Cutler Hammer
Eaton
Founded in 1893 by Harry Henderson Cutler and Edward West Hammer, Cutler-Hammer revolutionized the power control industry with the first automatic motor starter in 1900—an innovation that laid the groundwork for modern motor control technology. The company later designed control systems for the Panama Canal and became known for its leadership in vacuum-tube current control and automation. In 1978, Cutler-Hammer became part of Eaton Corporation, combining its century-old legacy with Eaton’s global expertise in power management, switchgear, and electrical control systems. Today, Eaton Cutler-Hammer continues to provide advanced circuit protection, switching devices, and power distribution solutions for industrial, commercial, and renewable applications.
The Eaton Cutler-Hammer product range features durable and high-performance circuit breakers, fuse protection, and control components designed for precision, safety, and flexibility. The NZM4 Series molded case circuit breakers (MCCBs) offer adjustable trip settings and modular accessories for reliable power protection, while N4 Series breakers deliver intelligent control and high interrupt ratings for large-scale industrial systems. QC Series breakers ensure reliable branch protection for commercial and residential systems, and PV Series fuses safeguard solar installations. Each solution is engineered to meet global standards (UL, CSA, IEC), ensuring consistent performance and safety in demanding environments.
Built for industries that power the world, from infrastructure and energy to manufacturing and automation—Eaton Cutler-Hammer products combine innovation, reliability, and scalability. With benefits including high interrupting capacity, modularity, and long service life, these components are trusted by engineers worldwide.
