PROBLEM TO BE SOLVED: To provide a circuit breaker device capable of facilitating the operation related to conductive connection and interruption of an electrical circuit or the like.SOLUTION: A circuit breaker device 1 that interrupts an electric circuit by releasing a plug connector 3 inserted into a socket connector 2 from the socket connector 2 comprises a socket main terminal 5 connected to the electric circuit and a socket signal terminal 6 connected to a signal circuit which are provided on the socket connector 2 and a plug main terminal 8 and a plug signal terminal 9 which are provided on a plug connector 3. By inserting the plug connector 3 into the socket connector 2, in a state where the signal circuit is interrupted, the plug main terminal 8 makes contact with the socket main terminal 5 and thereby an electric circuit is conductively connected. By rotating the plug connector 3 while being inserted into the socket connector 2 around an insertion axis line, in a state where the electric circuit is conductively connected, the plug signal terminal 9 makes contact with the socket signal terminal 6 and thereby the signal circuit is conductively connected. |
