• Intended use: maintenance, retrofit, and replacement projects requiring exact specifications

Why this breaker stands out

• Exact spec alignment: This NEF431050 matches the amperage, pole count, and voltage of your existing three-phase 480V system, helping minimize downtime during replacement or retrofits.
• Part-number-driven compatibility: Rely on the NEF431050 as the best reference for cross-checking fit with your panel, MCC, or switchgear documentation.
• Industrial-duty construction: Built to endure the mechanical wear, temperature variations, and continuous operation common in plant environments.
• Maintenance- and upgrade-friendly: Ideal for upgrades or spares in maintenance inventories where precise matching is critical.

Practical use cases

• Replacing a failed breaker in a 3-phase, 480V distribution panel or motor control center.
• Retrofits where existing equipment requires a precise 50A, 3-pole, 480V protection device.
• Spare part in maintenance stock to speed up service calls and reduce downtime.

Quick compatibility checklist

• Verify the part number: NEF431050 is your primary reference for compatibility.
• Confirm electrical ratings: 50A, 3-Pole, 480V match your system and device labeling.
• Check panel and MCC documentation to ensure the physical fit and termination style align with your enclosure.

Note: Confirm fit and ratings before ordering to ensure seamless integration with your existing electrical infrastructure.
