Eaton FAZ-D3/3-NA 3A 3-Pole 480 V Circuit Breaker

The Eaton FAZ-D3/3-NA is a 3-pole circuit breaker designed for three-phase electrical systems operating at up to 480 V. With a 3 A rating, this unit provides precise overcurrent protection for small-load circuits within commercial or industrial panels. The -NA suffix indicates North American compatibility, ensuring a proper fit in Eaton panel boards and switchgear that accept the FAZ family.

Key benefits and use cases:

• Three-pole protection safeguards all three live conductors in a 3-phase circuit, helping prevent unbalanced loads and equipment damage.
• 3 A protection is ideal for low-current control circuits, small motors, transformers, and other equipment that require tight current limits.
• 480 V voltage rating supports standard commercial/industrial distribution, enabling safe operation of drives, pumps, HVAC components, and other 3-phase loads in many facilities.
• Exact fit and compatibility with Eaton panels designed for the FAZ series simplifies replacement and maintenance, keeping installations consistent and compliant.
• Reliable interruption whenever an overload or fault is detected helps protect wiring and connected equipment from damage and reduces downtime.

Practical considerations and best-use guidance:

• Choose this part number, FAZ-D3/3-NA, when you need a precise 3 A, 3-pole, 480 V solution that matches existing Eaton gear.
• Ensure your load calculation aligns with a 3 A trip rating to promote proper coordination and safe operation across the distribution system.
• When replacing an older breaker, verify FAZ-series compatibility to avoid fitment issues and ensure secure terminal connections.

In summary, the Eaton FAZ-D3/3-NA 3A 3-Pole 480 V Circuit Breaker offers targeted, reliable protection for 3-phase circuits in commercial and industrial environments. If your application runs on 480 V and requires precise protection for modest-load, three-phase circuits, this breaker provides the right combination of compatibility, precision, and ease of use.
