Eaton | FD1040LBP10 | Circuit Breaker | 40A | 1-Pole | 347V

The Eaton FD1040LBP10 is a 40A, 1-pole circuit breaker built for 347V circuits, delivering precise protection for commercial and industrial electrical systems. Designed for maintenance, retrofit, and replacement projects, this Eaton component keeps your panel running reliably while meeting essential safety standards.

Why choose this model? It pairs a single-pole form factor with a robust 40-amp rating for protecting a dedicated branch circuit in 347-volt networks. The result is targeted overcurrent protection that minimizes nuisance trips while guarding wiring and devices against faults.

• Exact specifications for compatibility: Amperage 40A, Poles 1-Pole, Voltage 347V. The FD1040LBP10 is the best reference part number to ensure a seamless fit.
• Designed for retrofit and replacement: Replace a failing breaker or upgrade an older panel without major rewiring or panel modifications.
• Parts you can trust: Engineered by Eaton, a long-standing name in electrical protection with consistent trip characteristics and mounting geometry across FD-series compatible panels.
• Targeted use cases: Ideal for protecting high-voltage branch circuits in lighting, HVAC, or machinery loads that run on 347V within commercial facilities.
• Installation considerations: Before ordering, confirm your panel accepts 347V 1-Pole devices and that the 40A rating matches the circuit being protected.

Practical tips to maximize performance:

• Label and document each circuit clearly so future maintenance calls out the correct device when service is needed.
• Keep a compatible spare on hand for quick swaps during routine maintenance or fault events.
• In systems with mixed voltages, ensure proper phase and voltage alignment to prevent nuisance trips or mis-matched protection.

With the FD1040LBP10, you’re choosing a dependable, purpose-built solution for protecting critical 347V circuits. Its straightforward form factor and precise rating help you maintain safer, more reliable electrical distribution in your facility.
