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. An operating mechanism, for effecting movement of the contacts between the open and closed positions includes a toggle having first and second links and a toggle lever. Also included is a releasable toggle latch for holding the toggle in a toggle position. The toggle latch includes a rod having a flat surface which is adjacent to and contacts, the toggle lever. The rod is rotatable between first and second positions with the rod flat surface, when in the first position, preventing movement of the toggle lever and when in the second position permits movement of the toggle lever such that the toggle can be released from toggle position. A latch catch is fixedly secured to, and rotatable with, the rod, with movement of a latch catch causing movement of the rod. The latch catch is biased in the rod second position where the toggle lever can be released, and a releasable lever system holds for the latch catch in the rod first position.

摘要： A circuit breaker including stationary contact means and a plurality of movable contacts operable between open and closed positions with respect to the stationary contact means. A plurality of contact springs engages the movable contacts, and the contact springs increase the engagement pressure between the stationary contact means and movable contacts when the movable contacts are in the closed position. 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 a plurality of openings therein for holding the contact springs and 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 are means 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 and spring 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, which rotates about an axis different from the drive shaft axis, 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. The degree of rotation of the cam during the charging rotation is more than twice the degree of rotation of the follower plate, thereby gaining a mechanical advantage. 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 releasable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively.

摘要： A circuit breaker having a stationary contact and a movable contact operable between open and closed positions with respect to the stationary contact. The circuit breaker includes means for moving the movable contact between the open and closed positions. These movement effecting means include an opening spring capable of being in two positions; a first position whenever the movable contact is in the open position, and a second position whenever the movable contact is in the closed position. An indicator rod is coupled to the opening spring and indicates the position of the opening spring.
