Mcb and Rcb what is different?

Question

Accepted Answer

Mcb is a miniature circuit breaker used for overcurrent protection, while Rcb is a residual current breaker used for earth fault protection.

Mcb protects against overcurrents by automatically switching off the circuit when a fault is detected.
Rcb protects against earth faults by detecting imbalances in the electrical current flowing through the circuit.
Mcb is commonly used in homes and buildings to protect against short circuits and overloads, while Rcb is used to prevent electric shocks from faulty appliances or wiring.
Mcb typically has a higher current rating than Rcb, as it is designed to handle larger overcurrents.
Both devices are important for ensuring electrical safety in a building or system.
