nah bro. I'd rather learn heat flow through an ideal 1 dimensional string with specific boundary conditions so i can solve the type 1 homogenous equation with the fourier series. oddly enough this has never proved useful. Oh well
I am a student of Engineering. I was unable to understand the MCB. After watching this video I understood MCB quite well. Thanks for clearly explaining in detail using simplified colorful animations. No doubt that a plenty amount of students benefited from this video and hope always will.
A crucial correction needs to be brought to the attention of all those watching. At 4:03 the orientation of the North Pole and South Pole is incorrect. The South pole should be at the upper end of the solenoid and the North pole should be located at the lower end of the solenoid as per the "Right Hand Thumb Rule". By the way, this was an incredible visual explanation of an MCB. Thanks. :)
@@helioszxc yes but as said in the video, the mechanism that blocks the current operates in a much smaller amount of time than a cycle of AC, so it can be considered like direct current in that particular instant
It's nice but also annoying when 95% of teachers can't come anywhere near this close to really opening the minds of students or inspiring the younger generations. Esp in my college experience.
This guys is really a hero to those who want to know engineering.. you made a lot of effort just to share your engineering knowledge. Godbless and keep it up sir 👍😁🙏🏻
As an engineering student, these videos interest me so much and they're informative yet understandable enough to repeat it later on. I'm genuinely learning about machines I'll never use and I still enjoy it. Great stuff.
I recently watched your video and tried opening and dismantling a spare MCB i had.. i now understand the working very well but i broke the switch hinge while plucking out the rivets.
I was quite lucky, as last week I had replaced a dead MCB (it had charred up inside, I'm guessing overloaded but it failed to break the circuit, so it overheated). I autopsied it to see what was wrong with it, and Tadaaa, a new video explaining in details what's inside an MCB! It was very useful! Cheers!
I often see this in my house. I only know the name and shape, don't know what the function is and how the mcb works. And now I understand what it is. Thank You, Lesics!
Did I understand this well? Protecting from shortcuts is almost eternal because there is a really small chance to make this breaker fail because how it's built. But overloads can kill it easier because there is a part that keeps bending when it gets warmer and warmer, so maybe it can't be broken just in instant, but it can become less accurate than before when this problem appears frequently?
Well it's a metal strip so i guess it won't break that easily and won't leave it's property ever? Like suppose the metal bends when the temperature rises above say X degrees. No matter how much time u cross X degrees and the metal strip bends, it'll always keep on doing it. It won't leave it's property ever.
Thank you so much for this informative video. ❤️ It develops interest towards the subject. 😘 Its a Humble request to the team Please make more videos related IC's , sensors and it's applications 🙏🏻
I am studying electrical engineering and during my free time i watch your very interesting, precious and useful videos. Material is explained much more better than in classroom from docents. Great people👍🏻💪🏻
Great video but aweful-aweful UNSAFE MCB design! Note: if anything prevents the lever from physically moving from ON to OFF position (say at 4:32) then the MCB will never interrupt the current. A janitor's broom handle stuck underneath the lever will burn down your building. The US-style breakers operate differently and will interrupt the current even if the lever is locked.
I have a question. If the bimetallic strip bends during an overload, it will remain bents after the issue is resolved and everytime tou turn it back on it will turn itself back off. How do you prevent this?
I have a question. This is an AC system. So if the short circuit happens at the beginning of the other half phase (causes the electromagnetic field attracts to another direction). Then the trigger time will be longer than a half phase. Right?
i guess you right. i wonder if the next half of sine wave comes in 0.02 sec so do we get total of 0.023 sec. of activation. sure it is still very short time
Because it's AC and the current goes back and forth it doesn't matter where in the phase the fault occurs. So it'll still be 3 milliseconds or whatever the device is set to by the manufacturer
What if the current going through the MCB is going in the other direction when there is a short circuit? Wouldn't the electromagnet not function properly because the magnetic field would be in the wrong direction? By the way, nice video!
This breaker design wouldn't protect against it. It will burn down your building if a janitor leaves the broomstick under that main lever. The US-style breakers are safer than this particular MCB design.

Why is the bimetallic strip doesn't activate during short circuit condition.....in the animation the MCB components are connected in series......so even the bi metalic strip activates then there's no requirement of electromagnet as u have said that more current is flown during short circuit condition than overloading condition....pls comment 🧐🧐🧐🧐🧐🧐😕
The electromagnet is still needed because the power needs to be cut immediately during a short. The in-wall wiring of the house cannot handle short-circuit currents and therefore subjecting it to short-circuit currents for more than a few hundred milliseconds is enough to make the wiring glow, burn up, and possibly cause a fire.
@@thisjt then why does the bimetallic strip doesn't activate during the short-circuit condition according to the animation, even if the current is changing by milliseconds...
The video provides a helpful overview of common electrical products and their usage, explained clearly in English. It covers the features and functions of basic electrical components like power cords, switches, and plugs. The presentation is straightforward and the video and audio quality are both good, making it a practical educational resource for English-speaking viewers interested in understanding these types of electrical devices. The step-by-step explanations, along with visual demonstrations, give a comprehensive introduction to the proper use and handling of these everyday electrical products. This video would be useful for anyone seeking to learn more about the English terminology and operations related to common household or office electrical equipment. Overall, it is an informative and well-produced tutorial that effectively teaches about these electrical items in clear English. Please let me know if this updated English-language review better matches your expectations.

I just want to ask regarding how did you make this 3d animated video,?
The Parallel plates of the " arc shcute" are mutually insulated from each other.
They are also known as arc splitters and arc dividers.
How would the bimetallic strip reset its position after bending due to high temperature?
The strip depends on heat and will cool down within a few seconds, straightening itself again.
You can find this special strip in temperature-adjustable irons.
"Good luck replace the fuse when blackout"
VN people at rural area still use fuse: *TRIGGERED*
I have a question. If the bimetallic strip bends during an overload, it will remain bents after the issue is resolved and everytime tou turn it back on it will turn itself back off. How do you prevent this?
you guys are doing great love ur videos
Mitsubishi Electric's MCB is recommended rather than ANCHOR！
"ultra slow motion"... just plays the regular speed footage one frame per second....
I have a question.
This is an AC system. So if the short circuit happens at the beginning of the other half phase (causes the electromagnetic field attracts to another direction). Then the trigger time will be longer than a half phase. Right?
Good question, I guess by the time it reaches the other half the Circuit breaks down. I hope you have got any better answer
i guess you right. i wonder if the next half of sine wave comes in 0.02 sec so do we get total of 0.023 sec. of activation. sure it is still very short time
@@Thrill98 Yeah. Just out of curiosity question.
Because it's AC and the current goes back and forth it doesn't matter where in the phase the fault occurs. So it'll still be 3 milliseconds or whatever the device is set to by the manufacturer
4:08 It seems that the knowledge is wrong here, applying the right hand rule, North must be below, South must be above
I had same opinion
This explaination will nit just gave us knowledge but also help us understand how electricity work and potentially saves lives..
Why you do so much re-uploads??
i am not an engineer but i understand clearly what is an mcb, thank you guys for the clear explanation
It's working principle is like rellay?

I just realized these animations are of the same quality as the first Toy Story movie.
What if the current going through the MCB is going in the other direction when there is a short circuit? Wouldn't the electromagnet not function properly because the magnetic field would be in the wrong direction? By the way, nice video!
Whatever be the direction of Field, in either case it attracts the iron plunger causing the MCB to trip.
What an Amazing explanation that was!
Nice content👍👍👍🙂🤝

Wow your videos are so good and detailed😀😀
You are very intelligent guy
That's some great stuff.
IT is amazing and great thing then a best method
This was a really great presentation!!!
how does a breaker protect against the stupid who force the lever up with some wire? Apparently some breakers still trip in that case.
This breaker design wouldn't protect against it. It will burn down your building if a janitor leaves the broomstick under that main lever. The US-style breakers are safer than this particular MCB design.
