摘要： A rotary contact circuit breaker employs a crank to couple a switching mechanism to the rotary contact pole structure. The use of a crank allows for the mechanism and pole structure the individually optimized without effecting the performance of the other. In particular the crank allows for a mechanism that is able to achieve maximum torque delivery to the pole structure.

摘要： A draw out interlock mechanism comprises a draw out trip arm pivotally attached in a draw out circuit breaker and an interlock activating assembly attached to a the draw out circuit breaker. The draw out trip arm comprises a first extension on a first end and a second extension on a second end. The first extension is positioned to interact with a trip latch of the operating mechanism. The interlock activating assembly comprises an extended arm and a camming arm, which are pivotally attached to a pin supported by a mounting bracket attached to the draw out circuit breaker. The extended arm extends through an aperture in the draw out circuit breaker with an end thereof proximate to the second extension of the draw out trip arm. The camming arm is adapted to interact with a camming surface attached to the draw out circuit breaker compartment such that when the draw out circuit breaker is inserted into the compartment, the camming arm and the extended arm rotate independently clockwise, the extended arm interacting with the draw out trip arm causing the draw out trip arm to rotate in counterclockwise, which in turn causes the first extension of the draw out trip arm to interact with the trip latch causing the draw out circuit breaker to trip, opening the contacts in the draw out circuit breaker.

摘要： An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure. The spacers and protrusions serve to widen the stances of the operating mechanism for force distribution purposes, and also to minimize friction between movable components.

摘要： The circuit breaker is characterized by separable contacts operable between a closed and an open position a contact arm having a latching surface and a latch arranged to engage the latching surface when the contacts are blown-open under short-circuit conditions. The arrangement of the latch allows for a positive lock under high magnitude short circuit levels while minimizing the force required by a mechanism to unlock the arm.
