Eaton EGB2100FFB - 100 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Eaton EGB2100FFB is a 100A, 480V, 2-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed to integrate seamlessly with Eaton and OEM systems, it delivers reliable performance where it matters most.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping to maintain stable electrical contact and minimize nuisance trips in environments with equipment movement or vibration.
• Thermal-magnetic trip unit delivers precise, repeatable protection by automatically responding to both overload and short-circuit conditions, reducing wear on downstream components and improving overall system reliability.
• OEM-compatible design is tailored to work with matching loadcenters and panelboards, enabling straightforward installation, easier replacement, and fewer compatibility considerations during upgrades or maintenance.
• 2-pole, 100A, 480V rating is ideal for controlling two hot legs in higher-voltage distribution circuits, making it suitable for a range of commercial and light industrial applications as well as certain residential setups.
• Versatility across settings supports residential, commercial, and light industrial electrical protection needs, providing a dependable solution for panelboards, service panels, and other distribution equipment.

Why this matters — In any electrical distribution system, reliable protection hinges on a sturdy connection, accurate trip behavior, and seamless compatibility with existing panels. The EGB2100FFB delivers on all fronts, helping you prevent damage to feeders and downstream devices while reducing downtime from unexpected trips.
