Eaton | FDB4050LBP10 | Circuit Breaker | 50A | 4-Pole | 600V

The Eaton FDB4050LBP10 is a rugged, high-ampacity circuit breaker designed for demanding electrical environments. Built to support maintenance, retrofit, and replacement projects, this 4-pole unit delivers reliable protection for 600V circuits while simplifying panel upgrades and service work.

Key specifications at a glance

• Amperage: 50A
• Poles: 4-Pole
• Voltage rating: 600V
• Part number: FDB4050LBP10

Why a 4-pole design matters in three-phase systems, a 4-pole circuit breaker provides simultaneous disconnection of all conductors, including the neutral when applicable. This enhances safety during maintenance and ensures clean, complete interruption of power to controlled loads, which is especially important for motor drives, processors, and other sensitive equipment in industrial settings.

Ideal use cases

• Maintenance and retrofits in existing 600V electrical panels where matching specs are required
• Replacement in service panels for consistent performance and lifecycle uptime
• New installations for 600V, 50A circuits that demand robust, multi-pole protection
• Applications involving three-phase motor power, controls, or heavy machinery wiring where neutral or multiple conductors must be simultaneously isolated

Practical considerations for your purchase

• Compatibility first: The part number is the best reference for ensuring a correct fit and ratings. Confirm fit and ratings before ordering.
• Application fit: Use in panels designed for Eaton FDB-series devices to maintain warranty and performance expectations.
• Installation mindset: When replacing an existing breaker, align the new unit with the same voltage class and amperage to preserve circuit protection levels.

With the Eaton FDB4050LBP10, you gain a dependable, high-capacity circuit breaker purpose-built for 600V electrical systems. It’s a precise choice for professionals tackling panel upgrades, equipment retrofits, and essential replacements—delivering consistent protection and peace of mind across demanding industrial, commercial, and facility applications.
