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?

what exactly is a ‘surge’ protector?

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

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

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

He then asserts :

How do we greet in German, French, Spanish, and Italian?

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

This one hit behind the barn.

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

He then describes Rainy Season and Lightning.

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

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

It’s been over a month since I stopped taking sertraline but why do I still feel side effects like brain zaps and anxiety mood changes? The root cause of anxiety it’s your thinking and I perfectly master that better than before so it’s hard lately.

There are two important concepts here.

I post the exact comment here.

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

Why cant I sleep on my side after getting my covid vaccine? I just got the shot and I’ve been overstimulated from not being able to sleep, my arm is very sore and it hurts so much to move and I just want to sleep but it hurts if I lay on either side

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

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.

How can I fall asleep fast at night?

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

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

What is the best way to keep my vagina clean and fresh?

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

He then describes the function of a fuse.

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

Why do females hate MGTOW so much?

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.

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

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

Why do I smell bad even though I have good hygiene?

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

A circuit breaker is similar, but is resettable.

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

One is “what exactly is in 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.

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

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

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

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

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

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

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

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

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

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

But it can get overloaded, and no longer works.

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

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

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

At least they know the answer if they wanted it.

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

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.

This is 'the assistant's answer'

[image of Common-mode choke]

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

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

In schematic diagrams this is the symbol for a fuse:

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

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.

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.

This device then solves the entire problem.

Edit 2024–10.

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

Here is a simplified AC power diagram.

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

“ 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”

The other is “what does a “fuse” do?”

[old diagram got deleted by accident]

What does a fuse do?

Barnstars:

so, what happens?

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

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.

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