RCB (Residual Current Breaker) and MCB (Miniature Circuit Breaker) are crucial for electrical safety and circuit protection. An RCB, also known as an RCCB (Residual Current Circuit Breaker), detects imbalances in electrical currents and quickly disconnects the circuit to prevent electric shocks and fire hazards. It is essential for protecting against earth faults and leakage currents. On the other hand, an MCB provides overcurrent protection by automatically switching off the circuit when it detects a current exceeding its rating, thereby preventing overheating and potential damage. While RCBs focus on safety against leakage currents, MCBs safeguard against overloads and short circuits. Together, they enhance overall electrical system reliability and safety.
