ABSTRACT:
In a circuit breaker includes a fixed contactor, a moving contactor subjected to a switching operation of a switching mechanism, a heater connected to the moving contactor and disposed in such a manner as to extend along a fixed core and a moving core pivotally supported by the fixed core, the fixed contactor is formed in a J-shape and is interposed between an insulating member disposed on the fixed contactor in such a manner as to extend along the side of the fixed contactor facing the moving contactor and a demagnetizing member disposed in such a manner as to extend along the bent inner surface. The circuit breaker includes also an operation time adjusting mechanism engaging with the moving core and capable of adjusting the operation time of the moving core, and a casing storing therein the constituent elements. The operation time adjusting mechanism is brought into abutment against an adjustment portion formed on the moving core, and is detachably mounted on the casing.
