A distribution line protection pipe is provided to rapidly cope with an electric leakage by controlling a circuit breaker with a wireless mode. A circuit breaker(100) connects a power line(L) connected to a generation part to a power line(L') connected to an electrical device. The circuit breaker includes a protection case(10), a first connecting bar(20), a second connecting bar(20'), and a blocking member(30). A driving motor is installed in an outer surface of the protection case. A power supply part supplies a power source to the driving motor. A current leakage sensor senses an electric leakage on the power line connected to the electrical device. An input unit inputs a returning signal of the driving motor. A control unit is connected to the driving motor and the current leakage sensor. The control unit receives the returning signal of the driving motor from the input unit. An output unit outputs a control state of the input unit to outside. |
