PROBLEM TO BE SOLVED: To provide a breaker provided with a current measurement function, capable of simplifying a signal line that is used to output a current value to the outside, and to provide a distribution board using the breaker.SOLUTION: A breaker provided with a current sensor 1 inside a housing 10, and in the breaker, a connector 21 of a signal line of the current sensor 1 is provided nearer the power source side from a handle 11. In the current sensor 1, a pair of arm parts projects from one end of a substrate, and the end portion is opened inside the arm parts to prepare a wire insertion portion, and there is a structure in which a magnetic sensing element is arranged in each of the arm parts. It is preferable that the signal line is a bus cable 20, and the bus cable 20 is wired along a main bar for each of the breakers. |
