Automatic Mini Circuit Breaker 6~63A Smart Electrical 1P 2P 3P 4P Wifi MCB Breaker

The Smart WiFi MCB is a revolutionary advancement in residential and industrial circuit protection. It combines the core short-circuit and overload protection of a traditional Miniature Circuit Breaker with the intelligence of modern IoT connectivity.
Operating on a standard 2.4GHz WiFi network, this breaker allows users to manage their electrical systems via the Tuya Smart or Smart Life app. Whether you are managing a holiday home, a remote industrial pumping station, or a commercial office, this smart MCB provides total control over your power consumption and circuit status from anywhere in the world.

• Remote Switching & Global Control: Instantly toggle power on or off via smartphone. No hub or gateway is required; the device connects directly to your existing WiFi router.

• Real-Time Energy Metering: Integrated sensors track Current (A), Voltage (V), and Power (W). Monitor live usage and view historical energy data to identify high-drain appliances and optimize utility costs.

• Automated Scheduling & Timer Functions: Set precise "Countdown," "Scheduled," or "Circulating" timers to automate water heaters, pool pumps, or outdoor lighting for maximum efficiency.

• Voice Control Integration: Fully compatible with Amazon Alexa and Google Home for hands-free voice commands in smart home ecosystems.

• Multi-User Sharing: Share device control with family members or facility managers with customizable permission levels.

• Mechanical & Manual Override: Includes a physical manual switch for on-site maintenance, ensuring the breaker remains functional even if WiFi connectivity is lost.

1. Remote Property Management: Manage electricity for Airbnb rentals or student housing to prevent energy waste.

2. Industrial Automation: Reset or isolate remote equipment like telecommunication towers or agricultural irrigation pumps without a site visit.

3. Smart Home Energy Saving: Automatically shut off non-essential circuits during peak hours or when the house is unoccupied.

4. EV Charging Safety: Monitor and schedule electric vehicle charging to take advantage of off-peak electricity rates.

• Anti-Interference Design: Built with high-performance electromagnetic components and an internal antenna optimized for the metal-shielded environment of a distribution box.

• Safety Lock Feature: Equipped with an electronic "Child Lock" and a manual safety lock to prevent unauthorized switching during critical maintenance.

• Over-Voltage & Under-Voltage Protection: Customizable alerts and automatic trip thresholds can be set via the app to protect sensitive electronics from grid instability.

• Standard DIN Rail Fit: At a standard modular width, it fits seamlessly into your existing consumer unit alongside traditional non-smart breakers.

Q: Does the breaker still trip automatically if the WiFi is offline?

A: Yes. The mechanical protection (short-circuit and overload trip) is entirely independent of the WiFi chip. Your safety is never compromised by an internet outage.

Q: Can I use this for a 3-phase motor?

A: Yes, our 3P and 4P models are designed specifically for 3-phase industrial and commercial applications, supporting up to 63A per phase.

Q: Is there a subscription fee for the app?

A: No. The Tuya Smart and Smart Life apps are free to use, and all energy monitoring and remote control features are included with the hardware purchase.
