MGB Series Intelligent Circuit Breaker
• Intelligent cloud control (GPRS, Ethernet, WIFI) circuit breaker is developed by our company on the basis of the
• Technical Specification for External Circuit Breaker (State Grid Corporation of China Q/ GDW11421-2005), Technical
• specification for External Low-Voltage Circuit Breaker (China Southern Power Grid), and Technical Specification for
• External Circuit Breaker (CQC1121-2016). The product consists of one miniature circuit breaker with short-circuit
• overload protection and one small intelligent electric operating mechanism which is equipped with one microprocessor and two modules (GPRS, Internet , WIFI). The command would be sent and the data will be received by
• phones, computers and other terminals. GPRS, Ethernet and WIFI would receive the remote controlled command,
• control the tripping or closing of the circuit breaker and feed back the status of the circuit breaker.
