Well, we have MCBs in our house, and let me inform you that MCBs are a must. An MCB, or miniature circuit breaker, automatically switches off the power supply when there is an overload, short circuit or high voltage. So the answer to does MCB protect from high voltage is yes. I am even aware of how it works, so I can share some insight about it here.
How Does MCB Protect from High Voltage?
An MCB is specifically designed to protect electrical circuits from overcurrent and short circuits. Here is how it works:
MCBs have current ratings, so when the current flow exceeds that rating, the MCB trips and breaks the flow of the electric current
MCBs have two contacts, where one is fixed and one is moveable. When the current increases beyond the safe level, the moveable contact drifts away, creating an open circuit
So this is what an MCB is and how it works to prevent damage to the electrical systems and unseen hazards.
