✅ CHINT 197933 – NB1L-40 RCBO – 1P+N, 16A, C Curve, 300mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 RCBO is a multifunctional protective device designed for enhanced equipment safety and fire prevention. This 1P+N model offers a 16A rated current, a C-type tripping curve, and 300mA earth leakage sensitivity—ideal for moderate load circuits in residential and commercial settings. The RCBO features a short-circuit breaking capacity of 6kA and provides overload, short circuit, and residual current protection in one compact unit. Designed for AC-type leakage detection, it complies with IEC 61009-1 standards and operates at 50/60Hz. The thermal-magnetic tripping mechanism ensures rapid disconnection in the event of a fault.
