✅ CHINT 198068 – NB1L-40 RCBO – 3P+N, 20A, C Curve, 30mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 3P+N RCBO is engineered to ensure safety in three-phase systems, with reliable overload, short-circuit, and earth leakage protection. It is rated for 20A with a C-type tripping curve and 30mA sensitivity, ideal for circuits requiring rapid disconnection in case of fault current or personnel hazard. With a breaking capacity of 6kA and AC-type residual current detection, this device is suitable for lighting, socket circuits, and mixed commercial installations. It complies with IEC 61009-1 and operates at 50/60Hz with a thermal-magnetic trip mechanism integrated with leakage protection.
