✅ CHINT 197945 – NB1L-40 RCBO – 1P+N, 25A, C Curve, 300mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-40 RCBO is a robust and reliable protective device that combines overload, short-circuit, and residual current protection in a single compact unit. This 1P+N model is rated at 25A, features a C-type tripping curve, and provides 300mA sensitivity for enhanced protection against fire risks and insulation faults in sub-distribution boards and HVAC circuits. With a 6kA short-circuit breaking capacity, this AC-type RCBO ensures effective protection in demanding environments. It operates at 50/60Hz and complies with IEC 61009-1. The thermal-magnetic mechanism with integrated leakage detection allows precise response to electrical faults and leakage currents.
