The MCB-Miniature Circuit Breaker. An MCB is a form of fuse (protective device) which overcomes the traditional problem associated with fuses in so much as when one blows it does not need to be replaced as a fuse does or in older fuses, the wire does not need replacing.CB's operate when they sense an overload, or over current, and become an automatic switch, turning off, or tripping, the MCB when it detects such an overload.
Short answer: You will need RCCB (Residual current circuit breaker) since it is especially meant to protect against electric shock hazards to humans. MCB is mainly used to protect your device from an overload current in case of some internal short circuit fault in your device.
