✅ CHINT 198410 – NB1L-63 RCBO – 3P+N, 50A, C Curve, 30mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-63 RCBO is a high-performance protective device designed for sensitive three-phase + neutral applications. With a rated current of 50A, C-curve tripping characteristics, and a 30mA residual current sensitivity, it ensures immediate disconnection in case of earth leakage faults—offering enhanced safety in critical power systems. This 3P+N RCBO is suitable for industrial distribution panels and commercial facilities with high operational demand. It features a 6kA short-circuit breaking capacity and AC-type residual current detection, operating at 50/60Hz. Compliant with IEC 61009-1, it integrates thermal-magnetic protection and rapid leakage detection.
