✅ CHINT 200231 – NL1-63 RCCB – 4P, 63A, 300mA Sensitivity, AC Type, 6kA Breaking Capacity Description (English): The CHINT NL1-63 RCCB is a high-capacity, 4-pole residual current circuit breaker built to provide effective protection in large-scale three-phase + neutral installations. With a rated current of 63A and 300mA sensitivity, it is ideally suited for industrial and commercial environments where insulation faults or earth leakage could lead to equipment damage or fire hazards. This AC-type device detects pure sinusoidal leakage currents and provides a robust short-circuit breaking capacity of 6kA at 230/400V AC. It operates at 50/60Hz and supports AC, A, G/SI, and S sensitivity classes for extended protection applications. It features double terminals (DB) for secure, flexible wiring, complies with IEC/EN 61008-1 standards, and is certified by CE, Intertek, EAC, and SAA, ensuring safe, globally approved operation.
