NLRO-40L 1P RCBO
CHNAILE
Product Overview
Ensure unparalleled electrical safety with the CHNAILE NLRO-40L 1-Pole Plug-in RCBO. Unlike standard MCBs, this unit is engineered to deliver complete protection by integrating overcurrent, short-circuit, and ground fault (earth leakage) detection into a single, compact module. The highly responsive 30mA residual current threshold ensures immediate tripping upon detecting dangerous leakage, effectively safeguarding personnel from fatal electrical shocks. The attached coiled pigtail wires allow for a seamless connection to the panel's neutral/earth bus bars, making installation fast and compliant with modern electrical codes.

Advanced Features & Safety Benefits
3-in-1 Comprehensive Protection: Protects your valuable appliances from overcurrents/short-circuits while simultaneously protecting human lives from earth leakage and electrical shocks.
Pigtail Neutral Design: Features pre-attached pigtail wiring required for plug-in load centers, ensuring the internal leakage-detection circuitry is perfectly powered and referenced.
Integrated Test Button: Equipped with a built-in 'Test' push-button, allowing facility managers and homeowners to periodically verify the health and responsiveness of the earth leakage function.
High 6kA Interruption Rating: Robustly built to withstand and safely extinguish high fault currents, preventing catastrophic panel fires.
Ideal Applications
Because of its 30mA life-saving sensitivity, this Plug-in RCBO is mandatory and highly recommended for:
Wet or damp locations (Bathrooms, Kitchens, Laundry rooms)
Outdoor power outlets and exterior lighting circuits
Commercial building sub-distribution boards
Pool, spa, and hot tub equipment panels
