Eaton FD3100L - 100 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton FD3100L 100A, 600V, 3-pole molded case circuit breaker is engineered to guard your most vital electrical circuits with precision and reliability. Designed for panelboards and loadcenters, this breaker delivers dependable branch circuit overcurrent and short-circuit protection in residential, commercial, and light industrial installations.

• Compact molded case design - Maximizes panel space without compromising protection, making it ideal for crowded or retrofit panels where every inch counts.
• Thermal-magnetic trip unit - Provides stable, repeatable protection by responding to both sustained overcurrents and instantaneous short circuits, helping prevent nuisance trips and equipment damage.
• Three-pole, 100A, 600V configuration - Delivers synchronized disconnection across all three phases, enhancing safety and protective coordination in multi-phase systems.
• OEM-compatibility - Built to work seamlessly with matching Eaton OEM loadcenters and panelboards, ensuring straightforward installation and consistent performance.
• Versatile application - Suitable for a wide range of environments—from residential electrical panels to commercial lighting and small industrial circuits—where reliable protection is essential.

Why this matters in real-world setups: the FD3100L combines a space-efficient form with robust protection logic. In a retrofit or new panel installation, you’ll appreciate the streamlined fit alongside other protective devices, while the thermal-magnetic trip helps maintain uptime for critical circuits during temporary surges or fault conditions. The 3-pole design ensures that all phases clear together, reducing the risk of circulating fault currents and protecting equipment more effectively than single- or two-pole options in multi-phase networks.
