Eaton FDB2080 - 80 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Eaton FDB2080 is a rugged, bolt-on molded case circuit breaker engineered for reliable branch circuit protection in panelboards and load centers. With an 80 A rating and a 600 V capacity, it’s built to handle everyday commercial and light industrial demand while staying dependable in demanding environments.

• Secure bolt-on mounting provides a rigid, vibration‑resistant bus connection. This design minimizes connection loosening over time, helping maintain consistent protection and reducing nuisance trips in installations subject to vibration or movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding appropriately to both overloads and short circuits. The thermal element handles sustained overcurrent, while the magnetic element delivers instantaneous trips for high‑fault conditions, safeguarding wiring and equipment.
• OEM-compatible and panel-ready designed to work with matching Eaton OEM load centers and panelboards, simplifying replacement and ensuring seamless integration with existing systems.
• Two‑pole, 80 A, 600 V molded case design strikes a balance between reliable protection and compact form factor, ideal for 2‑pole circuits that require coordinated protection and easy mounting in standard enclosures.
• Versatile across sectors suitable for residential, commercial, and light industrial applications—from home distribution panels to small business panels and modest industrial control setups.
