摘要： An operating mechanism for a circuit breaker includes a cradle having a generally planar body with a first link opening, at least one first link having an elongated body with a cradle opening, and a toggle rivet having a bushing component and a stake component. The bushing component has a hollow, generally cylindrical body with a first end and a second end, the first end having a radial flange extending outwardly. The stake component has an elongated body with a first end and a second end, the first end having a generally flat head and the second end having a distal tip. When assembled, the bushing component extends through the cradle body first link opening and the first link body cradle opening from a first direction, the stake component extends through the cradle body first link opening and the first link body cradle opening from a second direction, the stake component also extending through the hollow bushing component. In this configuration, the stake component distal tip is deformed thereby locking the bushing component and the stake component together.

摘要： An interlock mechanism for preventing a first circuit breaker having a first actuating mechanism and a second circuit breaker having a second actuating mechanism from simultaneously being in a closed condition. The interlock mechanism includes a frame, a sliding bar slideably mounted within the frame, and one or more retaining protrusions extending outwardly from one or more inner edges of the frame. The sliding bar is movable between a first position and a second position. In the first position the sliding bar blocks a path of movement of the first actuating mechanism and in the second position the sliding bar blocks a path of movement of the second actuating mechanism. The one or more retaining protrusions frictionally engage the sliding bar when the sliding bar is in the first position and holds it in place, preferably with a frictional force sufficient to resist the force of gravity and/or vibrations.

摘要： A circuit interrupter including a housing, separable main contacts within the housing, and an operating mechanism within the housing and interconnected with the contacts. A trip mechanism is disposed within the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation. The trip bar assembly includes an attaching structure which interconnects with an accessory trip member. The accessory trip member causes the trip bar assembly to rotate and generate a tripping operation when the accessory trip member is moved in a first direction. The accessory trip member is configured to enable flexing of the accessory trip member in a second direction opposite of the first direction.

摘要： Apparatus is provided for an electrical circuit breaker for preventing the handle thereof from being moved to the OFF position when the electrical contacts of the circuit breaker are welded closed. This apparatus mechanically limits the travel of the operating handle so that it may not be moved to the OFF position when the electrical contacts are closed. This restrictor apparatus as it is called is mechanically connected to, but out of direct contact with the handle arm of the circuit breaker. The mechanical linkage between the operating handle and the contact arm of the circuit breaker includes a projection. During the foregoing condition, the projection will interact with a crossbar assembly for the contact arm of the circuit breaker. If an attempt is made to move the handle to the OFF position while the contacts remain welded closed, the crossbar assembly is oriented with respect to the path of travel of the projection to prevent the projection from movement past the crossbar assembly and thus to prevent movement of the handle to the OFF position. If, however, the contacts are open as an attempt is made to move the handle to the OFF position, the crossbar assembly will become disposed differently relative to the path of travel of the projection such that the projection will freely move past the crossbar assembly thus allowing the handle mechanism to be moved completely to the OFF position.

摘要： Apparatus which is mechanically connected to and out of direct contact of the handle arm of an electrical circuit breaker to prevent the operating lever of the circuit breaker from being moved to the off position when the contacts of the circuit breaker are closed, due to a weldment of the contacts or obstruction of the contact arm carriers. In particular, a two part toggle mechanism is provided for opening and closing contacts in conjuction with the movement of the operating lever. The lower toggle link has a protrusion thereon which abuts against the rotatable crossbar mechanism which carries the contact arm of the moveable contacts if the contacts have not separated as the operating lever is moved from the closed to open position. The abutments, however, will rotate free of the crossbar if the contact arm moves in conjunction with the movement of the crossbar as the lever is moved from the open to closed position.
