Square D FAL34090G 90A 3-Pole 480 V Circuit Breaker

Meet the Square D FAL34090G 90A 3-Pole 480 V Circuit Breaker—the reliable protector your 3‑phase, 480 V power distribution deserves. Built for industrial environments, this breaker delivers precise current protection across three poles, helping prevent equipment damage, unplanned downtime, and costly outages in demanding applications.

Key specifications

• Part Number: FAL34090G
• Brand: Square D (Schneider Electric)
• Current rating: 90 A
• Poles: 3
• Voltage rating: 480 V

Where this fits

Ideal for three‑phase, 480 V electrical systems in industrial settings—think manufacturing lines, heavy machinery, and control panels or MCCs (motor control centers) that rely on robust, code‑compliant protection. If your panel accepts FAL‑series breakers, the FAL34090G integrates smoothly with existing Square D infrastructure, ensuring consistent performance across your distribution network.

Why choose the FAL34090G

• Dedicated three‑phase protection: The 3‑pole design safeguards all conductors in a 480 V circuit, helping prevent imbalances that can damage motors and equipment.
• Part of a trusted family: As a Square D product, it’s designed to align with Square D panels and the broader FAL family for reliable compatibility and streamlined maintenance.
• Efficient replacement option: For legacy or upgrading projects, the 90 A rating provides a direct fit where a 90 A, 3‑pole breaker is required, reducing guesswork and downtime.
• Operational clarity: Clear labeling and straightforward wiring facilitate faster installation and safer operation by qualified professionals.

Practical considerations

Before installation, verify that your panel supports the FAL series and that the 90 A, 3‑pole, 480 V rating matches the protection needs of the circuit. For best results, consult the project’s electrical plans and the manufacturer’s installation guidelines to ensure proper mounting, wiring, and any required accessories. This part is most effective when paired with compatible Square D components to preserve system integrity and simplify future maintenance.

Practical use cases

• Protecting 3‑phase motors and drives in 480 V plant equipment
• Upgrading aging distribution panels to a standardized FAL-series protection scheme
• Replacement for legacy breakers in industrial control panels where a 90 A, 3‑pole, 480 V device is specified
