✅ CHINT 198394 – NB1L-63 RCBO – 1P+N, 63A, C Curve, 300mA Sensitivity, 6kA Breaking Capacity Description (English): The CHINT NB1L-63 RCBO is a high-capacity protective device combining overload, short-circuit, and residual current protection in one compact unit. This 1P+N breaker is rated at 63A, features a C-type tripping curve, and offers 300mA sensitivity—making it ideal for fire risk mitigation and insulation fault protection in large single-phase systems. With a breaking capacity of 6kA, the device is designed for AC-type residual current detection and operates at 50/60Hz. Compliant with IEC 61009-1, the RCBO uses a thermal-magnetic trip mechanism and integrated fast-response leakage detection, ensuring safety in demanding electrical environments such as distribution panels and industrial sub-circuits.
