I think that's the most simple version of short circuit protection

This is the 3am content i was looking for

Unlike other circuits in this series which are just entertaining peculiar or curious, this is actually useful! And it actually makes sense to build it "in plein air" instead than on a pcb.

Do NOT push the button if the circuit still shorted!

[ytteman]

Only use this if the power supply has some current limit implemented. Don't power this circuit directly from a battery.

[electronicdude]

I have implemented this method in my home made power supply and works over a wide range of voltage (3v to 18v)

Risk of blowing the fuse while shorting each time. Very simple and Good project for a 10th class physics student

[elvhansegotier]

Thank you so much for this idea.
This was helpful to my 12v power supply ❤❤

precisa ser uma fonte com limitação de corrente, por exemplo usando um resistor de baixo valor para proteger os contatos do relé.

[vencdee]

There should be a small power resistor before the relay (e.g. 0.5Ohm) to assure reasonable voltage drop.
Secondly, it starts working once the reset button is pushed.
I would consider using resettable thermal fuse chosen for the amps of the motor instead if the latching indicator (LEDs) is not needed.

[SuburbanDon]

It looks like a latching relay and shorting it just kills power to the relay. Looks legit.

[peraperic]

Bad design. Accidentally pressing ‘reset’ button while still in ‘short’ state (thinking it would remove ‘short’) will blow your fuse, which cancels the point of the circuit.
Also, don’t use this on anything high-voltage.
Shorting relay’s isolated contacts to live ones, even for a short time, denies the purpose of relay: to keep those contacts isolated at all time.
Best purpose of this is to show how to not design protection circuits.

[AntonZharov]

Сделал восстанааливающийся предохрагитель! Браво! Пойду велик изобретать!

[zokmjvk]

Хорошая простая схема, вот только не долговечная, т.к. на контактах реле будет дуга через замыкание.

[Orthodoctus]

I'm not an electrical engineer, but from looking at this circuit, there doesn't seem to be any latching mechanism, and what you see here is the protection circuit of the power supply he is using. Don't try this with a 12V car battery!

Nossa isso foi realmente incrível sério mesmo preciso fazer esse projeto um abraço do brazil

[hana-audio]

when you dont search for it & just pop out in short..
"Hey i need it"

[YBK]

В момент касания белым проводом синего он замыкает источник питания. На видео у него скорей всего подключено от бп с защитой по току. Ну а если это подключить от акума то будет мальнькая сварка и обгорят контакты в рэле.😊. И тогда не понятен вообще смысл этого изобретения.

[RandomRobloxuser-mxxi]

What happens if I put 240 V on it??

A: it blows up (like)
B: melts the hell out of the wires and burns down the table (comment)
C: any other thoughts (comment)

muito bom, já montei esses circuito, ele suporta uma boa corrente, mas se houver curto mesmo em uma corrente mais baixa, ele desarma.
