Eaton FAZ-D4/3N - 4 A, 480 V, 3-Pole Circuit Breaker | AmpState

The Eaton FAZ-D4/3N is a 4A, 480V, three-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Engineered to integrate with matching OEM loadcenters, this unit brings precise, reliable protection to residential, commercial, and light industrial electrical systems.

Key advantages that matter in real-world panels

• Compact molded case design maximizes space efficiency in crowded panels, helping you fit more protection without compromising performance.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining overload sensing (thermal) with fast short-circuit response (magnetic) for reliable fault classification.
• OEM-compatible installation seamlessly integrates with matching Eaton load centers and panelboards, simplifying procurement, stocking, and serviceability.
• Versatile application ideal for multiple environments—from home electrical panels to light commercial and small industrial installations requiring robust 3-pole protection at 480V.

Why this matters for your electrical system

In a 480V, three-pole configuration, the FAZ-D4/3N guards downstream circuits from overloads and short circuits, reducing the risk of equipment damage and electrical fires. The 4A rating is particularly well-suited for control circuits, lighting feeds, and select small motor loads where precise, predictable protection is essential for safety and reliability.
