Abstract:
A small circuit breaker which effectively provides interception for overload protection and short-circuit protection while exhibiting outstanding flame retardancy. The circuit breaker comprises a fixed contact member or conductor carrying a fixed contact, a movable contact member carrying a movable contact for engagement with the fixed contact, a switch mechanism for rotating the movable contact member, an arc-extinguishing device for extinguishing an arc when the movable contact is engaged or disengaged with the fixed contact, and a housing for enclosing the components described above. The arc-extinguishing device is provided with an arc-extinguishing member that entirely covers the fixed contact member. The arc-extinguishing member includes an arc-extinguishing mold of insulator with a base material of frame-retardant non-halogen resin.
