What Brands Does Eaton Own?

Eaton owns Cutler-Hammer, Bussmann, Crouse-Hinds, and Klockner-Moeller, and it produces the successor lines for Westinghouse electrical distribution equipment. Eaton acquired the Westinghouse Distribution and Control Business Unit in 1994, Klockner-Moeller in 2008, and Cooper Industries, which brought Bussmann and Crouse-Hinds, in 2012. For the full history behind those acquisitions, visit our About Eaton page.

Are Eaton and Cutler-Hammer the Same?

Cutler-Hammer is an Eaton brand, and current Cutler-Hammer-branded parts are made by Eaton on the same product lines. That is why a current Eaton part usually fits equipment labeled Cutler-Hammer. Older Westinghouse-era equipment often needs a specific legacy frame rather than a current production substitute, so confirm the catalog number before ordering.

Where to Buy Obsolete Eaton and Westinghouse Parts

What sets Essential Electric Supply apart is not just carrying current Eaton stock. Most electrical distributors do that. It is stocking compatible replacement parts for the discontinued Cutler-Hammer and Westinghouse equipment still installed in older buildings. That kind of support gets harder to find once a product line is retired.
