Nowadays 2 Pole MCCB Also available in Market. MCCB Rating starts From 32 Amps. Another Diffarance between MCCB & MCB is that there is a Single switch or Mechanism in MCCB to On or Off the device but in case of 2,3&4 Pole Mcb there are separate swithes & Separate Tripping Mechanism and All Separate MCBs fixed commonly with revetting rods,Swithes also collaborated with Common Rod.🙏
Small corrections : 1) There is a shunt trip option for some types of MCB, 2) Current ratings for MCCB start from 40A not 100A and go up to 3200A not just 2500A. 3) Most important differences between MCB and MCCB is (as you stated) the larger Icu, and DURABILITY (service cycles).
A few mistakes I've noticed - MCB's nominal current goes anywhere from 0.5A to 125A - MCCB's nominal current goes from 16A to 3200A or even 4000A - MCBs can absolutely feature auxiliary or alarm contacts and/or a shunt trip. Schneider's A9A26909 is an auxiliary+alarm for iC40/iC60 MCBs, for example - the breaking capacity of an MCB goes anywhere from 4.5kA to 100kA. Schneider's iC60L and NG125 go up to 100kA if I recall correctly. - MCCBs also exist in 1-pole and 2-pole configuration, although they're quite rare - 7:34 The Ics is the current that can be safely and repeatedly interrupted by the breaker. In your example MCCB, you can break 35kA (=Icu) but the breaker will probably be toast after it. If you don't want it to be toast, stick to 25kA (=Ics) or lower and you'll be fine.
good information
Thank you for sharing your knowledge
Super

Well dane, thanks.
Thanks
great information ❤
U r great teacher
More power to u
beautifully explained.. Thanks
Nice,next video show us types changeover
Good information but know that there's MCB of up to 120A as well as MCCB of 32A.
True, MCBs go up to 125A, while MCCBs go from 16A to 2500/3200/4000A

Current ratings for MCCB start from 16A not 40A
Super dude , subrscribed ,, thanks for new learning to me
Very good class. Please make a video related IEC and NEMA electrical standard
How are you doing Friend
In M C B which is out put and in put
Good video. MCB also can be provided with aux. Contacts
