CB is rated as 2500A, 1500MVA, 33KV, 3secs; 3-phase oil C.B. Determine the rated symmetrical breaking current, rated making current, short time rating and rated service voltage.
Previous video u just changed hp into kw and then u calculate the ampere but here u convert the kw into KVA then u calculate the ampere........u r just making the video but not in proper way....Not cleared ||

Sir apnay 25 % ka saftey factor 1.25 kasay liya jabka ye 0.25 ata ha
Bhai MCB me KVA ka kya kam direct kw se hi FLC nikalona and next thing 25% ka matlab 1.25 nahi hota 125% ka hota hai so 125% of FLC is correct
Bhai 125 % yani 1.25 hota hai tu divide kr k dekh
When you calculate the single phase current you should also calculate per phase power which is divide by 3 of 3 phase power which you have not done
Thank you very fruitfull for us now moreover would you guide us selection of breakers accordingly ICU, ics, Icw. So nice of you
Bhai residential load different huty hyn iron freezer tu uska kysy nikly ga
2 ton ka 10 ac chalane ke liye kinte ampire ka mccb sahi rahega plz reply Iam from Nepal
4 Stabilizer hai, 15kva, 15kva, 15kva, 15kva, ka. double phase stabilizer h, mccb kitna selection karna hoga, or kva mccb hona chaiye
Sir three phese wairring me main mcb ya elcb ka selection single phese ya three phese ke hisab se chayan karenge
hamare ghar me 2000watt ke ek gyser,2000watt ke induction,iron,motor, freeze,8 ceiling fans,2 tv,aru lights ke liye kun sa rccb mccb use koru?
Sir..200V 3PH,3wire incoming supply hai 400 A ka MCCB lena hai to mccb ki breaking capacity kitni lena padegi..50 KA min breaking capacity req.hai..
22000 watt ke liye kitna amp ka MCCB lagega 230volt par
Sir circuit breaker selection vale ye example me apne current nikal ne vale formule me kw ka istemal kyun nahi kiya..?
Plz bataiyega muje janana hai
Me app ki vdo bahut dekhatahun
sir ji hame 50kw ke ley mccb men swchit lagama hai
Agar same rating ka MCCB & ACB hai to kaun sa circuit breaker lena chahiye
Nice bro.... really good one
Super fainstatic sir,
Mccb का breaking capacity (KA)kaise सिलेक्ट करते है
great
Rele par video banaye sir
20 k.w 3phase k liye kifne ampere ka mccb lgana pdega
Sirji current nikalneke liye power factor ki jarrurat nahi hain kya?
How to MCCB select breaking capacity
How choose mcb,mccb,vcb,acb,sf6 ??ye bhi batao bhai
How to select braking capacity rating of MCCB
15 H.P. की मोटर के लिये कितने amp की MCCB लगेगी
How to find KA rating in MCCB??
Thanks sir !!
100A rating mcb ki hai ya mccb ki hai?7
nice
Good
Jo ghar me use karte ye sub batao
Short formula used plz
How to find ka rating of 1 pole MCB 40 a
Voltage rating kaise calculate karna hai???+
25% is 0.25
how 1.5?
its 1,25 % of the load current , which is1.25
54hp kee motor MCB ka chayan Kiya jata hp *3 is per 150 mccb lagni chahie
Bhaijaan, MPCB ka size kaise calculate karna hota hai?
What about OL and contactor for this load?
Safety factor is not 25% because 25% is 0.25 so we should use 125% safety factor 1.25
If 3pole mccb 160 amp what does its mean per pole 160 are total amps 160
How we come to know where we use MCB ,MCCB OR ACB
1.25 kaise calculate kiya apne
braking capacity kaesa selction kare.
How many single phase16 Amp Mcb can be loop in each phase of 63 Amp 3Phase MCB
12
why You not consider pf in calculation
Previous video u just changed hp into kw and then u calculate the ampere but here u convert the kw into KVA then u calculate the ampere........u r just making the video but not in proper way....Not cleared ||
70*25=17.88=88 yah sahi hai
what about breaking capacity??
Bhai KW को KVA मे क्यो convert किया
Mccb me kA rating mining
What about remaining breakers
25 % how 1.25
What is Power sector?
Its a power factor ,cosine angle between current n voltage.
Ka ??? 10/25/36/50????
How you calculated 1.25...For 25%
Mai bhi yahi sochta hu
Y wd 25%multiplied
Bhai your current calculation is wrong
Nice
