The designation "CH" on Eaton circuit breakers and load centers historically stands for "Cutler-Hammer," commemorating the legacy engineering firm whose premium product line was acquired and integrated into Eaton's electrical distribution portfolio. Today, the CH designation represents Eaton's elite, professional-grade residential tier, symbolizing a slim profile, metal-to-metal latching architecture, a lifetime manufacturer warranty, and superior craftsmanship built for maximum reliability and performance.
