Time Current Curve Basics: Determining Circuit Breaker Trip Times
Vložit
- čas přidán 18. 09. 2017
- Every circuit breaker has a characteristic curve that reports the manner in which it trips. As this curve is reporting the amount of current vs time, it is aptly called a Time Current Curve. Learning to read these curves allows you the ability to quickly understand the tripping characteristics of the circuit breaker being reported by the Time Current Curve.

This guy knows his work as his pocket.Great job sir thanks a lot.
This was perfect! Clear and straight to the point. Thank you!
Fantastic explanation of the TCC. Looking forward to further videos.
Thank you for this simple but well explain lesson Schneider.
Thank you Schneider for this wonderful lesson
Beautiful explanation. More electrical engineers need to see this
Wow, No words to say. Thanks help a lot. Thanks again,
God bless
Very helpful and straight to the point. Thank you.
waaaaw. simply great. this man is a real teacher
Schneider is always the best... Thank you for the knowledge that you share ❤️.
Please MAKE us EDUCATE of all oa your product that will be released...
THANK you 💖
Glad this is still available. Thanks
Great video! Thank you for helping me with my homework!
Awesome video mate! Really helped me understand
Very clear explanation...thank you sir
Perfect and straight to the point
thanks for such a great video! big up
Awesome video, very informative!
Very good explanation. great video. very clear
Great explanation!
I have an outdoor circuit that breaks after less than a minute of delay. The circuit feeds 4 gate poles, I was able to isolate the short to one of the poles. Any suggestion why the breaker trips after several seconds and not instantly.
The numbers shown at 7:42 represent the time dial of a given setting. By increasing the time dial, you are increasing the minimum response time (shifting the curve upward). The shaded region represents the minimum and maximum response time. (The breaker should trip within the time specified). You can coordinate multiple circuit breakers in series by ensuring the curves of different breakers do not overlap.
If downstream breakers are in parallel, you may have to account for different levels of current seen at each point.
Clear and good explanation
Thank you. Great presentation.
Nice video information!
What does HACR rating do? What is its characteristics? How is it different from other MCBs
Great explanation, thanks a lot
Please have a brochure with size of cable damage curve coordinated with circuit breaker
Thank you It's simple and easy to understand
Glad it helped!
Thanks
It is very helpful.
In sepam relay setting in etap
Regarding to the instantaneous trip , is it necessary to be set with new element or with the previous over current element. Also regarding to the ground fault trip what we should select?
Thank u dear
Great video!
Is coordination study required for both Series-Rated and Fully-Rated?
Catching the Electronic Trip Unit at 8:01 was awesome... I would say, you could try for the Olympics next year.. 😀
ON IT! Training for Summer 2024...
Really this video helping so much for me . Understanding about Electrical triping curve
Thank you
Excellent explanation. Thankyou.
Glad it was helpful!
thanks
Air circuit breaker contact resistance value kitni hoti hai. ?
This is great 👍
Amazing 👏
Answer this question for me if you know?why in england dutch germany we use curve b and in france italy we use curve c,What is the use of the 1p + n circuit breaker,
and why monopolar circuit breakers are used in some countries and in others 1p + n?
Maybe make some videos about these topics
Time for another video.
Do you have a video one how to read or pick your cascading circuit breaker
Are you asking about circuit breakers for series or fully rated systems? A bit more info please...
Great clarify
this is a very informative video .... subscribe is done.
Anas Nori Thanks! We have more on Circuit breakers coming soon. We just released a few yesterday on PowerPact mounting options, how to determine interrupting ratings when you encounter a need to substitute a PowerPactTM for one of of our legacy MCCBs, and an intro to our MicrologicTM electronic trip units.
Anas Nori 👍
great
Nice sir
Hi I like your video
Excellent explanation
Glad it was helpful!
What happens to the TCC if OCPD is 80% Rated?
Nothing
my friend Alif want to know.. do you love your job ? and how to setup a fuse in ETAP software ?
no I hate it. No I dont set up fuse
thats great
Thanks.video is useful for me.
Thank youuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
Great 💪💪💪
I have been waiting for the other videos
Thanks, Zunaira. They are in development. Hope to have them uploaded soon.
Zunaira Ghaffar, we just released yesterday more videos on PowerPact mounting options, how to determine interrupting ratings when you encounter a need to substitute a PowerPactTM for one of of our legacy MCCBs, and an intro to our MicrologicTM electronic trip units. We should have more coming in the February/March timeframe. Enjoy and take care!

sir how to find faults in load side...By Acb
Greetings, Syed. Can you please explain more of what you mean by "Acb"?
Square D by Schneider Electric ACB means Air Circuit Breaker
OK
Good video but the volume is just too low
Why does such a knowledgeable man continue to keep his speech in such poor condition, they have classes to fix it. Great video.
Makes him even more Authentic
ground fault square d
@6:16 17/1000* not 17/100
This got me trippin
Zhang Zhixuan.😁
awesome explanation. u did great dude. But still have to say. Why not choose a man who speaks more clearly? (no hate)
Haha that throw was really cringing. Good video though.
You earn loads of money DONT foukn read but explain !
Thank you
Thank you
Thank you
