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 are two important concepts here.

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

Can you explain the meaning of "mint condition" in relation to antiques or collectibles?

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

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.

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

I post the exact comment here.

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.

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.

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

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

what exactly is a ‘surge’ protector?

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

He then asserts :

Does Donald Trump have low self-esteem?

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

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

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

Have you been arrested or investigated?

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.

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

What is the best case of “You just picked a fight with the wrong person” that you've witnessed?

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

The other is “what does a “fuse” do?”

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

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

At least they know the answer if they wanted it.

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

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

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

Edit 2024–10.

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

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 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.

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

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

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

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

This device then solves the entire problem.

so, what happens?

A circuit breaker is similar, but is resettable.

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

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.

a photo is worth a thousand words.

He then describes the function of a fuse.

“ 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”

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

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

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.

He then describes Rainy Season and Lightning.

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’ ? ”

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

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

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

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

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

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

What does a fuse do?

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

There are three different concepts here that are getting confused.
