    • A circuit breaker having stationary and movable contacts operable between open and closed positions with the movable contact being biased in an open position. The movable contact is mounted to a contact holder which engages one link in a toggle means. The first link is connected to a second link which has a drive pin secured thereto, and the second link is pivotally connected to a toggle lever. A cam is secured to a rotatable drive shaft, and the cam engages a cam roller which is secured to a follower plate. The follower plate has a drive pawl attached thereto, with the drive pawl being disposed adjacent the drive pin. Spring means are pivotally connected to the follower plate and are capable of being in spring charged and discharged positions. The spring is charged by rotation of the drive shaft and cam causing the cam roller to move outwardly. The outward movement of the cam roller causes rotation of the follower plate, resulting in charging of the spring means. When the spring means discharges, it causes rotation of the follower plate such that the drive pawl is capable of engaging the drive pin to move the toggle means into toggle position. Upon moving into toggle position, the toggle means moves the contact holder and movable contact into closed position. Also included are releaseable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively. Means for rotating the drive shaft include a handle secured to the drive shaft and a motor operator having a rotatable output shaft which is capable of engaging the drive shaft and which can be easily installed. A motor and handle clutch is used to prevent rotation of the handle upon rotation of the motor, and to prevent rotation of the motor upon rotation of the handle.
    • 一种断路器,具有固定和可动触点,其可在打开位置和闭合位置之间操作,其中可动触点被偏置在打开位置。 活动触点安装到接触保持器,该接触保持器接合肘节装置中的一个链节。 第一连杆连接到具有固定到其上的驱动销的第二连杆,并且第二连杆枢转地连接到肘节杆。 凸轮被固定到可旋转的驱动轴上,并且凸轮接合固定到从动板的凸轮辊。 随动板具有附接到其上的驱动爪,驱动爪邻近驱动销设置。 弹簧装置枢转地连接到从动板并且能够处于弹簧充放电位置。 弹簧通过驱动轴和凸轮的旋转而带动凸轮滚筒向外移动。 凸轮辊的向外运动导致从动板的旋转,导致弹簧装置的充电。 当弹簧意味着排出时,它引起从动板的旋转,使得驱动爪能够接合驱动销以将肘节装置移动到肘节位置。 在移动到肘节位置时,肘节装置将触点支架和可动触点移动到闭合位置。 还包括可释放的肘节和驱动闩锁装置,用于将肘节装置分别保持在肘节位置并且从动板处于弹簧充电位置。 用于旋转驱动轴的装置包括固定到驱动轴的手柄和具有能够接合驱动轴并且可以容易地安装的可旋转输出轴的马达操作器。 电动机和手柄离合器用于在电动机旋转时防止手柄旋转,并且防止电动机在手柄转动时的旋转。

    • A circuit breaker including first and second spaced-apart stationary contacts and a movable contact operable between open and closed positions with respect to the stationary contact wherein the movable contact, when in the closed position, conducts electricity between the stationary contacts and wherein the movable contact, when in the open position, is spaced apart from one of the stationary contacts. The movable contact has a longitudinal slot extending from one end thereof, and the movable contact is pivotally engaged to one of the stationary contacts at the movable contact end wherein the slot is located. The first stationary contact has an end portion thereof which is disposed within the movable contact slot. Also included is a mechanism for effecting movement of the movable contact between the open and closed positions and magnetic repulsion and magnetic attraction elements for increasing the contact pressure between the stationary and movable contacts.

    • A circuit breaker including a stationary contact and a plurality of movable contacts operable between open and closed positions with respect to the stationary contact. A contact carrier engages the movable contacts, and holds them such that the movable contacts operate together between the open and closed positions. A crossbar and spring holder is secured to the contact carrier and has an aperture therethrough through which is disposed a cross arm. The cross arm extends outwardly from the crossbar and spring holder, and moves upon movement of the crossbar and spring holder, the contact carrier and the movable contacts. Also included is an operating mechanism engaging the cross arm for effecting relative movement of the cross arm to move the movable contacts between the open and closed positions.
