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?

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

He then describes the function of a fuse.

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

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

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

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

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

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

There are three different concepts here that are getting confused.

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

In schematic diagrams this is the symbol for a fuse:

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.

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

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

But it can get overloaded, and no longer works.

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

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

(Dc diagram shown, AC is similar).

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

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

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

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

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.

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

First Sentence:

Were you ever in love with your teacher?

“ 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”

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

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

The other is “what does a “fuse” do?”

There are two important concepts here.

At least they know the answer if they wanted it.

What if Homelander turned out to be a good guy instead of an evil milk drinking manchild? Nobody seems to touch on this much.

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

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

what exactly is a ‘surge’ protector?

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

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

What does a fuse do?

I post the exact comment here.

What is lightning?

so, what happens?

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

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

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

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

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

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.

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

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

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

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 circuit breaker is similar, but is resettable.

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

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

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.

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

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

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

Edit 2024–10.

Here is a simplified AC power diagram.

This device then solves the entire problem.

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

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

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.

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