Eaton EGS3125FFB - 125 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Experience dependable branch circuit protection with the Eaton EGS3125FFB — a 125A, 600V, 3-pole bolt-on molded case circuit breaker designed for panelboards and load centers. Built for real-world electrical environments, it delivers stable, repeatable protection in residential, commercial, and light industrial applications.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight through field operating conditions, reducing the risk of arcing or loose connections over time.
• Thermal-magnetic trip unit delivers reliable overcurrent and short-circuit protection, responding to both slow-increasing overloads and instantaneous faults with consistent trip performance.
• 3-pole design enables coordinated protection across all three phases, ideal for three-phase systems commonly found in commercial and light industrial setups.
• 125A, 600V rating supports substantial branch-circuit loads while tolerating standard commercial/industrial distribution environments, delivering robust protection for motors, feeders, and lighting circuits.
• OEM-compatible mounting is designed to work seamlessly with matching Eaton OEM load centers and panelboards, simplifying replacements, upgrades, and field servicing.
• Versatile application engineered for residential, commercial, and light industrial installations, making it a practical choice for new builds and panel upgrades alike.

Where this breaker shines

• Upgrading or expanding panelboards in small to medium commercial spaces where reliable three-phase protection is required.
• Replacing aging or incompatible breakers in Eaton-compatible load centers to restore protected capacity without extensive rewiring.
• Protecting distributed motor loads, lighting circuits, and control feeders in light industrial environments where dependable trip behavior matters.
