Eaton FDC3225 - 225 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton FDC3225 is a purpose-built 225 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Built for environments where reliability matters, this unit features a secure bolt-on mounting that creates a rigid, vibration‑resistant bus connection, reducing the risk of loose connections and trip anomalies in busy electrical rooms.

Engineered with a thermal-magnetic trip unit, the FDC3225 delivers stable, repeatable protection across a range of currents and ambient conditions. The thermal element handles overloads with smooth, predictable response, while the magnetic element provides instantaneous protection during short circuits, helping minimize damage to downstream devices and wiring. This combination supports safer, more predictable switching behavior in both routine operation and fault events.

Designed for seamless integration, the FDC3225 is compatible with matching OEM loadcenters and panelboards, enabling straightforward upgrades or replacements without extensive panel rework. Its three-pole design is ideal for three-phase systems common in commercial and light industrial applications, while its 225 A rating is well-suited for feeder protection and larger branch circuits in mixed-use facilities.

• Bolt-on mounting for a secure, vibration‑resistant bus connection and long-term reliability.
• Thermal‑magnetic trip unit provides dependable overload and short‑circuit protection with consistent trip characteristics.
• 3-pole design optimized for 3‑phase distribution networks commonly found in commercial and light industrial settings.
• 600 V rating supports higher voltage distribution within panelboards and loadcenters.
• 225 A current rating suited for feeder protection and larger branch circuits.
• OEM compatibility ensures plug-and-play replacement in compatible panelboards and loadcenters—minimizing installation time and downtime.
• Versatile applications ideal for residential, commercial, and light industrial environments where reliable, scalable protection is essential.

Ideal use cases

• Upgrading or replacing aging breakers in panelboards and loadcenters that require a sturdy bolt-on solution.
• Feeder protection for 3‑phase distribution in small to mid-size commercial spaces and light industrial facilities.
• New installations where a robust, vibration-resistant connection helps maintain consistent protection in equipment rooms and mechanical spaces.
• Retrofits in OEM panels that specify a compatible 3‑pole molded case breaker with a bolt-on mounting style.

Practical considerations

• Ensure the panelboard or loadcenter is rated for 3‑pole, 225 A devices and supports bolt-on mounting.
• Follow manufacturer torque specifications and alignment during installation to preserve connection integrity.
• Use as part of a coordinated protection strategy for both overcurrent and short-circuit scenarios in mixed-load environments.
