Eaton FAZ-D8/3-NA 8A 3-Pole 480 V Circuit Breaker

Eaton FAZ-D8/3-NA is a 3-pole circuit breaker engineered to protect 3-phase electrical systems up to 480 V. With a nominal current rating of 8 A, this part is designed for reliable interruption of overloads and faults on smaller 3-phase circuits in commercial and industrial environments.

• Part Number: FAZ-D8/3-NA
• Current Rating: 8 A
• Poles: 3
• Voltage Rating: 480 V
• Series/Family: FAZ (compatible with Eaton FAZ-series panels and distribution equipment)

Why this matters: in 3-phase installations, protecting motors, pumps, compressors, and other equipment from overloads and short circuits is crucial for uptime and safety. The FAZ-D8/3-NA delivers predictable trip behavior within Eaton’s FAZ ecosystem, helping you maintain consistent protection across your panel boards and service entrances.

Ideal use cases

• Protect 3-phase loads in 480 V distribution networks found in manufacturing floors, plant rooms, and large commercial facilities
• Standardize panel protection by using a recognized Eaton FAZ-series component across multiple enclosures
• Retrofit or replace aging breakers in 3-pole Eaton-compatible panels to restore precise protection characteristics

What sets it apart

Unlike generic breakers, the FAZ-D8/3-NA is designed for seamless integration within Eaton’s FAZ lineup, ensuring consistent trip curves, mounting compatibility, and wiring practices across your installation. This alignment reduces installation guesswork and simplifies maintenance when you’re stocking spare parts for a multi-panel environment.

Practical guidance
