摘要： A fault detector test device includes a test switch including a pivotable lever arm having a first end pivotably connected to rotate about an axis and a second end pivotable in an arc around the axis between an active position and an inactive position. A slide member has a first end accessible by an operator and a second end that cooperates with the second end of the lever arm, the slide member being slideable with respect to the axis of the lever arm such that the second end of the slide member slides in a plane that is substantially tangential to the arc in which the second end of the lever arm pivots. The second end of the slide member and the second end of the lever arm cooperate such that generally planar sliding motion of the slide member is translated into pivoting motion of the lever arm.

摘要： An accessory device for a circuit breaker. The device includes a housing having a top wall and a hinge portion. The device also includes a plunger arm that extends from the hinge portion to form a cantilever wherein the plunger arm includes a first surface and a sloped surface. The plunger arm is moveable between an initial position wherein the plunger arm does not activate the first and second switches located in the housing and a deflected position wherein the first and sloped surfaces simultaneously contact the first and second switches, respectively, thereby activating the first and second switches. The plunger arm also includes a plunger portion that is oriented transverse to the plunger arm. A mating surface is formed on the plunger portion that mates with a mating surface of a circuit breaker operating mechanism. Further, the housing, hinge portion, plunger arm, and plunger portion are integrally formed.

摘要： The disclosed concept pertains generally to secondary terminal blocks and, more particularly, to apparatus and methods for isolating the secondary terminal blocks and associated wiring in electrical switching assembly enclosures. The apparatus includes a housing having an outer surface structured to form a cavity therein. The apparatus is positioned in an enclosure which includes an electrical switching apparatus and one or more secondary terminal blocks. The one or more secondary terminal blocks are positioned in the cavity such that the apparatus at least substantially isolates the one or more secondary terminal blocks from the electrical switching apparatus. Further, the apparatus is effective to substantially isolate the secondary terminal blocks from temperature and pressure effects resulting from an arcing fault occurring in the enclosure.

摘要： A hybrid current switching device has a casing which includes a main current switch having first fixed and movable contacts connected in series with first and second terminals, a power switch device connected in parallel with the main current switch and switchable between an on-state and an off-state, a secondary current switch having second fixed and movable contacts and being connected in series with the power switch device, and a movable-contacts holding shaft on which the first and second movable contacts are mounted. The contacts-holding shaft is positioned inside the casing rotating around a rotation axis to move the movable contacts between a closed position where they are coupled with the corresponding fixed contacts and an open position where they are electrically separated therefrom. The first and second movable contacts are mounted on the rotating shaft with an angular offset relative to each other when in the open position.
