✅ CHINT 197929 – NB1L-40 RCBO – 1P+N, 10A, C Curve, 300mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 RCBO is a compact and multifunctional protective device combining overload, short-circuit, and earth leakage protection in a single 1P+N unit. This model features a rated current of 10A, C-type tripping curve (5–10In), and high 300mA sensitivity, making it suitable for equipment protection and fire prevention in residential or light commercial installations. With a 6kA breaking capacity, it can reliably interrupt high fault currents. The device supports AC-type residual current detection and operates at 50/60Hz. It complies with IEC 61009-1 standards and integrates thermal-magnetic tripping and leakage protection in one module.
