CQB7ZN-80 Remote Intelligent Small Circuit Breaker
Overview and applications
The CQB7ZN-80 remote intelligent small circuit breaker can be remotely controlled and operated through communication methods such as WIFI and Bluetooth using a PC or mobile device, and can provide real-time feedback on the circuit breaker status to the device. The product integrates TUYA platform chips, which can easily connect to all TUYA systems and provide data interfaces and customized software services.The product is widely used for remote intelligent control in scenarios such as apartments, schools, and municipal factories.The functions of leakage protection, metering, over voltage and under voltage protection can be customized separately.
Standards: IEC/EN 60947-2, EU ROHS environmental protection requirements, Intelligent control circuit breaker technical specification.
