As shown in curves it take a specific time to trip, moreover why we are choosing the MCCB rate current to be equal 1.25 full load? As example: heater current = 12 Amp MCCB ==> B16
Thank you for your question 😊 we increase mccb rating current for protection purposes,, to take into consideration the temporary overload current and inrush current
Can this type of MCB be used like a main isolator switch in a single phase installation (meaning the incoming phase and neutral are connected pole to 1&3 respectively and their outputs will be pole 2&4 respectively)?
@@lanzrilpangilinan8272 welcome to my channel and thanks for support ❤️❤️,, you can watch this video and you will understand completely frame current and rated current ua-cam.com/video/GgfmwWFZ43A/v-deo.htmlsi=X1WYN50hOWPsb9Y2
So a C16 MCB will keep working if 16amps current drawn by a AC stabilizer (100% rated current load @ 230 volts ) runs through it day n night 24*7 ( in case of inverter AC ) & will only trip when amps exceed 10 time the rated amps (short circuit ) or voltage drops ( below 200 volts ) and AC stabilizer starts drawing more amps causing overload situation right ?
Yes that's right, if current exceeds 16amps (let's say 18amps for example) after a time that you can calculate on the curve the breaker will trip, this increase of current could be because of drop in voltage or increase of load(power)
To determine if a Miniature Circuit Breaker (MCB) is reversible or not, you can check the following aspects: 1. Manufacturer Specifications: The easiest way is to refer to the MCB's datasheet or user manual, where manufacturers often indicate whether the MCB is reversible (i.e., whether it can be installed in either direction). 2. Markings on the MCB: Look for any directional arrows or labels near the terminals that indicate "Line" (input) and "Load" (output) connections. If such markings are present, the MCB is not reversible, meaning it must be installed in a specific direction. 3. Pole Design and Contacts: For some MCBs, especially older models, the internal contacts are designed to only safely operate in one direction, based on how the arc is extinguished during a trip. If the MCB is marked as unidirectional, it's likely not reversible. 4. Visual Inspection: If the MCB has distinctive inlet and outlet terminals that differ in size or shape, this indicates that the MCB is not reversible. If both terminals look the same and have no directional markings, it may be reversible. 5. Testing the Reversibility: If you are unsure after reviewing the manual and inspecting the MCB, you can test it by wiring the input and output in reverse and observing if the breaker still functions normally, though this should only be done by a qualified electrician for safety reasons.

Great work in producing this type of video.
Would you explain in more detail the energy class (1, 2 & 3) please
Regards John
Thank you for your support ❤️ sure i will create a new video for you
Thanks Sir for a lovely video on circuit breakers
Thank you for your support ❤
Just what I needed! Great!
I'm happy to hear that 😊 thank you 😊
Thanks for brief details
You are welcome 😊🙏
Thank You Very Much, Sir.
You're welcome 😊🙏
Weldon, your explanation helped.
Thank you for your support 🙏❤️
How to really identify polarized and non polarized mcbs? Most of them are marked with (+ )ve & (-)ve symbols.
شكرا لك من السعودية انا احب ذلك
Thank you 😊❤️
Thank you for sharing good news
Thank you for your support 🙏❤️
Wow, amazing, i like this video
👍
Thank you 😊 stay tuned for more useful topics in the future

You're welcome 😊🙏
what is the difference between AF and AT circuit breaker ratings ? thank you
Hi, are fuses also have this kind of tripping curves? Or this only apply for MCB only? Thanks for your assist!
thank you for this question, no it doesn't have these tripping curves
very useful . Than u very much
Thank you for your support ❤️🙏
Hi I'm from the Philippines, I wanna know the difference between ampere trip and ampere frame of the circuit breaker ...thanks and more power.

3:23 Isn't that Icn ?
5:24 If 6000 is Icu, why i don't see the value of 6000 under Icu?
Sir how can identify if reversable or non reversable?
Good video
thank you for your support🙏
Why there was no operational symbol on the second mcb?
If there is no operational symbol so you can connect supply to either side
What is frame rating in mcb?
3 phase how to install in 2phase

Amazing

great 😊😊

Very Useful 👍
Thank you for your support ❤️ 😊
not saying anything about C60N .. ???
1:25 ,this is the product number, you can use it along with catalog number to find out the breaker on internet
C20 code ka meaning batao
Thank you, Can you please clarify your question
me like it
