Smart Circuit Breaker, suitable for circuits with rated working voltage of 230V/400V, AC 50Hz, and rated current up to 80A.

This electrical protection device instantaneously interrupts power supply upon detecting personnel electric shock or leakage current surpassing preset thresholds, effectively safeguarding human lives and ensuring equipment integrity. Featuring dual overload and short-circuit protection mechanisms for electrical circuits, the device additionally enables occasional circuit switching operations within rated operational parameters.

Leveraging IoT communication technologies (WIFI, LoRa, NB-IoT, 4G, RS-485, Bluetooth, Ethernet, etc.), this system enables telecontrol of circuit breakers to execute automated closure/power-on and main switch disconnection/power-off operations. The integrated smart metering system aggregates critical parameters including voltage, current, leakage current, internal temperature, energy consumption, contact status (closed/open), and fault alerts for overload, short-circuit, and leakage conditions. Through advanced data analytics and statistical computations, it facilitates remote energy management and power optimization across multiple application scenarios, establishing intelligent electrical safety protocols.

The solution is extensively deployed in residential, dormitory, municipal infrastructure, street lighting, agricultural facilities, and rental property circuits requiring centralized remote power management.

Wutai smart circuit breaker features an integrated multi-protection architecture encompassing overload/short-circuit prevention, thermal regulation, load/power restriction, voltage/current surveillance, energy metering, and safety-enhanced maintenance switching. Its advanced monitoring suite includes leakage current detection with self-diagnostic verification, adaptive current modulation, ground fault protection, and dual voltage threshold guardianship (over/under voltage protection). Complemented by professional project-tailored solutions, the smart circuit breaker as a unified electrical safeguard system - consolidating nine conventional low-voltage protection devices into a single smart unit.
