In the solution put forth, an electrical device (1) comprises a hermetically sealed enclosure (2), at least one fuse (4) and other electrical components inside the enclosure (2), as well as a heatsink (5) outside the hermetically sealed enclosure (2). The at least one fuse (4) is connected to the heatsink (5) with heat conducting material (8). The heatsink (5) is adapted to conduct heat from the fuse to outside of the enclosure (2). The heatsink (5) features a channel (6) for a cooling medium for transferring heat from the heatsink (5) by making use of the cooling medium, whereby the heatsink (5) is a medium-cooled heatsink (5).

An inverter assembly includes an integrated coolant coupling port; a fluid connector having a chamfered lip and a fir tree circumferentially aligned with at least one O-ring on an outer body of the fluid connector; and a flexible hose configured to couple the integrated coolant coupling port to the fluid connector.

An integrated inverter assembly with turbulent flow and increased heat transfer includes an integrated coolant coupling port with a ribbed interior surface; a fluid connector having a chamfered lip and a fir tree circumferentially aligned with at least one O-ring on an outer body of the fluid connector; and a baffled hose configured to couple the integrated coolant coupling port with the fluid connector, wherein the baffled hose provides for compliance in a horizontal plane and a vertical plane.

A connector includes a casing, a shield shell that accommodates the casing, a wire arranged in the casing, a connector terminal connected to the wire, a blocking member that blocks current by overcurrent flowing in the wire, stud bolts and nuts for connecting the blocking member and the wire, and heat conductive members. The casing includes casing concave parts, which are recessed toward a casing space part and have filling space parts to be filled with the heat conductive members. The stud bolts are fixed to the casing and include exposed surfaces that are partially exposed to the filling space parts. The heat conductive members are in direct contact with the exposed surfaces and a shell inner surface in a filled state.

A fuse holder provides a safe device for connecting fuses to a three-phase busbar device. Each phase includes a corresponding load conductor and line conductor mounted within a housing. A mechanical lock is provided for each phase that locks a knife of the fuse to one of the conductors for the phase. In a further aspect, the fuse knives are frictionally locked within the housing. In both the mechanical lock and frictional lock, a release mechanism is provided that can be activated by a screwdriver to release the fuse knives from the fuse holder. In another aspect, certain conductors are provided with heat dissipation wings that contact the housing to dissipate heat generated by current flowing through the conductor.
