Eaton FDC3045L - 45 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton FDC3045L — a 45A, 600V, 3-pole molded case circuit breaker engineered to deliver dependable branch circuit protection in panelboards and loadcenters. Designed for compact installations and demanding environments, this breaker helps keep electrical systems safe, reliable, and easy to service.

• Compact molded case design minimizes panel depth and frees up valuable bus space, helping you maximize enclosure capacity without compromising protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection for both overloads and short circuits, reducing nuisance trips and maintaining consistent performance across temperature changes.
• 3-pole configuration supports three-phase circuits and ensures simultaneous disconnection of all conductors for safer, more predictable operation.
• 45A, 600V rating makes it suitable for a broad range of commercial and light industrial applications, from motor loads to lighting and control circuits.
• OEM panel compatibility designed to integrate smoothly with matching OEM loadcenters and panelboards, simplifying installation and future replacements.
• Versatile application ideal for residential, commercial, and light industrial installations, including upgrades to existing panels and new builds alike.

Why engineers and electricians choose the FDC3045L When space is at a premium or you’re upgrading a panel, this breaker delivers precise protection without forcing you to redesign the enclosure. The thermal-magnetic trip curve provides predictable protection across a range of operating conditions, so you can rely on consistent performance for motors, feeders, and branch circuits in everyday service environments.
