Eaton FD4045 is a molded case circuit breaker from the Series C family, designed for overcurrent protection in industrial power distribution systems. This 45A, 600V, 3-phase device provides LI (Long-Time and Instantaneous) protection through a thermal magnetic trip mechanism, with a 25kA interrupting capacity at 480V. The 4-pole, bolt-on unit is housed in an F Frame weighing 5 lb, featuring a compact construction suitable for panelboard and switchboard installations. It complies with UL and CSA standards for industrial circuit protection. Typical applications include motor control centers, lighting panels, and distribution boards requiring reliable branch circuit protection.
