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, what happens?

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

(Dc diagram shown, AC is similar).

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.

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

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

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

The other is “what does a “fuse” do?”

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

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

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

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

A circuit breaker is similar, but is resettable.

This device then solves the entire problem.

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

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.

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.

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

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

Why does my private parts itch so much during certain periods?

a photo is worth a thousand words.

In schematic diagrams this is the symbol for a fuse:

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.

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

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

Do you agree with Michael Moore that Donald Trump is "toast" in a political comeback?

He then asserts :

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

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

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

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

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

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

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

He then describes the function of a fuse.

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

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

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

At least they know the answer if they wanted it.

I post the exact comment here.

There are two important concepts here.

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

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

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%).

what exactly is a ‘surge’ protector?

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.

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.

But it can get overloaded, and no longer works.

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

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”

What does a fuse do?

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

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

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.

This is 'the assistant's answer'

Here is a simplified AC power diagram.

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

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

What is lightning?

There are three different concepts here that are getting confused.

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

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

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

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

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.
