Cutler Hammer GHB3080 80 Amp 3 Pole 480V Bolt-On Circuit Breaker

The Cutler Hammer GHB3080 is a robust 3-pole molded case circuit breaker designed for industrial and commercial electrical distribution systems. Manufactured by Eaton under the Cutler Hammer brand, this bolt-on breaker provides reliable overcurrent protection for circuits up to 480V AC. It features a thermal-magnetic trip mechanism that ensures quick response to overloads and short circuits, enhancing system safety and minimizing downtime. Key applications include panelboards, switchboards, and motor control centers in manufacturing facilities, data centers, and commercial buildings. Advantages over similar products include its compact G-frame design for space-efficient installations, high interrupting capacity for demanding environments, and compatibility with Eaton's BR and CH loadcenters. However, it may require specific panel compatibility checks, and its 14kA interrupting rating at 480Y/277V limits use in ultra-high fault current scenarios compared to higher-rated models like the GHC series. This unit appears load-tested and factory-sealed, indicating it has been verified for performance, making it a cost-effective option for replacements or upgrades. Benefits include easy installation with bolt-on connections and durable construction for long-term reliability, though users should note potential drawbacks like limited DC ratings for specialized applications.
