Scope of Application
The QKB3E-80W Residual Current Circuit Breaker (IoT Intelligent) integrates next-generation IoT communication technology to achieve intelligent protection, connection, and disconnection of circuits. It connects user-side data—including voltage, current, leakage current, temperature, energy metering, and fault alarms—to smart electricity systems. Through remote control, real-time alerts, statistical analysis, energy services, energy management, and big data analytics, it enables intelligent electricity safety management across various application scenarios.
It is widely used for smart electricity applications in homes, dormitories, municipal projects, street lighting, farms, rental properties, and other electricity consumption sites. Complies with GB/T 16917.1 standard.
