An electrical fuse includes a housing, first and second terminal assemblies coupled to the housing, and at least one fuse element assembly extending internally in the housing and coupled between the first and second terminal assemblies. A filler surrounds the at least one fuse element assembly, and the filler includes sodium silicate sand and at least one reinforcing structure suspended within the filler.

An embodiment of an arc flash reduction maintenance system includes a pyrotechnic disconnect module and an overcurrent protection device connected to the pyrotechnic disconnect module. A control line is connected to the at least one pyrotechnic disconnect module and in parallel with one of the pyrotechnic disconnect module and the overcurrent protection device. The control line provides a self-generating control signal to cause the pyrotechnic disconnect module to electrically isolate the overcurrent protection device. A switch is located in the control line to selectively enable or disable at least one arc flash reduction maintenance system mode in the control line.

Arc flash reduction maintenance system with pyrotechnic circuit protection modules

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.

Low profile fusible disconnect switch device

Fuse assemblies, systems and methods of manufacture include reinforcement materials and arc absorbent materials to provide overcurrent protection for 1500 VDC power systems without enlarging the body of the fuse.

High voltage, reinforced in-line fuse assembly, systems, and methods of manufacture

A pyrotechnic circuit protection system includes a first connection terminal, a second connection terminal and a plurality of pyrotechnic modules connected between the first and second connection terminals. Each of the pyrotechnic modules includes a nonconductive housing and electrical connectors facilitating plug-in connection of the pyrotechnic modules to one another. A single control module may control and coordinate a plurality of pyrotechnic disconnect modules.

Pyrotechnic circuit protection systems, modules, and methods

Modular circuit protection systems and methods

An embodiment of a fuse module has been disclosed. The fuse module includes a housing and a fuse element assembly contained within the housing. The fuse element assembly includes at least one fuse element unit having a plurality of trigger mechanisms and a perforated strip electrically connected to the trigger mechanisms. Increased ampacity ratings in a more compact arrangement provides for fuse modules having increased current protection capability that, in turn, provides for improved disconnect switching capabilities.

Compact dual element fuse unit, module and fusible disconnect switch

A fuse block assembly includes a nonconductive base formed with pedestal surfaces attachable to terminals from a location above the base, while providing a clearance between the body of a fuse and the middle portion of the base when a fuse is installed.

Compact modular fuse block with integrated fuse clearance

An embodiment of a fuse module has been disclosed. The fuse module includes a housing, a fuse element unit disposed within the housing, and a pair of terminal blades between which the fuse element unit is electrically connected. Each terminal blade has a pair of connection portions.

Fuse module and fusible disconnect switch assembly therefor

An embodiment of a power distribution system has been disclosed. The power distribution system includes a fuse holder having a plurality of line-side terminals. The power distribution system also includes a bus module having an enclosure and a conductor disposed within the enclosure. The conductor includes a comb-type bus bar having a base member and a plurality of branch members extending from the base member and each embodying a terminal connectable to one of the line-side terminals of the fuse holder.

Fuse holder and configurable bus module for power distribution system

A modular fuse holder includes a cover that is movable from a closed position to an open position relative to a base along two different paths of motion to prevent inadvertent opening or closing of the cover.

Modular open fuse holder with multi-stage positionable cover

A fuse holder includes a two piece base assembly allowing assembly and attachment of fuse clips and terminals without separately provided, external fasteners such as screws. Fuse rejection features may be built-in to the base assembly adjacent one of the fuse clips.

Modular open fuse holder

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.
