Question
What is MCB? Why is MCB preferred to electric fuse?
Open in App
Solution
MCB is more sensitive to current than fuse. It
detects any abnormality in the current flow and automatically switches off the
electrical circuit. In case of MCB, the faulty zone of electrical circuit can
be easily identified. Faulty circuit trips to the off
Fuses are faster to disrupt the current flow
but they must be replaced after a piece of metal melts down, whereas circuit
breakers can be reset and used multiple times. The most significant
distinguishing factor between fuse and circuit breaker lies in their
operational mechanism.
