Eaton FAZ-D3/3-NA - 3A, 3-Pole, Circuit Breaker

The Eaton FAZ-D3/3-NA is a dedicated overcurrent protection solution engineered for demanding electrical environments. With a 3 A current rating and a 3-pole configuration, this circuit breaker delivers coordinated protection across all phases in 3‑phase systems, making it an ideal choice for panelboards, switchboards, and control panels where dependable safety and performance are essential.

Key specifications

• Current rating: 3 A
• Poles: 3‑Pole
• Breaker type: Circuit Breaker

Why the 3-pole design matters

Three-phase systems require simultaneous interruption across all conductors to prevent circulating fault conditions and unbalanced loads. The FAZ-D3/3-NA’s 3‑pole format ensures a single, coordinated trip for every phase, reducing the risk of partial protection and helping maintain safe, reliable operation in complex electrical distributions.

Ideal applications

• Industrial and commercial environments with 3‑phase distribution
• Electrical panels where compact, single-device protection is preferred for panelboards, switchboards, and control panels
• Motor control centers and OEM equipment requiring dependable overcurrent protection

What makes it stand out

• Specifically designed to provide dependable 3‑phase protection in a single, integrated device
• Suitable for use in distribution panels and motor control centers where safe operation matters most
• Simple integration into existing 3‑phase electrical architectures without sacrificing protection quality

Practical use and implementation tips

• Match the breaker’s 3 A rating to the protected circuit’s load to ensure appropriate tripping behavior during overloads
• Use in panelboards, switchboards, or control panels that require three-phase protection with common trip across all phases
• Plan for future expansion in 3‑phase systems by leveraging the 3‑pole design to maintain balanced protection as loads grow

For projects that demand precise, reliable three‑phase protection in industrial, commercial, or OEM applications, the Eaton FAZ-D3/3-NA 3A 3‑Pole circuit breaker offers clear advantages: straightforward integration, coordinated phase protection, and rugged performance that keeps distribution panels and motor control centers operating safely.
