The YCB9NL-40 RCBO by CNC Electric is a modular protection device that integrates the functions of a miniature circuit breaker and a residual current device. It offers comprehensive protection against overload, short-circuit, and earth leakage currents, including direct and indirect contact hazards and fire risks due to insulation faults.
This model is rated at 6A with a Type C tripping curve, suitable for circuits with moderate inductive loads. It operates at 230V AC, 50Hz, and features a 30mA sensitivity for personal protection. The device complies with IEC/EN 61009-1 standards and is certified by CE and EAC.
Its compact 18mm width allows for space-saving installation on DIN rails. It includes a contact position indicator, non-slip ergonomic handle, and supports monthly test routines.
