PROBLEM TO BE SOLVED: To automatically turn off a switch mechanism at abnormality. SOLUTION: A switch mechanism 12 is constituted within a case 11, and also an operation mechanism 13 for turning on or turning off the switch mechanism 12 is constituted. This breaker is provided with a lock mechanism 14 for retaining the switch mechanism 12 in on-state, and a release mechanism 15 for releasing the lock by the lock mechanism 4. The release mechanism 15 is composed of a release operation piece 34 and a solenoid 36, and when a shock signal is outputted from a shock sensor 47, the solenoid 36 operates, and the lock is released. Accordingly, if abnormal state of thing occurs, the lock is released, and the breaker device is automatically turned off. |
