Eaton GHB3045 3-Pole 45A Molded Case Circuit Breaker

The Eaton GHB3045 is a robust 3-pole molded case circuit breaker designed for reliable overcurrent protection in commercial and industrial electrical systems. Rated at 45 amps, it features bolt-on mounting for secure installation in panelboards and switchboards, with an interrupting capacity of 14 kA at 480Y/277V AC, making it suitable for applications requiring moderate short-circuit protection. Key features include thermal-magnetic trip technology for precise response to overloads and faults, compatibility with CU/AL conductors, and operation in temperatures up to 40°C. Advantages over similar products include Eaton's reputation for durability and ease of integration into legacy systems like Cutler-Hammer panels. Benefits encompass enhanced safety through quick fault interruption, reducing downtime and equipment damage. Drawbacks may include its non-adjustable trip settings, limiting customization compared to more advanced models, and potential obsolescence in modern high-interrupt applications. Ideal for lighting, motor, and distribution circuits in facilities like manufacturing plants or office buildings. This unit appears used but load-tested, ensuring functionality, with no visible damage to critical components. It offers cost-effective protection without the need for frequent maintenance, outperforming basic fuses in resettability and reliability.
