    A 2-pole (L+N) smart circuit breaker combining MCB / RCCB / RCBO functions, enabling remote control, monitoring, and automatic reclosing of the electrical circuit via WiFi connection. This device operates as a circuit breaker with residual current protection and an Auto-Recloser function, which automatically restores power after a temporary fault. Thanks to 2.4 GHz WiFi connectivity, it is suitable for smart homes, commercial facilities, and professional electrical automation.

    Functions

    Remote ON/OFF – electrical circuit control via WiFi without physical access.
    Residual current protection (RCD) – protects people and equipment from leakage current hazards.
    Overcurrent protection (MCB) – automatic disconnection in case of overload or short circuit.
    Auto-Recloser function – automatic power restoration after a temporary fault.
    2-pole (L+N) disconnection – complete and safe circuit isolation.

    Applications

    For home users: Smart home electrical safety, automatic power restoration after short interruptions, remote control of circuits.
    For electricians: Fast DIN rail installation, one device instead of several (MCB + RCD), modern solution for customers.
    For engineers / automation specialists: Smart electrical protection management, remote monitoring, suitable for BMS and smart buildings.
    For commercial and technical facilities: Increased power supply reliability, automatic protection and restoration, reduced downtime risk.
