Circuit Breaker

Circuit Breaker is one of the automatic electrical circuit breakers, due to the more current passing through the circuit breaker. Circuit Breakers are usually abbreviated as CB, because the electric current is excessive. One example is that it is in your house, if an electric current that is over and uninterrupted, it can fire the house.
This circuit breaker has a function that is to break the connection between the side of the power source and the load side which can work automatically when a disturbance occurs or manually when done maintenance or repair.
This circuit breaker is in principle the same as the MCB function in our home electricity meter. If there is an electrical short circuit or excessive use of electricity, then all electricity will automatically be cut off or die of electricity.
