A circuit breaker is a kind of electrical switch which is automatically operated. The circuit breaker is planned to save an electrical circuit from overload or short circuit. The main function of a circuit breaker is, it interrupts current flow after a fault is detected. Though fuse is also used for the same purpose. But the fuse is not efficient. When there is a fault detected, there is a need to change the fuse every time. On the other hand, a circuit breaker can be reset to its normal operation either manually or automatically.

The circuit breaker is made in different sizes. A small size circuit breaker protects low current circuits. It is also used in a residential area for individual household appliances. The large-size circuit breaker is designed to protect high voltage circuits. It can protect the entire single city. An automatically operated circuit breaker means, it is removing power from a faulty system. That is also known as the Over Current Protection Device.  Circuit breaker More Information.
