Eaton | FD4050 | Circuit Breaker | 50A | 4-Pole | 600V

Engineered by Eaton for demanding electrical installations, the FD4050 is a 50A, 4-pole circuit breaker designed to protect 600V circuits with precise, predictable shutoff across all conductors.

Key specifications

• Amperage: 50 A
• Poles: 4-Pole
• Voltage rating: 600 V
• Part number reference: FD4050
• Application: Circuit protection, maintenance, retrofit, and replacement in compatible Eaton panels

Why this 4-pole breaker matters

For panels that power three-phase equipment with a shared neutral or for circuits that require four-conductor protection, a 4-pole design ensures all conductors disconnect together. The FD4050 provides dependable protection across the entire circuit while meeting the needs of high-demand industrial environments.

Best use cases

• Maintenance and service of 3‑phase electrical panels that require 50A, 4‑pole protection.
• Retrofits in upgrades where existing breakers share the same FD form factor and voltage rating.
• New installations that specify 600V systems and four-pole protection for safe shutdown of all conductors.

Installation and compatibility tips

Always confirm fit and ratings before ordering. Use the part number FD4050 as the primary reference to ensure compatibility with your Eaton panel, bus configuration, and mounting style. Keep a spare on hand to minimize downtime during panel work.
