PROBLEM TO BE SOLVED: To provide a circuit breaker with good assemblability and a good appearance without pinching an output signal lead wire of a CT due to a case of the circuit breaker and a cover of a distribution board.SOLUTION: In a circuit breaker 1, a current transformer (CT) is mounted to a main circuit conductor section arranged in a unit body, and a CT output signal lead wire 110 transmitting output signals of the CT is led to the outside of the unit body, so that the output signals of the CT can be transmitted to the outside. The unit body is constituted by overlaying a first case 101 and a second case 102 from both sides in a width direction of the circuit breaker. A slit reaching a side wall of one case from a face overlaid on the other case is formed on one case, and the CT output signal lead wire 110 is led to the outside of the unit body from the slit. |
