Eaton | FDB4040LBP10 | Circuit Breaker | 40A | 4-Pole | 600V

Meet the Eaton FDB4040LBP10 circuit breaker—a purpose-built solution for robust protection in industrial and commercial power layouts. This 40A, 4-Pole unit is engineered to safeguard 600V circuits with a coordinated trip across all poles, helping prevent damage from overloads and faults while keeping downtime to a minimum.

Specifically designed for maintenance, retrofit, and replacement projects where exact specifications matter, this breaker slots into Eaton-compatible panels with confidence. The part number FDB4040LBP10 is your most reliable reference for compatibility, reducing guesswork during upgrades or spares replacement.

Key advantages

• 40A protection for mid-range branch circuits, offering precise overcurrent control aligned with your system’s needs.
• 4-Pole design supports 3-phase applications and provides a synchronized trip across all poles for enhanced safety.
• 600V maximum system voltage suitable for industrial distribution networks and demanding installations.
• Exact compatibility identified by the line’s part number, FDB4040LBP10, simplifying procurement and installation.

Ideal use cases

• Retrofit projects in commercial or industrial panels that require a precise 4-pole, 40A breaker compatible with Eaton systems.
• Maintenance replacements where existing equipment operates at up to 600V and requires coordinated tripping across multiple poles.
• New installations in 3-phase power networks up to 600V that demand reliable, code-aligned protection.

Practical installation and ordering tips

• Always confirm fit and ratings before ordering—the FDB4040LBP10 part number is the strongest compatibility reference.
• Check panel labeling to ensure your enclosure accepts a 4-pole, 40A breaker of this design.
• Keep a spare on hand for critical infrastructure to minimize downtime in the event of a fault or routine maintenance.
