CQB7ZN-80 Remote Intelligent Small Circuit Breaker

The CQB7ZN-80 series smart remote circuit breaker is designed by CHAC Electric for use in AC 50Hz systems with a rated voltage of 230/400V and a rated current up to 80A. It provides overload and short-circuit protection while functioning as an intelligent reclosing circuit breaker. The breaker offers global remote control via mobile phone for switching the circuit on/off, timed operation, delayed activation, and cyclic switching, with manual operation status feedback to the mobile phone. It also optionally includes energy metering functionality. This product meets standards such as IEC 60898-1, GB/T10963.1, and technical specifications for smart control circuit breakers. Our CQB7ZN-80 series ensures reliable and efficient operation, providing a robust solution for remote intelligent control of various scenarios and equipment.
