✅ CHINT 197931 – NB1L-40 RCBO – 1P+N, 10A, C Curve, 30mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 RCBO offers combined protection against overloads, short circuits, and earth leakage currents in a compact 1P+N unit. With a 10A rated current, C-curve tripping characteristic, and highly sensitive 30mA residual current detection, it is ideal for safeguarding people and equipment in lighting circuits and residential applications. This RCBO provides a 6kA short-circuit breaking capacity and is designed for AC-type residual current faults. It operates at 50/60Hz and complies with IEC 61009-1. The thermal-magnetic trip mechanism ensures fast disconnection under fault conditions, while its integrated leakage protection prevents electric shock and fire risks.
