The NXBLE-63 Residual Current Operated Circuit Breaker (RCBO) combines residual current, overload, and short-circuit protection in one compact unit. Designed for AC 50/60Hz systems up to 240/415V, it ensures reliable personal and equipment safety by detecting earth leakage faults while maintaining circuit continuity. With rated currents from 6A to 63A, B and C tripping curves, and breaking capacity up to 6kA, the NXBLE-63 offers enhanced electrical protection and complies with IEC/EN 61009-1 standards for residential, commercial, and industrial power systems.
