General
Residual Current Circuit Breakers (RCCBs) are vital safety devices that detect current leakage (typically 30mA-300mA) and instantly cut power to prevent electric shocks or fires. Compliant with IEC61008-1, they offer 10kA short-circuit protection and operate at 230/400V, 50/60Hz. Widely used in homes/industries for grounding fault protection.
