The Bussmann CUBEFuse, the world's first "finger-safe" industrial power fuse, uses an industry-first recessed blade style terminal. The blades are positioned and provided with an extended insulating sleeve to prevent personal contact with any energized component of the CUBEFuse during normal operation. The fuse holders are designed for snapping onto a 35mm DIN rail or mounted directly to the back plane of a panel. The fuse holder also uses a unique dovetail design that allows 30-ampere, 60-ampere and 100-ampere units to be ganged together. Eliminating the need for fuse reducers, the 30-ampere fuse may be inserted into the 60-ampere fuse holder and the 60-ampere fuse may be inserted into the 100-ampere fuse holder. The wire terminals are rated for dual wire termination. The CUBEFuse also offers permanent open fuse indication through a prominent front-panel viewport.

Spire, which primarily specializes in PC-cooling hardware, has introduced a hardware G-man of sorts to protect your major-bucks investment: the Spire PowerFuse SP162. This in-line cable/module assembly plugs into the six-pin power cable that runs between your precious PCI Express video board and your PC’s power supply. The idea is that it will shield the card from voltage surges and irregular power flow.
Of course, the PowerFuse is no substitute for a proper surge protector or uninterruptible power supply protecting your whole computing setup—without one, in a real power apocalypse, you could well be left with nothing but your graphics card! But the thinking here is to protect the card on the last mile, so to speak, from power irregularities that originate in the power supply itself.
