✅ CHINT 200224 – NL1-63 RCCB – 4P, 40A, 30mA Sensitivity, AC Type, 6kA Breaking Capacity Description (English): The CHINT NL1-63 RCCB is a 4-pole, magnetic-type residual current circuit breaker engineered for reliable protection in three-phase + neutral power systems. With a rated current of 40A and 30mA sensitivity, it is designed to protect users from electrical shocks and reduce the risk of fire caused by earth faults. This AC-type RCCB detects pure sinusoidal alternating current leakage and provides a short-circuit breaking capacity of 6kA at 230/400V AC. It operates at 50/60Hz and supports sensitivity classes AC, A, G/SI, and S, offering broad protection coverage. Equipped with double terminals (DB), this unit ensures simple and secure installation. It is certified by CE, Intertek, EAC, and SAA, and complies with IEC/EN 61008-1 standards for global use.
