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 has an automatic trip assembly that generates a tripping operation. The automatic trip assembly includes a magnetic yoke, an armature, and a plurality of abutment members. The magnetic yoke has pivot supports providing for a rotatable disposition of a head portion of the armature. The assembly also includes a biasing member having a first portion and a second portion, the first portion abutted against a selected one of the plurality of abutment members, the second portion abutted against the armature and applying a force to the armature in a direction to normally rotationally displace a bottom portion of the armature away from the magnetic yoke, wherein selecting a different one of the plurality of abutment members to be the selected one causes the force to vary.

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.

摘要： A trip actuator assembly is provided for an electrical switching apparatus, such as a circuit breaker. The trip actuator assembly includes a trip actuator with an actuating element, which is movable among unactuated and actuated positions corresponding to separable contacts of the circuit breaker being closeable and tripped opened in response to a trip condition, respectively. The trip actuator is disposed at a mounting portion of a frame. An interface assembly is movably coupled to the frame and includes an interface element disposed between the actuating element of the trip actuator and a portion of the circuit breaker operating mechanism. When the actuating element moves from the unactuated position toward the actuated position, it engages and moves the interface element, thereby moving the operating mechanism to trip open the separable contacts. The frame secures the trip actuator assembly in a desired orientation within a corresponding one of the housing compartments.

摘要： A main valve for an arc chute is formed by a flexible sheet member that is mounted over a gas opening of the arc chamber structure by extensions on arc plates that form guides received in elongated slots in the ends of the flexible sheet member. The force generated by high pressure gas in the arc chamber on the center of the flexible sheet member causes it to bow allowing arc gases to escape laterally as the ends of the flexible sheet member are drawn towards each other. Flaps formed by slits in the flexible sheet member are deflected by lower pressure gas before the flexible sheet member bows outward.

摘要： A trip bar is provided for an electrical switching apparatus, such as a circuit breaker. The circuit breaker includes a housing, an operating mechanism, and a number of accessories installable within the housing. At least one of the accessories has an actuator, such as a stem. The trip bar includes an elongated pivot member having a first end pivotably coupled to the operating mechanism, a second end disposed opposite and distal from the first end, and at least one protrusion extending outwardly from the elongated pivot member between the first and second ends. Such protrusion is actuatable by the stem to pivot the elongated pivot member. A deflecting mechanism, such as a cam surface, is disposed at or about the second end of the elongated pivot member. When such one of the accessories is being installed within the housing, the stem deflects the cam surface to facilitate insertion.
