摘要： A charging handle assembly for charging the closing springs of a stored energy mechanism which closes the contacts of a circuit breaker. The charging handle has a generally U-shape and is pivotally attached to the circuit breaker cover. The handle is adapted to cooperate with the stored energy mechanism such that the cover and handle are easily removed from the circuit breaker. Additionally, the handle cooperates with the cover and the stored energy mechanism so that energy is transferred to the springs of the mechanism by pumpiing the handle.

摘要： A plug-in trip unit joint 900 for a molded case circuit breaker 10, with the circuit breaker 10 having an operating mechanism 40 with a movable contact arm 45 mounted on a cross-bar 55, a trip bar 618 and a line terminal mounted in a first housing and a trip unit 600 and a load terminal 16 mounted in a second housing. The plug-in trip unit joint 900 comprises a trip unit stab 910 coupled to the trip unit 600 and load terminal 16 and extends from the second housing and a movable contact arm clamp assembly 909 mounted in the first housing and aligned to selectively engage the trip unit stab 910 wherein the line terminal 18 and the load terminal 16 are electrically coupled together and with the trip unit in selective contact with the operating mechanism 40 of the circuit breaker 10. The movable contact arm clamp assembly 909 comprises a pair of connectors 916, 918 with one connector 916 positioned along one side of the movable contact arm 45 and one connector 918 positioned on a corresponding opposite side of the movable contact arm 45. Each connector 916, 918 has a first end 930 and a second end 932 with the first end 930 configured to engage one side of the movable contact arm 45 and the second end 932 configured to engage one side of the trip unit stab 910. A biasing member 920 positioned to engage both connectors between the first and second ends 930, 932 of each connector 916 is installed to urge both connectors 916, 918 against the movable contact arm 45 and the trip unit stab 910 and establishes an electrical and mechanical coupling. The contactors sandwich the contact arm 45 and the trip unit stab 910 between them and is held together with a U-shaped spring. In one embodiment, each end of the connector 916 includes a spherical surface for engagement with the movable contact arm 45 and the trip unit stab 910.

摘要： A mechanism for accumulating and storing mechanical energy, wherein the energy is used to close the primary contacts of a circuit breaker. The energy can be input to the mechanism manually or by means of a motor. The mechanism includes a series of linkages which function to utilize the energy to close the primary contacts. These linkages also function to maintain the closing force upon the primary contacts, while also functioning to allow rapid contact opening when desired.
