✅ CHINT 197947 – NB1L-40 RCBO – 1P+N, 25A, C Curve, 30mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 RCBO is an enhanced safety device that integrates overload, short circuit, and earth leakage protection into one compact 1P+N unit. With a rated current of 25A, a C-curve tripping profile, and a 30mA leakage sensitivity, it is ideal for protecting heavy-duty single-phase circuits and ensuring user safety against electric shocks. Designed for AC-type residual current faults, the device offers a high fault breaking capacity of 6kA and operates reliably at 50/60Hz. It complies with IEC 61009-1 and uses thermal-magnetic tripping combined with fast residual current detection—providing comprehensive protection for both people and equipment.
