Square D | FAP34080 | Circuit Breaker | 80A | 3-Pole | 480V

Meet the Square D FAP34080 circuit breaker—a precise, mission-critical protector for 480V three‑phase systems. With an 80A rating and a three-pole design, this unit is built to interrupt all three phases simultaneously, safeguarding motors, drives, and distribution equipment in demanding industrial and commercial environments. Designed for maintenance, retrofit, and replacement projects, it ensures you can restore reliability quickly without sacrificing compatibility.

• Amperage: 80A — reliable overcurrent protection for medium-to-heavy load applications.
• Poles: 3-Pole — ensures symmetrical interruption across all phases in 480V systems.
• Voltage: 480V — suitable for standard industrial power distribution and equipment geared to high-voltage three‑phase networks.
• Compatibility reference: Part number FAP34080 is the best guide for alignment with Square D panels and compatible enclosures.

Important fitment note: Confirm fit and ratings before ordering. The part number is the most reliable reference to ensure seamless compatibility with your existing Square D panel, switchgear, or distribution board.

Who should consider this breaker? Electrical engineers, facility managers, and maintenance technicians working in manufacturing, data centers, or large commercial spaces where 480V three‑phase protection is essential. If you’re performing a retrofit or replacement, choosing the exact FAP34080 helps you avoid fitment issues, mismatched trip characteristics, or panel incompatibilities that can lead to downtime.

Use cases and practical scenarios:

• Replacing a failed 480V three‑phase breaker in a Square D panel without modifying the enclosure.
• Upgrading or retrofitting electrical rooms to maintain safe, code-compliant protection for motors and drives.
• Standardizing components across multiple panels to simplify maintenance and parts inventory.

Why this specific breaker stands out: its exact alignment with Square D standards means faster installations, predictable mounting geometry, and reliable electrical protection for 480V systems. When compared to generic substitutes, the FAP34080 delivers the confidence that your protective device will seat correctly, trip appropriately, and integrate with your existing protection schemes.
