PURPOSE: An apparatus for wirelessly controlling a circuit breaker/switch using a public network is provided for decreasing an installation cost based on a wiring work and obtaining an easier maintenance. CONSTITUTION: A sensor unit(24) detects the states(current, voltage, temperature, etc.) of a circuit breaker/switch(12). A data processor(23) processes various information. A wireless communication transmission and receiving unit(22) transmits a processed data value to a center control unit and receives an instruction from the central control unit(11). A switch opening and closing driving unit(25) directly controls the circuit breaker/switch(12). The sensor unit(24) includes detection sensors with respect to the operation state of the circuit breaker/switch(12).
