摘要： An improved circuit breaker includes a case, a movable arm, and a bumper retained within a receptacle formed on the case. The bumper is retained in the receptacle by a number of spaced ribs that engage certain portions of the bumper yet permit deformations of other portions of the bumper into an expansion region. By employing a bumper made of a material having a low coefficient of restitution, deformation of the bumper tends to dissipate the energy of a removable arm impacting the bumper. The bumper can be installed, removed, and replaced substantially without requiring the use of an adhesive. The movable arm engages the bumper on a corner of the bumper to provide the bumper with an effectively progressive spring rate.

摘要： A seal apparatus having a seal member and a plurality of fasteners is mounted on an arc hood of a cassette in a switchgear cabinet and resists leakage of arc gases through a gap between the arc hood and a circuit breaker mounted in the switchgear cabinet. The seal member is flexibly received against the circuit breaker in a racked position and is preferably at least nominally deflected thereby to resist the flow of arc gases in a leakage direction through the gap. The seal member thus resists the arc gases from coming into contact with a plurality of line conductors at the rear of the circuit breaker until the arc gases have at least somewhat cooled, deionized, and/or slowed. The seal apparatus thereby resists arc gases from inducing arcing between adjacent line conductors, whereby the circuit breaker can be operated at substantially higher voltages.

摘要： A spring biased anti-rollover cam extends the drop-off point on the drive cams of the spring powered operating mechanism of a power circuit breaker to preclude premature tripping in response to high short circuit currents. The anti-rollover cam retracts to facilitate normal reset of the latch mechanism when the spring of the operating mechanism is recharged for the next closing of the breaker.

摘要： Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided.

摘要： An improved circuit breaker includes an arc extinction system having one or more insulators that generates a desirable gas in the presence of an arc. The exemplary circuit breaker includes gas-generating insulators disposed at three sides of a stationary contact and an arc chute at a fourth side of the stationary contact. The gas promotes the desirable extinction of the arc in a number of exemplary fashions. The presence of the gas on three sides of the stationary contact can resist movement of the arc toward the gas, thereby substantially limiting movement of the arc in a direction other than toward the arc chute. The gas can remove heat from the arc, thereby promoting deionization of the plasma by forming neutral molecular species at a lower temperature state. The presence of the gas can reduce the concentration of ions and electrons within the interior of the circuit breaker and can increase the pressure within the circuit breaker, and these also facilitate extinction of the arc.

摘要： An integral stationary arcing contact and arc runner for electrical switching apparatus is formed by an electrically conductive member secured to the line conductor adjacent the stationary main contact thereby providing a joint free path for the arc to pass from the arcing contact to the arc runner. Preferably, the electrically conductive member is a sheet metal member having a base section secured to the line conductor, an arcing contact section adjacent the stationary main contact and extending generally perpendicular to the line conductor and a runner section extending at an obtuse angle to the arcing contact section toward the arc chute. A support member between the arcing contact section and the housing transmits reaction forces imposed by the moving conductor assembly on the sheet metal member into the housing.

摘要： A contact guide member extends transversely to the contact fingers on the contact carrier of electrical switching apparatus and has spaced openings through which the contact fingers extend and are held in spaced relation. The contact finger guide member is positioned to isolate the arc toes adjacent the free ends of the contact fingers from the main contacts and the contact springs in order to protect the latter items from the arc gases and debris generated during arcing. The openings in the contact finger guide member are elongated to permit differentially pivoting of the contact fingers, but not axial movement. The contact finger guide member slides in a pocket molded in the end face of the contact carrier and is captured by and moves with the contact fingers.

摘要： A mounting bracket for a circuit breaker air-core coil includes a unitary body having a generally U-shaped body. The body has at least one retaining form structured to fit over a fastener head. When installed in a typical power air circuit breaker, the air-core coil disposed in the mounting bracket is located above the circuit breakers's load conductor fasteners. These fasteners, and therefore the air-core coil, are located outside of the space in the circuit breaker occupied by a current sensor.

摘要： A circuit breaker includes a load terminal and a line terminal; a pair of main contacts; a separable pair of arcing contacts; and a moving conductor assembly having a contact carrier mounted for movement between an open position and a closed position to open and close the separable pairs of contacts. The circuit breaker further includes an arc chute and an arc runner electrically connected to a stationary arcing contact and extending toward the arc chute to provide a path for an arc struck between the separable pair of arcing contacts as the separable pair of arcing contacts open with movement of the moving conductor assembly from the closed position. The arc runner has a longitudinal elongated raised ridge generally laterally centered.

摘要： The contact fingers of electrical switching apparatus have radial convex surfaces centered on the pivot pins which seat on concave surfaces in the molded contact carrier to transmit bending loads on the pin into the carrier. A seal member which snaps onto the end of the pivot pin has fins which extend between the contact fingers to block flow of arcing gases through the carrier. For lower current ratings, some of the contact fingers are replaced by annular spacers which also transmit bending moments into the carrier and restrict gas flow. A stop ledge on the carrier against which the contact springs bias the contact fingers has a recess which allows the center fingers to project farther toward the stationary contacts so that the arc toes on these fingers are the last to separate on opening and the arc is concentrated on them. The drive pin connecting the carrier to the operating mechanism has flats which key it for engagement in a slot in the carrier for installation and removal only with the carrier pivots lifted out of their bearing pockets by removal of the rear casing.
