PROBLEM TO BE SOLVED: To provide a plug-in circuit breaker capable of easily implementing connection work when connecting in parallel a plurality of terminal blocks to an attachment device disposed within a board.SOLUTION: Each of plug-in circuit breakers 2A, 2B and 2C includes a terminal block 20 and a circuit breaker body 21 including external connection terminals 23a, 23b, 24a and 24b and a plurality of plug-in circuit breakers 2A, 2B and 2C are arranged side by side on a distribution board 1 and connected to an attachment device 7. In the terminal block, first and second attachment side connection parts 30b and 31b are formed while being separated from each other in a direction orthogonal to a direction of arrangement, and a first wiring space 36 and a second wiring space 39 are formed which linearly extend to both ends in the arrangement direction of the terminal blocks. In the plurality of terminal blocks which are disposed side by side, the first wiring spaces of the terminal blocks are linearly continued, the second wiring spaces of the terminal blocks are linearly continued, and a first linear wiring member 40 and a second linear wiring member 41 are disposed in the wiring spaces. |
