Bussmann

Bussmann is a leading manufacturer of fuses and fusible protection systems, offering comprehensive circuit protection solutions that comply with major standards such as UL, CSA, IEC, as well as European, DIN, and British Standards. Bussmann fuses are widely used across various applications, including industrial motor protection, power conversion, medium voltage, power distribution, telecommunications, electronics, and automotive sectors.

Bussmann series fuses are essential in industrial and commercial facilities, ensuring maximum protection for power systems. Their unique design prevents the use of incorrect fuse replacements, maintaining proper voltage and interrupting ratings. Additionally, Bussmann low-peak fuses provide enhanced current limitation, improving short-circuit current ratings.

A notable innovation from Bussmann is the CUBEfuse, the smallest power fuse on the market. Its rectangular design minimizes space requirements in control panels while offering high finger-safe ratings and improved workplace safety. The CUBEfuse’s selective coordination ratio of 2:1 within the low-peak family ensures that electrical outages are contained to the failed circuit.

In 2012, Eaton acquired Bussmann. The Bussmann division is a global leader in electrical circuit protection. Cooper, the parent company, is a diversified manufacturer of electrical components with $5.4 billion in revenue in 2011. Founded in 1833, Cooper’s success is driven by innovation, ethical business practices, and a focus on customer needs. Cooper operates in seven divisions, producing world-class products, including Bussmann fuses, explosion-proof equipment, lighting fixtures, and power systems. Positioned for growth in global infrastructure, energy efficiency, and electrical safety, Cooper’s industrial and utility markets made up 62% of sales in 2011, with 40% of sales outside the U.S. Cooper had manufacturing facilities in 23 countries as of 2011.
