NLB3-40 1-Module RCBO
CHNAILE
Product Overview
Designing electrical systems for micro-architectures—such as backyard office pods, pop-up retail kiosks, or modular housing—presents a strict balancing act between panel space, absolute human safety, and manufacturing costs. The CHNAILE Ultra-Slim 1-Module RCBO resolves this trilemma perfectly. It merges a Miniature Circuit Breaker and a Residual Current Device into an exceptionally narrow 18mm housing, freeing up 50% more space in localized distribution boards. Rated at a highly targeted 4500A (4.5kA) short-circuit capacity, it provides the exact level of defense required for end-of-line branch circuits without the unnecessary expense of heavy-duty commercial breakers, maximizing ROI for high-volume modular builders.

Standard Compliance: | IEC/EN 61009-1 |
1. Precision-Tuned Micro-Space Protection
4.5kA Cost-Optimized Arc Suppression: In localized sub-panels deep within a building or pod, the prospective short-circuit fault current is naturally reduced by cable resistance. The 4.5kA breaking capacity is surgically calculated to handle these end-of-line faults safely, preventing panel fires while significantly reducing component procurement costs for OEM pod manufacturers.
Instant 30mA Electrocution Defense: Micro-homes and pods often place occupants in close proximity to electrical outlets and kitchen/bathroom wet zones. The internal micro-leakage detector continuously monitors the live-to-neutral vector. An escape of just 30mA triggers a mechanical severance in under 0.1 seconds, guaranteeing absolute human safety in confined spaces.
1-Module (18mm) Enclosure Compression: By stacking the magnetic trip coil and residual current toroid vertically, this device enables electrical contractors to install comprehensive 1P+N protection in tiny, aesthetically hidden 2-way or 4-way consumer units that seamlessly blend into compact interior designs.
2. Specialized Structural Engineering
Distinctive All-Blue Interface: The matching blue operational toggle and blue monthly 'Test' button provide a cohesive, premium aesthetic inside modern consumer units, while allowing occupants to instantly identify and interact with the critical safety switch.
Low-Heat Thermosetting Armor: Unventilated walls in modular homes trap heat. The housing is molded from an advanced, V0-rated fire-retardant polymer that efficiently dissipates the thermal energy generated by 16A continuous transmission, ensuring the bimetallic calibration remains accurate without nuisance tripping.
Vibration-Resilient DIN Anchor: Pre-fabricated homes are often transported via highway to their final destination. The base features a high-tension bi-stable locking clip, ensuring the breaker remains rigidly anchored to the DIN rail despite severe road vibrations during transit.
3. Target Application Scenarios
Because of its extreme 1-Module miniaturization, 30mA safety rating, and 4.5kA cost-efficiency, this RCBO is exclusively sourced by global OEMs for:
Acoustic Office Pods & Phone Booths: Serving as the mandatory, space-saving main electrical disconnect for soundproof indoor meeting pods requiring dedicated lighting and AC power.
Prefabricated / Modular Homes: Enabling the construction of ultra-compact consumer units hidden inside thin partition walls of factory-built housing.
Glamping Lodges & Eco-Cabins: Providing comprehensive 1P+N life-safety protection for remote luxury camping structures equipped with compact 16A heating and power circuits.
Pop-up Retail & Coffee Kiosks: Acting as the localized safety hub for small, temporary commercial structures demanding rigorous electrical compliance in a tiny footprint.
