About Bussmann Products

100 Years of Innovation

It’s been 100 years since the Bussmann brothers first started producing fuses from the basement of their home. And in that time span, Bussmann has grown from providing fuses for horseless carriages and World War II aircraft, to offering more than 30,000 products. From humble beginnings in St. Louis, Missouri, to a global product and distribution network, the Bussmann name is synonymous with technological innovation. In fact, over the past 100 years, Bussmann products have received more than 3,000 utility and design patents, with more than 350 global active patents.

Today, Bussmann products continue to reflect a long-standing tradition of providing fusible circuit protection and electrical safety solutions that help protect equipment and enable reliable, efficient power distribution. And now that Bussmann products are part of Eaton, the industry’s top innovators of fuse technology and circuit breakers have united to provide ultimate leadership in circuit protection.

Our legacy of developing innovative products and solutions stems from a team of highly talented industry experts. We couldn’t have secured our position as a leader in circuit protection without our employees, our customers, and our community. We hope you’ll join us in celebrating 100 years of innovation.

I am an engineer working in Mexico City for Schneider Electric Company, and I am working on projects where we will use Bussmann fuses and fuse blocks.  I never read your story, but I think it is amazing you have a great company.

By Gerson Juan de Dios Cruz


Here is a photo of fuse testing back in the day.  They used mercury thermometers, incandescent lamps (for load), fans to cool the lamps, analog (needle) current meters and wall clocks for timing. Wow, has the technology changed since then!

By William Holland


I worked at Bussmann for about 15 years.  I started at the plant on St. Louis Avenue and then moved out to Ellisville.  I had an awesome time working at Bussmann and met some wonderful friends.  I still keep in contact with some of them.  I loved working on the crimper machine.  I’ll always remember all the good memories from Bussmann.

Here’s a picture of Al Bussmann at a trade show in 1952.

My great-grandfather immigrated in the last 1800’s and built our family’s farm house. He installed electricity in 1945. The installed Cutler Hammer box was manufactured in 1940. From day one, we have always used Bussmann plug fuses. Here’s an image with the two overcurrent protection companies, who now play for the same team, working together in 1945 on a resi fusible solution that still works today.
