YUANKY C40 N7 RCBO is an integrated residual current circuit breaker combining overload, short-circuit, leakage and overvoltage protection functions, engineered for safe AC power distribution across residential, commercial and industrial environments. This 3-pole model is rated at 40A operating current, compatible with 230/400V AC and 50/60Hz frequency, with a standard 30mA residual tripping current specially designed to prevent fatal electric shocks from direct human contact.

Boasting outstanding short-circuit withstand capacity, the RCBO comes with a visible contact position indicator, allowing installers and maintenance staff to quickly check the on/off status of internal contacts for convenient troubleshooting. Its multi-protection design shields electric devices from insulation deterioration and earth leakage faults, while effectively cutting off circuits under overload, short-circuit and abnormal overvoltage conditions. Compared with separately fitted MCB and RCCB, this all-in-one RCBO optimizes cabinet space and simplifies wiring work greatly.

As a versatile protective component, the C40 N7 RCBO covers diversified installation scenarios. In household applications, it is installed inside domestic distribution boards to protect lighting circuits, home appliances and socket power loops. For commercial projects, it is widely equipped in office buildings, shopping malls and retail shops’ centralized power distribution systems. In industrial fields, it serves small processing workshops, factory auxiliary machinery and terminal control cabinets for industrial control circuits.

The product gains steady popularity in America and many other global regions for new electrical construction and old-circuit renovation projects. Featuring reliable performance and integrated safety functions, YUANKY C40 N7 RCBO becomes a cost-effective preferred option for global electrical wholesalers, contractors and system integrators.
