摘要： A low-exhaust composite drop-out assembly (10) is provided that is utilizable in a standard cutout mounting (12) in electrical power distribution systems. The composite drop-out assembly (10) includes current-limiting (16) and low-current clearing (14) sections and is easily removable from the mounting (12) for servicing. The sections (16,14) are efficiently arranged in a side by side configuration. The low-current clearing section (14) includes a fuse-tube assembly (15) having a replaceable fuse cartridge (52). Accordingly, the low-current clearing section (14) is simply and economically renewable for reuse whether or not the current-limiting section (16) has operated. Further, the current-limiting section (16) need not be replaced if only the low-current clearing section (14) operated in response to overcurrent in a low range. Additionally, the sections (14,16) include separable provisions so that the separable portions of the low-current clearing section (14) can be reused after simple refusing even when the current-limiting section (16) has operated.

摘要： An energy-absorbing element (51) is provided between an insulative piston (52) and a movable contact (28) of a switch (22) for a high-voltage device (12). In arrangements where a fusible element (18) is in electrical shunt with the switch, the energy-absorbing element improves the rapid commutation of the current from the switch to the fusible element where final circuit interruption takes place. The switch is of the general type in which ignition of a power cartridge (32) moves the insulative piston, which is normally located in a bore (30) formed in a conductive member (24), away therefrom and into a passageway (44) formed in an insulative liner (46). The movement of the piston moves the movable contact through the passageway and away from the conductive member to break an electrical interconnection (via 50) between the conductive member and the movable contact. This forms a gap between the conductive member and the movable contact and opens the switch. The ignition of the power cartridge evolves high pressure within a chamber defined by the piston and the bore. This high pressure acts against the piston and the resulting forces rapidly drive the piston; the movable contact being driven via the transmission of forces through the energy-absorbing element. The energy-absorbing element enhances the rapid and simultaneous movement of the piston and the movable contact. The energy-absorbing element absorbs sufficient energy at the interface between the piston and the movable contact to prevent undesirable reaction effects which may be caused by the reaction or rebounding forces between the piston and the movable contact.

摘要： A support arrangement (10) is provided for an electrical device (12) that is embedded within a support body or housing (14). The support arrangement (10) responds to volumetric changes in the material of the support body (14) during the molding of the support body (14). In a specific arrangement, the support arrangement (10) accurately positions the electrical device (12) with respect to the exterior of the support body (14) and includes provisions (e.g. 16,18) for yieldingly supporting the electrical device.
