Question

Accepted Answer

Circuit breakers are needed in electrical systems to protect against overloads and short circuits.

Circuit breakers help to prevent damage to electrical equipment by interrupting the flow of electricity when an overload or short circuit occurs.
They provide a safety mechanism to quickly disconnect power in case of a fault, reducing the risk of fire or electrical hazards.
Circuit breakers can be reset after tripping, unlike fuses which need to be replaced.
They come in different types such as thermal, magnetic, and thermal-magnetic circuit breakers.
Examples of circuit breakers include miniature circuit breakers (MCBs) and molded case circuit breakers (MCCBs).
