Показать описание
In this video I have practically explained the followings:
1. How the MCB (miniature circuit breaker) work?
2. Inside of the circuit breaker (MCB)
3. The function of the different components inside of MCB.
4. How the circuit breaker works to protect against overloads and short circuits faults.
5. I have explained how the thermal and magnetic tripping device trip the circuit breaker during a fault.
6. Some circuit breaker (MCB) ratings such as i) Voltage rating, ii) Current rating
7. Different types of MCB – B-type, C-type & D-type and how to calculate the tripping current of each type of MCBs.
8. How to connect MCB in a circuit.
9. What are the features of MCB?

Nonsense alert! That the tiny CB shown at 0:30 is a 10 Amp breaker. It will NEVER carry 10 000 Amps! It would already vaporise - yes VAPORISE - at much less than that - probably start melting at 100 Amps!

Can you even imagine what size of device would work with 10000 Amps of current??? A power station generator! Imagine THAT going through this breaker - what a cartoon that would be!
