Partnering to Develop Custom Solutions


An industry-leading manufacturer and distributor of HVAC systems was designing a new panel for a new piece of equipment that did not pass testing due to thermal considerations. In order to increase airflow through the panel, engineers were forced to implement additional fans into the panel design.


Eaton’s Bussmann business proposed to use our 600V/60A Class R fuse block with our energy efficient Fusetron fuses. After testing, the Bussmann solution ran cooler in the same footprint and allowed the cooling fans to be removed from the panel design. This change reduced the overall operating temperature in the panel, eliminated the cost of the additional fans, and reduced the required assembly labor of the panel.


Bussmann offers a comprehensive portfolio of AC and DC circuit protection solutions. And with Eaton and Cooper united, our offering of products and services encompasses broader solutions for HVAC/R applications, including:

  • Overcurrent protection
  • Overvoltage protection
  • Disconnects
  • Fuse blocks, power distribution blocks, terminal blocks
  • Contactors, motor starters, relays
  • Motor control centers
  • Medium voltage motor control
