摘要： A low-exhaust composite drop-out assembly is provided that is utilizable in a standard cutout mounting in electrical power distribution systems. The composite drop-out assembly includes current-limiting and low-current clearing sections and is easily removable from mounting for servicing. The sections are efficiently arranged in a side by side configuration.. The low-current clearing section includes a fuse-robe assembly having a replaceable fuse cartridge. Accordingly, the low-current clearing section is simply and economically renewable for reuse whether or not the current-limiting section has operated. Further, the current-limiting section need not be replaced if only the low-current clearing section operated in response to overcurrent in a low range. Additionally, the sections are separable so that the low-current clearing section can be reused after simple refusing even when the current-limiting section has operated.

摘要： An improvement in an exhaust device to absorb the energy of exhaust gases released during operation of a circuit interrupting device such as a power fuse or an expulsion fuse is disclosed. The exhaust control device includes a hollow housing coated with a corrosion resistant coating mounted to the circuit interrupting device by means of an adapter, composed of a corrosion resistant material such as brass, which is retained in a counterbore within the housing by rolling or folding over the extended upper rim of the housing so that the coating is not damaged. Alternatively, a steel header, welded to and plated along with the steel housing shell, within which the threaded brass adapter is installed, may also be used. The same rolling or folding operation may be used to secure a plated outlet end wall. Baffles positioned within the housing for partitioning the housing into chambers for cooling and filtering the hot exhaust gases, for changing the direction of flow of the gases and for attenuating sound are held in place by crimping the hollow housing around the baffles so that the plating is not damaged. An annular expansion space formed between the hollow housing and an inner cylindrical shell increases the surface area of the hollow housing which is exposed to the blast of exhaust gases emitted from the fuse and provides an additional expansion chamber for receiving the exhaust gases produced by the interrupting device. A labyrinth plate with circumferential notches formed therein and arcuate ridges formed within and adjacent to said notches, forms gas diverting channels and a labyrinth flow pattern exhaust path to the exit ports formed within an outlet end wall.

摘要： A support arrangement is provided for an electrical device that is embedded within a support body or housing. The support arrangement responds to volumetric changes in the material of the support body during the molding of the support body. In a specific arrangement, the support arrangement accurately positions the electrical device with respect to the exterior of the support body and includes provisions for yieldingly supporting the electrical device.

摘要： A contact arrangement is provided, e.g. of the type that functions as a wiping contact for a moving contact such as a pivotally mounted switch blade in an electrical power distribution switch. The contact arrangement in an illustrative embodiment includes spaced apart contact members that are biased toward each other to define predetermined contact pressure/force characteristics with respect to the interposed moving contact. The contact members in a preferred embodiment include predetermined contact areas and predetermined structural features to minimize deformation due to magnetic forces experienced in the presence of high currents. The structural features are also arranged to define current paths that increase the contact pressure. In a particular embodiment the contact areas are formed on the contact members so as to minimize the size of the moving contact.
