Eaton FD3225L - 225 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton FD3225L — a 225 A, 600 V, 3-pole molded-case circuit breaker designed to provide dependable branch circuit overcurrent and short-circuit protection for panelboards and loadcenters. Built to fit seamlessly into existing Eaton systems, it balances compact size with robust protection, making it a smart choice for modern electrical distributions.

Why this breaker stands out

• Compact molded-case design saves panel space while preserving effortless access to wiring and terminations, helping you fit more circuits into smaller compartments without compromising protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance across temperature variations and fluctuating loads, reducing nuisance trips and promoting reliable coordination with other protective devices.
• 3-pole configuration supports three-phase systems common in commercial and light industrial environments, enabling balanced protection for multi-phase distributions.
• 600 V rating expands its applicability to higher-voltage panel systems and equipment protection scenarios typical in non-residential settings.
• 225 A continuous rating provides strong protection for feeders and branch circuits that handle substantial current loads, while maintaining safe interrupting capabilities.
• OEM compatibility designed to work with matching Eaton loadcenters and panelboards, ensuring a reliable fit and synchronized protection profiles across your installation.
• Versatile application suitable for residential, commercial, and light industrial use cases—from service panels to distribution centers and equipment panels.

Applications and practical use

The FD3225L excels in environments where space is at a premium but protection can’t be compromised. It’s an ideal replacement for aging breakers in existing Eaton panelboards, a strong candidate for new commercial or light industrial installations, and a practical choice for upgrading protection in mechanical rooms, data centers, and electrical closets. With its OEM-compatible design, technicians can mix and match with confidence, reducing installation time and inventory complexity while maintaining consistent protection performance.
