A fuse unit includes: a fusible link which is connected to a battery terminal and of which a fuse is fused when overcurrent flows therein; and a holding mechanism including a base portion that is interposed between a post-standing surface and the battery terminal in a state in which the battery terminal is fastened to a battery post provided on the post-standing surface of a battery housing, and a holding portion that is connected to the base portion and holds the fusible link on the post-standing surface. Accordingly, a load acting on the battery post can be suppressed.

A fuse structure may include an anode pattern, a cathode pattern and a connection member. The anode pattern may be formed on a semiconductor substrate. The cathode pattern may be formed on the anode pattern. The connection member may be electrically connected between the anode pattern and the cathode pattern. The connection member may have different widths.

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.
