A cube fuse adapter (1) comprising an adapter housing (2) shaped in the form of a cube fuse and including a pair of fuse reception contacts (4-1, 4-2) provided to receive a cylindrical fuse (5), wherein both fuse reception contacts (4-1, 4-2) are connected to associated electrical contacts (3-1, 3-2) protruding from a bottom side of the adapter housing (2) of said cube fuse adapter (1).

A high-voltage fusing apparatus includes a current fuse, a temperature fuse, and a current-carrying fuse. The current fuse is connected in series with the temperature fuse, and a series branch of the current fuse and the temperature fuse is connected in parallel with the current-carrying fuse. A resistance value of the current-carrying fuse is less than a resistance value of the current fuse, and a fusing temperature of the current-carrying fuse is lower than a fusing temperature of the temperature fuse. The high-voltage fusing apparatus can cut off a high-voltage circuit quickly, and effectively protect the high-voltage heating circuit from overheating.

A fuse holder for holding a fuse is provided that includes a body, a line side connector supported by the body, and a load side connector supported by the body. The fuse holder also includes a toggle switch supported by the body and capable of toggled engagement in a first position that provides electrical connection. The switch is also capable of toggled engagement in a second position that provides electrical isolation between the line side connector and the load side connector. The fuse holder also includes a fuse carrier. The fuse carrier is supported by the body and adapted for holding the fuse and the fuse carrier is adapted to be removed from the fuse holder. The fuse holder includes a blocking device blocking the toggled engagement of the switch from the second position to the first position when the fuse carrier is not within the fuse holder.
