Eaton FDB2090 - 90 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton FDB2090 — a robust 2-pole, 90A, 600V bolt-on molded case circuit breaker engineered to protect branch circuits with precision in panelboards and loadcenters. Built to endure, it delivers dependable overcurrent and short-circuit protection wherever you need reliable electrical distribution.

Key advantages that keep circuits safe

• Secure bolt-on mounting creates a rigid, vibration-resistant bus connection, helping maintain a solid electrical path even in environments with movement or vibration.
• Thermal-magnetic trip unit provides stable, repeatable protection—the magnetic element responds quickly to short circuits, while the thermal element handles overloads, reducing nuisance trips and ensuring predictable performance.
• OEM-compatible design is ready to partner with matching Eaton load centers and panelboards, enabling straightforward replacement and seamless integration into existing systems.
• Versatile applications—suitable for residential, commercial, and light industrial use, making it a versatile choice for a wide range of panel configurations.
