Tips: Difference between RCCB and MCCB breaker

RCCB (Residual Current Circuit Breaker) and MCCB (Molded Case Circuit Breaker) serve different purposes in electrical protection.

RCCB detects earth faults or leakage currents, protecting against electric shocks and preventing fire hazards. It works by comparing the live and neutral currents; if there's a difference (indicating leakage), it trips the circuit. RCCBs are typically used in residential and light commercial installations, focusing on human safety rather than overload protection.
MCCB is designed to protect against overcurrents (overload or short circuit). It is capable of handling higher current ratings and is used in industrial and commercial applications where higher power is distributed. MCCBs can be adjustable and provide both thermal (overload) and magnetic (short-circuit) protection.
