Product Overview
Simplify your panel building while elevating human safety with the CHNAILE High-Capacity Residual Current Breaker with Overcurrent Protection (RCBO). Engineered to manage extreme single-phase loads up to 63 Amperes (approx. 14kW), this premium device acts as the secure electrical nerve center for high-demand environments. By combining precise short-circuit, thermal overload, and earth-fault protection into one compact DIN-rail footprint, it saves valuable enclosure space. Featuring a dedicated yellow 'Test' button for routine safety diagnostics and built to stringent GB/T 16917.1 standards, this RCBO is the definitive choice for electrical contractors upgrading main switchboards.

1. Integrated 3-in-1 Safety Mechanisms
Life-Saving Leakage Detection: Contains a highly responsive internal smart-core that continuously monitors the balance between live and neutral currents. The moment a ground fault or human electrocution risk is detected, it severs the power instantaneously.
Heavy-Load Thermal Management (63A): The oversized bi-metallic strips are specifically engineered to tolerate the continuous heavy draw of multiple household appliances running simultaneously, preventing nuisance tripping while guarding against genuine cable-melting overloads.
Arc-Fault Neutralization: Employs advanced magnetic trip coils and robust arc chutes to instantly extinguish explosive short-circuit currents up to 6kA, securing the main panel from catastrophic damage.
2. Superior Material & Ergonomic Design
Thermal-Optimized Enclosure: Housed in a premium, fire-retardant polymer casing. Given the massive 63A capacity, the structural design is optimized to effectively dissipate internal heat, ensuring decades of stable operation.
Diagnostic Test Button: Equipped with a prominent yellow 'T' (Test) button on the front fascia. This enables homeowners and facility managers to periodically verify the mechanical and electrical health of the leakage circuit without tools.
Streamlined Panel Integration: By merging MCB and RCD functions, it reduces wiring complexity and saves crucial DIN-rail space, allowing for cleaner, more professional distribution board assemblies.
3. Target Application Scenarios
Due to its massive 63A threshold and integrated leakage defense, this RCBO is heavily specified for:
Residential Main Incomers: Acting as the primary isolating and protective switch for modern villas and smart homes with heavy electrical loads.
Commercial Kitchens & Catering: Providing mandatory earth-leakage protection and high-ampere power for commercial ovens, fryers, and dishwashing stations.
Workshop Distribution Boards: Safeguarding sub-panels that power heavy-duty single-phase machinery, welders, and large air compressors.
Outdoor & Wet Location Sub-Mains: Ensuring strict electrocution prevention for outdoor lighting grids, pool equipment rooms, and agricultural facilities.
4. Global B2B Partnership with CHNAILE Factory
