CUBEFuse

When it comes to designing control panels, space is at a premium. Eaton engineers realized that a step-change in fuse design wasn’t enough. They needed to dramatically shrink its footprint.

After months of prototyping and testing the Bussmann series CUBEFuse emerged and, incredibly, it was up to 70% smaller than any other Class J fuses on the market. By challenging the traditional fuse shape, CUBEFuse makes it possible to dramatically shrink panel size. But what’s most exciting is the total CUBEFuse package. Not only is it easy to install, it’s finger-safe to protect against accidental contact during installation or service, and it helps reduce arc flash hazards.

Because it’s so small in size, the design impact of the CUBEFuse is huge. Traditionally, engineers had to make design concessions based on the physical size of their fuses. By reducing the CUBEFuse footprint, now panel design could be reduced as well. This means more wall space for new enclosures and monitors — and more physical space for intelligent controls within machines.

Though the implications are obvious for any UL 508A panel shop, Eaton customers across industries see CUBEFuse as a critical way to improve system designs. Whether it’s in HVAC or alternative energy, CUBEFuse allows manufacturers to find significant space and cost savings. Eaton helped one leading wind energy OEM maximize space by custom engineering a higher-voltage CUBEFuse (690V-rated) to fit into the incredibly complex controllers of next-generation wind turbines. The innovative CUBEFuse design also helped solar installers and manufacturers meet new standards and design internal disconnect capabilities into solar inverters without having to increase the overall form factor. It’s a true collaboration point, where one innovation drives the next.

This kind of positive ripple effect is at the very heart of Eaton innovation. From data centers to motor controls, Eaton sales teams are finding new ways to leverage CUBEFuse in the company’s own product lines and customer solutions to save precious space, while never compromising product safety. Innovations like CUBEFuse show that when you question even the smallest assumption — “a fuse is a fuse,” for instance — the possibilities become truly exciting.
