?

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

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

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

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

This one hit behind the barn.

(Dc diagram shown, AC is similar).

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

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.

But it can get overloaded, and no longer works.

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

so, what happens?

a photo is worth a thousand words.

The other is “what does a “fuse” do?”

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

What is lightning?

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.

He then describes the function of a fuse.

First Sentence:

“ 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”

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

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

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

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.
