The YCB9NL-40 RCBO from CNC Electric is a modular DIN rail-mounted protection device that integrates the functions of a miniature circuit breaker and a residual current device. It provides overload, short-circuit, and earth fault protection, making it ideal for residential buildings and moderate-load circuits.
This model is rated at 32A with a Type C tripping curve, suitable for circuits with moderate inductive loads such as lighting systems, fans, and small appliances. It operates at 230V AC, 50Hz, and features a 30mA sensitivity for personal protection against electric shock and fire hazards caused by insulation faults.
The RCBO complies with IEC/EN 61009-1 standards and is certified by CE and EAC. It includes a contact position indicator (red = ON, green = OFF), a non-slip ergonomic handle, and supports monthly test routines. Its 18mm width allows for space-saving installation on DIN rails.
