摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing and rotatable between a contact open position and a contact closed position, and an operating mechanism disposed in the housing and interconnected with the contacts for rotating the contacts alternatively between the contact open position and the contact closed position. The operating mechanism includes a handle moveable by an operator between handle open and handle closed positions normally corresponding to and resulting in the contact open position and the contact closed position, with the handle including a protrusion. The operating mechanism further includes a crossbar assembly for rotating with the contacts as the contacts rotate between the contact open position and the contact closed position. The crossbar assembly includes a stop member that is positioned to abut against the protrusion as the handle is moved towards the handle open position when the contacts and the crossbar assembly remain in the contact closed position. The operating mechanism also includes a sideplate assembly having stops that prevent disengagement of the handle.

摘要： A circuit breaker includes a housing having a first insulating portion, a line end, a load end and a pair of separable contacts electrically disposed between the line end and the load end. An operating mechanism includes a second insulating portion and a movable arm carrying one of the separable contacts. The operating mechanism is structured to move the separable contacts between an open position and a closed position. A shunt is electrically interconnected between the movable arm and one of the line and load ends. The first insulating portion is disposed between the separable contacts and a portion of the shunt. The first and second insulating portions cooperate at or about the closed position of the separable contacts to prevent an arc from passing from the separable contacts to the conductor.

摘要： A secondary arc chute is for an electrical switching apparatus including a housing, a pair of separable contacts enclosed within the housing, and a primary arc chute disposed proximate the separable contacts in order to attract an arc generated by the separable contacts. The primary arc chute has a first end including an arc horn, and a second end. The secondary arc chute includes a chute member made from a magnetic material, such as nickel-plated steel, and including a first portion disposed at or about the arc horn of the primary arc chute, and a second portion. The chute member provides an extension of the primary arc chute in order to facilitate drawing the arc away from the separable contacts and to ground the arc into the housing of the electrical switching apparatus.

摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. The operating mechanism includes a cradle for moving from a first position to a second position in the event of a tripping operation and thereby causing the contacts to open. A trip mechanism is disposed in the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation. The trip mechanism includes a rotatable latch that engages the trip bar assembly and the cradle and keeps the cradle in the first position when a tripping operation has not occurred. The trip mechanism further includes a tension member that is positioned to bias the latch in a first rotational direction.

摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. A trip mechanism is disposed in the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation that causes the contacts to open. The trip mechanism further includes an automatic trip assembly for selectively rotating the trip bar assembly upon a predetermined current threshold. The automatic trip assembly includes a magnetic yoke having two arms with a pivot support on the top of each. Each of the pivot supports includes a pivot surface, and one of the pivot supports includes a rear retaining protrusion adjacent its pivot surface. The other of the pivot supports includes a front retaining member adjacent its pivot surface. The automatic trip assembly further includes an armature having pivot portions positioned on the pivot surfaces which provides for rotation of the armature between a first position away from the arms and a second position closer to the arms. A magnetic field is generated upon the predetermined current threshold which causes the armature to rotate from the first position to the second position and to rotate the trip bar assembly. One of the pivot supports also includes a downwardly facing stop. The downwardly facing stop is positioned to abut the armature when the armature is rotated away from the arms, thereby defining the first position.
