Do You Need To Be Encouraged To Fuse Your Designs?

At least twice a week I wake up wondering if this is in fact the twenty-first century, and not because of the upcoming presidential elections, although they are playing a part. One of two things happen: there’s a presentation of simple, common-knowledge technology made extremely complicated with a long-winded diatribe, and/or a presentation of highly complicated technology made simple, understandable, and palatable by excellent demonstrators. Although it should be clear which is most favorable, to avoid any confusion, it is the second or latter one if you will.

As an example of a very simple technology, let’s use the fuse. Almost everyone knows what a fuse is and what it does. Not everyone would understand the theory of current flow and how to calculate what value fuse is required in a design. However, most would know that a blown fuse means their device is not working and replacing said fuse might get the device up and running again. And if not, they might know it’s time to either get the unit repaired or replace it.

The fuse, to me, is a no brainer technology, a necessity to protect one and one’s electrical device. A simple device that costs little and can save much, end of story, right? No, you’re not getting off that easy.

Pro Fuse International is a global association that advocates use of fuses and fuse technology. The organization was founded in 1998, a few years shy of a century in which fuses became standard operating equipment, particularly in vacuum-tube-based products. According to the association, and I quote, “The fuse is recognized as a proven technology – yet its evolution is continuous, with ongoing investment in design and engineering in order to adapt the technology for important new applications and emerging market needs.”

The banter continues with, “The benefits of fuses and fuse-based devices are significant for anyone involved with the electrical industry – as well as for its consumers.  The primary benefits are the guaranteed safety of users and assured reliability of the installation - plus cost savings in terms of design, purchase and maintenance.  As well as protecting against over currents and their associated risks, fuses also offer considerable environmental benefits, including their ability to be recycled.”

Just a couple of points and questions to discuss:

Question: Any engineers, designers, hobbyists, and/or consumers out there that do not know this or disagree?

Point: The bit about recycling is not completely true in that not all fuses benefit the environment. Most people chuck those blown fuses into the common trash. Resettable fuses better address environmental issues.

Question: Is an organization necessary that reaffirms the importance of fuses? You decide. To learn about the latest advances in fuse technology, visit
