摘要： An arc quenching device for a circuit breaker having a stationary contact member and a moving contact member includes a magnetic element formed of an arc quenching core and a base plate. The arc quenching core includes a back wall, and two side walls extending from lateral sides of the back wall. The base plate extends substantially perpendicularly from a lower side of the back wall in a direction as in the side walls, and is fixed to the stationary contact member. The base plate includes a U-shaped magnetic driving core situated near a stationary contact point and extending upwardly from the base plate to surround the stationary contact point, and an arc horn integrally formed with the base plate and obliquely extending toward the back wall from a portion near the stationary contact point. Arc formed between the stationary contact member and the moving contact member is moved by magnetic driving force formed by the magnetic driving core to the arc quenching core to be quenched therein through the arc horn.

摘要： In a movable contactor device in a circuit breaker, two contactor elements are arranged in such a manner that they are in parallel with each other and are independent of each other, to form a movable contactor for each phase. The two contactor elements have respective movable contacts separated from each other, and are rotatably coupled through a supporting shaft to a connecting conductor having three prong-shaped contact pieces. The number of contact points with the stationary contact can be increased as much.

摘要： A circuit breaker is formed of a main body case made of resin and divided into a lower case, an upper cover, and an intermediate case, into which parts of the circuit breaker are integrated. The intermediate case has pocket shaped sockets formed on a top surface side thereof, into which the tips of the interphase partition walls provided in the upper cover are fitted. Also, the intermediate case has recessed grooves formed on a bottom surface side thereof to fit over upper edges of the interphase partition walls provided in the lower case. Thus, the circuit breaker can be assembled easily and becomes more rigid.

摘要： A terminal unit having connection conductors to be connected to corresponding terminals of a switch is installed in a terminal section of the switch, and an external electric wire is connected to each terminal section of the connection conductors. Thus, the insulation distance between phases for the terminal sections and the insulation distance between the terminal section and a panel cut surface are increased according to the requirement of the switch. The shape and size of the terminal unit can be set regardless of the switch, so that a required insulation distance is obtained without increasing the size of the switch main body.

摘要： A bent roundabout current path (8d) rising in the shape of an inverted U is formed between a horn portion (8a) and the end portion of a fixed contact (1) where an arcing horn (8) is joined to the fixed contact (1). An arc (12) is subjected to the electromagnetic force directed to an arc-extinguishing chamber side from the magnetic field H of an current I flowing through the arc-(12)-side conductor portion of the roundabout current path (8d). Therefore, the moving-contact-(4)-side foot of the arc (12) is retained in the leading end portion of the moving contact (4) and not returned to the movable contact (3) side.
