MCB (Miniature Circuit Breaker)
MCB (miniature circuit breaker) is electromechanical protector which protects from low voltage electric network instead of fuse. It protects the wiring from severe damage caused due to very high or low voltage. Which is to be carried a current which is too high for the diameter of the wires.
MCB's main function is to break the consistency of electric flow if any error detected. Rearranging MCB devices are very simple thus it gives better protection at reasonable cost.
If the current flow exceeds the maximum acceptable limit the MCB works as switch which will turn off in such condition. It protects from overloading, short circuit and switching.
