How To Select MCB Breaking Capacity, MCB Breaking, Breaking Capacity of Mcb, Miniature Circuit Breaker, In English

A friend today we'll talk About How To Select MCB Breaking Capacity, MCB Breaking, Breaking Capacity of Mcb, Miniature Circuit Breaker, In English

Friends, if you look carefully, there is one MCB and one isolator. Time to buy an MCB You have to pay attention to this thing It may not be that you go to MCB and take the isolator Because the MCB's price is expensive and the price of the isolator is low, it is very important to know what the shopkeeper is giving you.

MCB protects us with two types of a short circuit protection and the second overload protection Overload means anything that is taking you much more to your capacity, according to your load, it will do the same time trip, after how long it will trip or depend on which type of MCB is made of which category

And the short circuit means that due to the touch of neutral and phase anywhere, it is called a short circuit. If these cases occur in a short circuit then if your MCB is trip takes you a few milliseconds, Instant short circuit protection is used for that

Friends need to understand your diagram

As you can see, which is called circular in the diagram, we call it overloaded procation or thermal protection which is our squre. It is a short circuit protection. Magnetic trip also we can say it in case of short circuit.. 

Friends, now we talk about the main issue of this video, which is written on 6000 here, Friends MCB symbol round type is our Overload Protection

As I told you this means that this MCB can have a current of 6000 milliseconds if the current flows through more than 6000 milliseconds then it will be a MCB trip. So this number reflects its breaking capacities and MCB will not do the work, 

the trip will be named. The value of the name is ICN, we people say that the breaking capacities of our MCB are 6000

After that, which is written here, 3 means that our tripping system will trip in how many milliseconds if 3 milliseconds have been written here, that means 3 milliseconds should be tripped for this purpose, It has been written that its breaking capacitance is written in milliseconds

Friends so little will have our breaking capacities, Equally, our protection will increase, MCB overload protection and short circuit protection. MCB' We can use in Residential Commercial and Industrial
