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?

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

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.

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

(Dc diagram shown, AC is similar).

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

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

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

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

If Donald Trump is so evil and Joe Biden is so good why is Trump the one selflessly providing Bibles for the needy while Biden doesn't? Why doesn't Biden care for America's spiritually needy people as much as Trump?

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

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.

California schools are very liberal. Do you think California schools are teaching students to hate Republican views (views on: God, guns, prayer, secure borders, etc.)?

This device then solves the entire problem.

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

But it can get overloaded, and no longer works.

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

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

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

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

At least they know the answer if they wanted it.

What is lightning?

He then asserts :

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

so, what happens?

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

He then describes the function of a fuse.

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

I post the exact comment here.

The other is “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.

What was the craziest place that you had sex with someone in public?

There are two important concepts here.

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.

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

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

One

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.

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

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

what exactly is a ‘surge’ protector?

This is 'the assistant's answer'

a photo is worth a thousand words.

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

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

(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.

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

Here is a simplified AC power diagram.

He then describes Rainy Season and Lightning.

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

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

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

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 the MOV conducts again, and dissipated the energy.

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

This one hit behind the barn.

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

“ 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”

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

What does a fuse do?

There are three different concepts here that are getting confused.

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

Edit 2024–10.

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.
