Abstract (en)
A circuit breaker includes a stationary contact shoe including a conductor and a stationary contact attached to the conductor; a movable contact shoe carrying a movable contact, which movable contact is separably arranged with respect to the stationary contact and is attached to the movable contact shoe; a switching mechanism for rotating the movable contact; an arc-extinguishing unit for extinguishing an arc generated upon parting of the stationary contact and the movable contact from each other; and a case for housing these components. In this circuit breaker, the arc-extinguishing unit includes an arc-extinguishing member so as to cover the entire face of the stationary contact shoe, and the arc-extinguishing member includes a molded arc-extinguishing insulating material mainly containing a non-halogenous flame-retardant resin. The circuit breaker can ensure satisfactory flame retardancy, has satisfactory interruption performances such as overload interruption and short-circuit interruption, and can be miniaturized. <IMAGE>
