    MCBs are more reliable and safer than fuses.

    • MCBs can be reset and reused, while fuses need to be replaced after every trip

    • MCBs have a faster response time than fuses, which can prevent damage to equipment

    • MCBs have better overload protection than fuses

    • MCBs are more convenient to use as they do not require replacement every time they trip

    • MCBs are safer as they do not release harmful gases or debris when they trip
