✅ CHINT 198413 – NB1L-63 RCBO – 3P+N, 63A, C Curve, 30mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-63 RCBO is designed for maximum safety in high-risk three-phase + neutral systems. With a rated current of 63A, C-curve tripping, and a sensitive 30mA earth leakage threshold, it provides rapid disconnection to prevent electric shocks and equipment damage in industrial, commercial, and mission-critical installations. Featuring AC-type residual current detection and a 6kA short-circuit breaking capacity, this unit ensures strong protection for circuits with high current demands. It is compliant with IEC 61009-1, operates at 50/60Hz, and integrates thermal-magnetic tripping with precise leakage fault response.
