Eaton FD1100L - 277 V, 1-Pole Circuit Breaker | AmpState

The Eaton FD1100L 277V, 1-pole molded case circuit breaker is a dependable choice for protecting your branch circuits in panelboards and loadcenters. Designed for commercial and light industrial environments, it delivers precise, reliable protection when it’s most needed, while maximizing panel space with a compact form factor.

Why the FD1100L Stands Out

• Space‑efficient molded case design → enables efficient utilization of valuable panel space without sacrificing protection.
• Thermal-magnetic trip unit → provides stable, repeatable protection for both overloads and short circuits, reducing nuisance trips and ensuring predictable performance.
• OEM compatibility → engineered to pair with matching Eaton OEM loadcenters and panelboards for a seamless, reliable fit and consistent trip characteristics.
• Versatile applications → suitable for residential, commercial, and light industrial branch circuits operating at 277V.
