Fuse load-break switch (1) for low-voltage high-power fuses, a fuse contact pair for receiving a fuse (5A, 5B, 5C) being provided within a housing (2) of the fuse load-break switch (1) for each current phase to be disconnected, characterized in that a thermal power loss brought about by the fuses (5A, 5B, 5C) is dissipated into at least one heat dissipation duct (3) provided laterally on the housing (2) of the fuse load-break switch (1).

Implants or sensors often include and rely on inductive and ferromagnetic electrical components to measure and communicate data outside of the body to an external device, creating a safety concern when a patient with these implants or sensors must undergo an MRI scan. Further, various external devices that include inductive and ferromagnetic electrical components are exposed to potentially damaging MRI scans. An electrical coil assembly can include an electrical coil that includes a substrate and an electrical conductor supported by a first face of the substrate. In an example, the electrical coil assembly further includes a fuse element that is configured to move from a disengaged position in which the electrical fuse conductor is out of contact with the electrical conductor to an engaged position in which the electrical fuse conductor contacts the electrical conductor so as to define a short circuit.

A fuse cutout insulator for use in power distribution systems includes three electrically conductive pieces spaced apart and encapsulated by a dielectric material. The conductive components include a top hood, bottom pin, and central pin. The central pin is generally tube shaped and includes an outwardly extending flange to facilitate attachment of the fuse cutout to a utility pole. The top hood and bottom hinge include the traditional components for operable holding of a fuse tube member. The top hood and bottom hinge are accepted in opposite ends of the central pins bore and sealed in spaced relationship during manufacturing by the dielectric material added for fabricating the weathersheds.
