Abstract:
An inline fuse holder assembly encloses a fuse assembly including a fuse, and first and second wire connectors at respective first and second longitudinal ends of the fuse assembly. The inline fuse holder assembly includes first and second components including respective first and second connectors. The first and second connectors include mateable, non-releasable connection components configured to connect the first and second components to one another and form a substantially waterproof, non-releasable connection upon connection. The first and second components together define an enclosure for enclosing an entirety of the fuse assembly when the first and second fuse holder components are connected to one another.
Abstract:
A high current fusible disconnect switch device (50) includes a switch housing (52) configured to receive a pluggable touch-safe fuse module (54), and a dual slide bar actuator assembly (72) for opening and closing switch contacts. The dual slide bar elements are each coupled to bias elements that store and release energy to affect switch opening and closing operations. The switch opening and closing operation is multi-staged wherein only the first slider element (100) is movable in the first stage, and both the first and second slider elements (102) are movable in the second stage, the fusible disconnect switch device can well meet the demands of high current applications.
Abstract:
A panelboard for fusible switching disconnect devices. The panelboard includes a chassis coupled to a mounting enclosure. The mounting enclosure can be used indoors or outdoors. The chassis is configured to receive one or more fusible switching disconnect devices. Each of the fusible switching disconnect devices includes both a fuse and a circuit breaker-like disconnect in a single, relatively compact housing. The compactness of the housing allows the panelboard to provide a higher level of overcurrent interruption in a smaller sized mounting enclosure than conventional panelboards. For example, the panelboard can have an interruption per volume rating of at least about 33 amps per cubic inch, as compared to about 2 amps per cubic inch for most conventional panelboards.
Abstract:
A fusible disconnect switch devices includes dual sets of switch contacts to connect or disconnect a current path through an overcurrent protection fuse with reduced arcing severity. Faster acting and longer contact path switch mechanisms are described providing satisfactory switching of DC circuits without excessive electrical arcing in a reduced physical package size.
Abstract:
Modular fuse block assemblies configurable to accommodate overcurrent protection fuses of different physical sizes. Single and multi-pole blocks may be easily assembled from a reduced number of modular parts than would otherwise be required, with enhanced safety features and improved capability to meet spacing requirements in a multi-pole fuse block.
Abstract:
A compact fusible disconnect switch device having a reduced switch housing size and increased power density is configured to be face mounted to a panel. A fuse cover assembly allows installation and removal of a fuse without having to open the panel. Line-side and load-side terminals are provided on a common side of the housing. In-line mechanical ganging and simultaneous application is provided for combinations of the compact fusible disconnect switch devices.
Abstract:
A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to move the switchable contact to an open position in response to a predetermined electrical condition.
Abstract:
A touch-safe fuse module ( 100 ) includes a built-in slidable handle ( 110 ) movable between extended and retracted positions relating to a housing ( 102 ) of the fuse module. In the extended position, the handle ( 110 ) assists with removal of the fuse from a base housing assembly ( 200 ) by improving mechanical leverage to apply extraction force to the housing( 102 ).Fuse modules having high current ratings may be effectively removed by hand without separately provided tools.
Abstract:
A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to displace the switchable contact, as well as multiple other components in the device, in response to a predetermined electrical condition.
