Why this FAF12080 matters

When you’re upgrading or restoring an electrical panel, using the exact part—Square D FAF12080—ensures predictable performance and a proper physical fit. This single-pole, 80-amp breaker is tailored for circuits that require robust protection at 120V, making it a practical choice for residential or light commercial applications where Square D compatibility is essential.

Ideal use cases

• Replacing a failed or worn-out breaker in a Square D panel.
• Retrofit projects where an 80A, single-pole, 120V protection device is needed.
• Maintenance tasks that require a precise 80A, 1-Pole, 120V replacement to match existing panel specifications.

How to verify compatibility

To ensure a correct match, align the breaker’s specifications with your panel requirements:

• Confirm amperage = 80A, poles = 1-Pole, and voltage = 120V.
• Cross-check that the part number FAF12080 corresponds to your panel model and series as referenced in the panel’s labeling or OEM documentation.
• When in doubt, compare the physical form factor and mounting style to your current breaker to ensure a proper seat in the bus and enclosure.

Practical installation tips

• Power down the main service and verify there is no voltage present before handling the breaker.
• Handle the breaker with insulated tools and avoid touching the conductive terminals directly.
• Insert firmly into the panel slot and secure per the panel’s mounting guidelines; if torque specs are provided by the manufacturer, follow them precisely.
• Label the updated circuit clearly on the panel directory to reflect the new 80A, 1-Pole, 120V protection.
