Eaton FDC3125 - 125 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton FDC3125—a dependable 125 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to protect your electrical system where it matters most. Sourced through AmpState, this unit is built to deliver consistent, reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters.

• Secure bolt-on mounting: a rigid, vibration-resistant bus connection that stays tight under heat and vibration, reducing the risk of loose connections and arcing.
• Thermal-magnetic trip unit: combines thermal overload protection with magnetic short-circuit protection for stable, repeatable performance across varying loads and temperatures.
• 125 A, 600 V rating: optimized for demanding feeder circuits and typical commercial and light industrial loads, while safely handling residential applications that require robust protection.
• 3-pole configuration: designed for balanced 3-phase systems, making it ideal for motors, compressors, and other 3-phase equipment common in commercial spaces.
• OEM-compatible bolt-on design: matches with corresponding load centers and panelboards, enabling straightforward installation, reliable alignment, and easy serviceability.
• Diversified applications: suitable for new installations, panel upgrades, and retrofit projects in homes, offices, retail, and light industrial environments.

Why choose this bolt-on breaker over other formats? The bolt-on approach provides a sturdier bus connection that resists loosening from vibration, temperature cycling, and panel movement—crucial in busy electrical rooms and spaces with frequent service. The Eaton FDC3125’s thermal-magnetic protection ensures fast, predictable trips for short circuits while avoiding nuisance trips during normal operation, giving you peace of mind and fewer service interruptions.
