The LRR6 1P ZigBee Smart MCB is a high-performance IoT-enabled electrical distribution device, purpose-built for smart building automation, safe power management, and energy efficiency optimization across residential, commercial, industrial, and public infrastructure projects. As a Tuya-compatible ZigBee smart circuit breaker, it integrates manual & automatic dual control, unlimited remote switching, customizable protection, and auto reclosing functions, fully compliant with IEC: 60898 international standards. Designed for system integrators, electrical contractors, real estate developers, facility management teams, and wholesale distributors, this DIN-rail mount smart MCB delivers scalable, reliable, and cost-effective smart power control for large-scale deployments and custom project requirements.
This smart MCB supports Tuya APP, Mi Home, ZigBee, WiFi, RS485, dry contact, and wireless kinetic energy protocols. It eliminates extra development costs for system integrators, enabling seamless docking with existing building management systems (BMS), and fully adapts to diverse project specifications across different industries.
Equipped with integrated manual/auto operation modes, unlimited-range remote on/off, timed switching, and linked control functions. This feature drastically reduces on-site manual operation and labor costs for facility management teams, enabling centralized control of multi-site projects — such as timed lighting for public commercial areas, remote power management for rental housing, and automated equipment scheduling for industrial sites.
Built-in over-voltage, overload, short circuit, and leakage protection, with a tripping time ≤0.1S and short circuit response time ≤0.04S, plus 6KA breaking capacity. Fully compliant with global electrical safety standards, it supports fully customizable protection thresholds to meet the unique safety specifications of different projects, minimizing electrical safety accidents and liability risks for project contractors and operators.
Supports auto reclosing with fully customizable time settings. This function reduces on-site maintenance trips and operational costs for unattended scenarios such as streetlights, base stations, farms, and greenhouses, improving system uptime and reducing long-term O&M pressure for infrastructure operators.
1P core specification with standard DIN rail mounting, with optional rated current ranging from 10A to 63A, and Type C/D trip curves available. It fits standard distribution boxes without modifying existing wiring, greatly reducing installation time and labor costs for bulk project deployment and retrofit projects.
Wide operating temperature range from -20℃ to +70℃, altitude limit ≤3000m, IP20 rating, and standby power consumption <3W. It ensures stable, reliable operation in industrial, outdoor, and complex environmental conditions, reducing after-sales maintenance costs for long-term project operation.

Ensure the upstream power supply is fully disconnected before installation, and verify the device’s rated voltage and current match the project’s electrical system requirements. All installation work must be performed by a certified electrician to comply with local electrical safety regulations.
Mount the device on a standard 35mm DIN rail in the distribution box, ensuring secure fixation.
Connect the upper terminal of the MCB to the mains power supply, and the lower terminal to the load, following the product wiring diagram.
Confirm all wiring connections are tight and secure, with no loose terminals or exposed conductors.
Download the Tuya APP on your mobile device, register an account, and log in.
Power on the device, wait 10 seconds, then press and hold the pairing button until the indicator light starts flashing, confirming the device has entered pairing mode.
In the Tuya APP, click the "+" icon in the top right corner to enter the device adding interface, and wait for the app to detect the device automatically.
