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?

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

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

The other is “what does a “fuse” do?”

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.

“ 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.

There are three different concepts here that are getting confused.

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

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

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.

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

Here is a simplified AC power diagram.

What is lightning?

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

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

What does a fuse do?

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

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

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.

(Dc diagram shown, AC is similar).

a photo is worth a thousand words.

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.

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.

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

This one hit behind the barn.

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.

[old diagram got deleted by accident]

“ 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”

This device then solves the entire problem.

2024–10–10[John johnson John Johnson ]

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

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

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

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 a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.

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

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

But it can get overloaded, and no longer works.

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

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

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

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

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

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.

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

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

A circuit breaker is similar, but is resettable.

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.
