✅ CHINT 198391 – NB1L-63 RCBO – 1P+N, 50A, C Curve, 300mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-63 RCBO is a high-capacity residual current breaker with overload and short-circuit protection, specially designed for demanding electrical systems. With a 1P+N configuration, 50A rated current, C-type tripping curve, and 300mA earth leakage sensitivity, it is ideal for fire protection and equipment fault isolation in heavy-load installations. It provides a short-circuit breaking capacity of 6kA and detects AC-type leakage currents. The unit is compliant with IEC 61009-1 standards and operates at 50/60Hz. Integrated thermal-magnetic tripping with fast leakage detection ensures enhanced safety for circuits carrying significant electrical loads.
