✅ CHINT 198079 – NB1L-40 RCBO – 3P+N, 25A, C Curve, 30mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 RCBO is a high-performance residual current circuit breaker with overcurrent protection, designed for critical three-phase applications. With a 25A current rating, C-curve tripping characteristic, and highly sensitive 30mA leakage detection, it delivers fast isolation to safeguard personnel and equipment. This device offers 6kA short-circuit breaking capacity and supports AC-type residual current sensing. It is ideal for commercial and industrial environments where both overload and leakage protection are required—such as machinery, socket outlets, and lighting in three-phase networks.
