摘要： 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.

摘要： A circuit interrupter including a releasable latch restrained by a stamped metal rotatable cam having a latching surface in sliding contact with the latch member. The rotatable cam is inclined at an angle to the axis of rotation so as to cause only the smooth portion of the latching surface produced by the shearing action of the stamping process to contact the latch member. The rough portion of the latching surface produced by tearing action of the stamping process is not in contact with the latch member, thereby eliminating the need for a machining operation to provide a low friction contact surface with the latch member.

摘要： 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.

摘要： 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.
