Working Principle of Miniature Circuit Breaker

MCB online circuit breakers are the most popularly used model for the safeguard of the points of electricity. It works as a safeguard against short circuit, excess load, excess voltage etc in both systems of single and three phases with rating of current up to a limit of 125A.It usually accommodates four kinds of 1P, 2P, 3P and 4P. It is set up having the capability to operate having contacts with mechanism, all safeguard equipments etc. Let us have a look at the working principles of the said circuit breaker.

•    The operation of the MCB Online circuit breaker from excess load is based on the principle that strips of two metals wielded together change the positions with a rise in temperature. When miniature circuit breaker is operating under normal circumstances, the inner part of the two metals that are welded together gets heated with the flow of electric current. The angle of bending gets much wider when excess load occurs so that the metal strips that have changed positions touch the lever in the mechanic system which has tripped. It then allows the catch on the mechanism to act as a switch to indicate overload thus working on the principle of safeguarding excess load.

•    It also safeguards short circuit. The process of a force produced by a pressure difference which is developed under normal operation of the current is not sufficient to withstand the spring’s force of reaction resulting in further working of the circuit. But when there is severity of excess load big amount of current will still pass through induction coil and a magnetic field that is strong is developed.

•    A suitable curve that has got special qualities is essential to make the right choice of buying a perfect circuit breaker.

To conclude we can say that MCB online circuit breakers can operate as residual current circuit breaker with excess load. If it is operating along with RCD, RCBO that is fitted inside the distribution box then it can safeguard people from the shock of electric current.

Hope the above discussion on the working principle of Miniature Circuit Breaker clearly explains the process in which the miniature circuit works.  You can also seek the assistance of an electrical engineer to know about the working process of MCB.
