What kind of safety does a miniature circuit breaker MCB provide?

• Miniature Circuit Breaker (MCB) is a switch which automatically turns off when the current in a circuit exceeds the safe limit and prevents other electrical appliances from damage.
• MCBs basically disconnect the electrical devices from the power supply whenever there is an overload or short circuit and prevents electrical damage and fires.

Therefore, we can say that MCBs grant overcurrent and short-circuit safety to our devices.
