Is Cutler-Hammer Still in Business?
No, not as an independent company. Cutler-Hammer products are made and sold by Eaton, which acquired the Westinghouse Distribution and Control Business Unit in 1994 and has used the Cutler-Hammer name on circuit breakers, motor controls, and switches ever since. Read the full Cutler-Hammer brand history for the acquisition story, or learn more about Eaton, the parent brand.
Are Cutler-Hammer and Eaton Breakers Interchangeable?
For current production lines, yes. Cutler-Hammer-branded and Eaton-branded breakers come off the same product lines, so a current Eaton BR or CH breaker fits a panel labeled Cutler-Hammer. Older Westinghouse-era frames are a different question and often require a specific legacy catalog number, so confirm the part before ordering. Panel labeling and UL listing determine what is approved for your installation.
Where to Buy Obsolete Cutler-Hammer Parts
Most industrial distributors carry standard Eaton Cutler-Hammer stock for new installations. Essential Electric Supply fills the gap on the older side, stocking discontinued Cutler-Hammer and Westinghouse parts that have been out of production for years, whether new, surplus, or hard to find elsewhere.
