Introducing the Eaton FAZ-D4/3 4A 3-Pole 480 V Circuit Breaker — a precise, three‑pole protection device designed for reliable 3‑phase circuit protection in industrial and commercial electrical panels. With a clear 4 A current rating and a 480 V voltage rating, this breaker is purpose-built to guard small 3‑phase loads while preserving smooth system operation.

Key specifications at a glance

• Current rating: 4 A
• Poles: 3 (three‑pole)
• Voltage rating: 480 V
• Part Number: FAZ-D4/3

Why this matters

The FAZ-D4/3 is more than a switch — it’s a targeted safeguard for your 3‑phase circuits. The 4 A rating provides dependable overcurrent protection for small motors, control circuits, and other lightweight 3‑phase loads, helping to prevent wiring damage, equipment failure, and downtime due to electrical faults. The 480 V rating ensures compatibility with typical industrial power systems, so you can rely on consistent performance in everyday operations.

Ideal use cases

• Protection for 3‑phase distribution panels and control gear in commercial or light industrial settings
• Safeguarding small motors and automation circuits powered by 3‑phase 480 V systems
• Replacement part for existing Eaton FAZ series installations, ensuring exact fit and compatibility

What sets it apart

Because this is a dedicated Eaton part (FAZ-D4/3), it offers precise compatibility with existing FAZ‑series panels and gear, reducing installation guesswork and downtime. The three‑pole design provides balanced protection across all phases, helping to maintain consistent duty on 3‑phase loads and simplifying panel labeling and maintenance planning for technicians and engineers.

Installation and practical tips

• Verify that your system operates at or near 480 V and that a 3‑pole, 4 A protection scheme aligns with your load requirements
• Power down the equipment and follow all local electrical codes when replacing or installing the FAZ-D4/3
• Ensure the replacement part matches the existing FAZ family specifications to maintain panel integrity and travel time during maintenance

For engineers and technicians managing 3‑phase power networks, the Eaton FAZ-D4/3 4A 3‑Pole 480 V Circuit Breaker provides a reliable, spec‑accurate solution that aligns with routine protection needs while simplifying sourcing and maintenance. This is the exact replacement part you can trust to keep your 3‑phase system safeguarded and operating smoothly.
