MCB breaker, Ultimate short circuit current (Hindi)

The MCB circuit breaker, Ultimate (Icu) and service (Isc) short circuit current capacity of the MCB circuit breaker are explained in Hindi in this video tutorial. The difference between Icu and Ics electrical current capacity of the miniature circuit breaker or any other circuit breaker like MCCB is also explained with a calculation example. The test sequence for defining the ultimate and service short circuit capacity is also explained in detail. Educational video and learning tutorial on electricity & electrical engineering in Hindi 321 by G K Agrawal (person with industrial experience).

You're great sir. Very useful video. Thank you.

[@sanjeevrana8317]

Impeccably Authentically excellent

[@loveswinhate]

Great explaination. One problem to find out the short Circuit value of current. It is possible in micro processor based breaker only.

[@jenas11000]

Good work sir. God bless you and God give you good health.

[@shivahara4031]

very nice video

[@kv848]

Great info sir..
For our purpose, how to decide which percentage of Ics (25 or 50 or 100 %) we need ?

[@Munaam1989]

Thanks Sir,
From Pak💚🇵🇰

[@boloharekesaharekejaijai4003]

Thanks Sir

[@fahimasghar6375]

Very useful video Sir. Please make videos of MCCB,ACB and VCB.Thanks a lot

[@GKAgrawal2]

Videos on MCCB and MCB is already there in Hindi and English both versions.

[@RajElectricalsLatur]

Nice sir

[@pankajsanwal2010]

नमस्कार सर , आपके इस वीडियो का टॉपिक बहुत उपयोगी था । लेकिन जैसे ही तत्व की बात जानने का समय आता है तो अक्सर एक आवाज सुनाई देती है कि "अब आज यहीं समाप्त करते हैं " तभी बड़ी निराशा होती है कि काश आपको contact करने का कोई जरिया होता तो कम से कम हम अपने indivisual doubt तो clear कर लेते । धन्यवाद ।

[@pankajsanwal2010]

सर air circuit breaker के short circuit current , earthfault को समझाने के उद्देश्य से release का एक वीडियो अवश्य बनायें । धन्यवाद ।

[@jigneshshah7594]

So nice sir

[@Mini-jl9jr]

Thank you so much sir

[@electricallearner]

Sir tpn MCB 32 amp to Singal phase ma ketna amp hoga

[@fahimasghar6375]

Sir i have request to you please tell us that due to power failure or short circuit how will ACB and VCB breaket will open.Thanks a lot

[@jitendrayadavvlogs2326]

braking capacity calculation vidio sir bnake upload krdijiyen

[@IrfanKhan-rn2ht]

Thank you

[@muqtardm]

Sir Icm aur Icw bhi explain Kare thanks

[@maikulalpal7781]

ये सारे टेस्ट mccb बनाने के बाद किये जाते हैं या फिर प्रॉब्लम के बाद किये जाते ।

[@GKAgrawal2]

MCB बनाने के बाद

[@umagiri4182]

Sir ocb ACB breaker ki wirring connection batao load or Amps bee

[@poojasharma-kj1fr]

Namaste sir, sir kisi ckt m transistor ke base ko touch karne pe jittering sound aa raha hai aur current bhi increase ho jaata h.isko rectify kaise karen.plz batayen sir

[@GKAgrawal2]

Mera video BJT in hindi dekhiye. Usmey eska solution bataya hai.

[@poojasharma-kj1fr]

@@GKAgrawal2 sir wo mene dekha h,jo aapne base pe resistance lagaya hai wo sab mene kar k dekh liya,but uski jagah capacitor lagane pe sahi ho raha h.

[@GKAgrawal2]

Capacitor laganey sey Transistor ON OFF slow hoo jayega aur high frequency per problem aayegee. Agar aapkaa use very slow type hai then capacitor is OK. But base driver per load jyada hogaa.

[@jitendrayadavvlogs2326]

Sir agar Icu=10ka hai
aur Ics= 5ka hai
short circuit hone ke bad curent Ics curent se jada flow ho rha ho like 6KA to kya hoga sir

[@GKAgrawal2]

Mera dusra video " MCB Let through energy class" dekho

[@kv848]

After the first trip, atleast after 3minute you can close it and then again if it trip, you need to repair it for further use...

[@GKAgrawal2]

Comments welcome

[@RajElectricalsLatur]

Sir aapke whatsapp group me add kijiye na

[@BIPINAHIR]

Dear sir Namaste maiy chahta hu ki aap aek aesi video banayye Jisme motor according contactor selection kaise kar sakte haiy example ke liye 1 HP 3phase induction motor ke liye Kitne amp ka contactactor use hoga thanks

[@adnansaeed175]

Are lcu ane lcn same?

[@shariqkhan7411]

Sir if icu equal to ics then the breaker should be usable or it may require repairing

[@GKAgrawal2]

It will follow Ics rule. Icu does not mean that it will always need repair, it may need repair and to be checked. Company can always design much better quality breaker than specified.

[@adnansaeed175]

Are lcu and lcn same?

[@GKAgrawal2]

1- Both are defined in the different standard. Icn is as per standard 60898-1, while Icu is as per standard 60947-2
2- The MCB shown in this video confirms to both the standards and have a different value for both. Icn = 10000 amps, while Icu = 15kA, these are written on the MCB itself. You can see this on the image of MCB in my another video " meaning of data on MCB rating plate"
