Eaton | FAZ-C40/3-NA | Circuit Breaker | 40A | 3-Pole

Engineered for dependable protection in Eaton panels

The Eaton FAZ-C40/3-NA is a genuine 40-amp, 3-pole circuit breaker designed for maintenance, retrofit, and replacement projects where exact specifications matter. This is not a guess—it's a direct match to Eaton’s FAZ family, built to integrate smoothly with compatible panels and deliver consistent performance when the time comes to refresh your electrical protection.

What makes it stand out

• Exact 40A protection—provides reliable overload protection while supporting typical load profiles in commercial and light-industrial environments.
• Three‑pole design—ideal for three-phase circuits and panel configurations that require simultaneous protection across all poles.
• OEM accuracy—the part number FAZ-C40/3-NA is the best reference for compatibility, reducing guesswork during maintenance or retrofit.
• Replacement-ready—a practical choice for service teams refreshing aging components or upgrading panels that rely on Eaton FAZ-series breakers.

Use cases and scenarios

Ideal for swapping a worn or failed 3-pole breaker in an Eaton-compatible panel, retrofitting older equipment to meet updated electrical standards, or stocking a spare for planned replacement in three-phase systems. Because this unit maintains the same electrical characteristics as existing FAZ components, it minimizes compatibility surprises during critical outages or upgrades.

Compatibility and installation tips

Important: Always confirm fit and ratings before ordering. Use the part number FAZ-C40/3-NA as the primary reference to verify compatibility with your panel. If your system already uses Eaton FAZ-series breakers, this unit will align with the same mounting footprint and protection scheme, simplifying installation and reducing downtime.

Care and handling

Store in a dry, clean environment and follow standard electrical safety practices during installation. If you’re unsure about the exact replacement requirement, consult your panel’s documentation or a qualified electrician before proceeding.
