CHNAILE
Product Overview
Modern electrical safety regulations increasingly mandate individual Residual Current Protection (RCBOs) for every single circuit in a home or commercial property. However, upgrading older distribution boards often means running out of physical DIN-rail space. The CHNAILE Ultra-Slim 1-Module RCBO is a masterclass in electrical miniaturization designed to conquer this bottleneck. Engineered to fit a complete 1P+N (Live and Neutral disconnect) architecture into a standard 18mm width, it frees up 50% more space compared to traditional two-module devices. Calibrated specifically for delicate 10-Ampere continuous loads, it offers sophisticated 6000A short-circuit defense and life-saving 30mA earth leakage detection, making it the premier choice for high-end residential retrofits and localized hotel room power management.

1. Miniaturized Precision Protection
Double Panel Capacity (18mm Footprint): By integrating the magnetic trip coil, thermal bimetal, and zero-sequence current transformer into a solitary 18mm shell, electrical contractors can now upgrade 10 individual circuits with dedicated RCBO protection in a small 10-way consumer unit, a feat impossible with traditional bulky switchgear.
10A Delicate Load Calibration: Standard 20A or 32A breakers are too blunt for delicate modern LED arrays and smart-home relays. The 10A (Curve C) thermal-magnetic core is precision-engineered to react swiftly to minor overloads, preventing the melting of thin-gauge lighting wires often found in wall cavities and drop ceilings.
Instant 30mA Life-Saving Trip: Operating flawlessly within its compact frame, the micro-leakage detector continuously balances Live and Neutral currents. A minute 30mA earth escape triggers an immediate 0.1-second mechanical severance, preventing fatal electrocution in damp domestic environments like bathrooms or en-suites.
2. Specialized Structural Engineering
High-Density Heat Dissipation: Packing a 6kA arc extinguishing chamber and leakage electronics into an 18mm casing generates concentrated thermal stress. The CHNAILE shell is molded from an advanced, V0-rated heat-dissipating polymer, ensuring the breaker runs exceptionally cool even when banked tightly adjacent to dozens of other modules.
Color-Coded Circuit Identification: In a crowded distribution board, locating the correct breaker is crucial. The distinct blue operational toggle designates a critical, low-ampere sub-circuit, while the bright yellow 'T' button reminds homeowners to perform their mandatory monthly leakage safety tests.
Bi-Directional Deep Terminals: Despite its slim profile, the top and bottom screw terminals are deeply recessed and reinforced, comfortably accepting and firmly gripping standard insulated copper wiring to prevent vibration-induced loosening.
3. Target Application Scenarios
Because of its extreme 1-Module space-saving design and precise 10A rating, this RCBO is exclusively mandated by elite electrical contractors for:
Legacy Consumer Unit Retrofits: Upgrading old, crowded residential fuse boxes to modern, individually RCBO-protected circuits without the destructive cost of ripping out and installing a larger enclosure.
Luxury Hotel Room Distribution: Acting as the highly compact, localized protection hub hidden inside wardrobe panels or drop-ceilings for individual hotel room lighting and smart-TV circuits.
Modular Kiosks & Tiny Homes: Providing comprehensive 1P+N life-safety and overcurrent protection in extremely confined architectural spaces.
Smart Home Lighting Arrays: Delivering highly sensitive, dedicated isolation for expensive, low-amperage smart LED dimming matrices and home automation servers.
4. Global B2B Partnership with CHNAILE Factory
Factory-Direct Miniaturization Tech: Micro-RCBO manufacturing requires immense technological capabilities. Sourcing directly from our precision assembly lines eliminates trading margins, making massive residential retrofit projects highly profitable for your EPC firm.
