Eaton FAZ-D3/3 - 3 A, 480 V, 3-Pole Circuit Breaker | AmpState

Experience dependable three‑phase protection with Eaton FAZ-D3/3 — a 3 A, 480 V, 3‑pole molded case circuit breaker built for demanding panelboards and load centers.

Compact protection you can rely on

• 3‑pole design for balanced three‑phase circuits, preventing uneven loading and arcing in commercial and light industrial installations.
• Thermal‑magnetic trip unit provides stable, repeatable protection: the thermal element handles normal overloads; the magnetic element delivers a rapid response on short‑circuits.
• Compact molded‑case construction minimizes panel footprint and allows easier field replacement in crowded panelboards.
• Designed to be compatible with matching OEM load centers and panelboards, simplifying upgrades and replacements without rewiring.
• Versatile for residential, commercial, and light industrial applications where compact, reliable protection is needed for 480 V three‑phase feeders.

What problems does it solve?

It prevents costly equipment damage and downtime by interrupting fault currents and protecting wiring and devices downstream. By using a single device that combines overload and short‑circuit protection, you reduce panel complexity and improve maintenance efficiency.

Practical use cases

• Three‑phase motor feeders in HVAC systems, conveyors, or machine controls powered from 480 V panels.
• Lighting feeders and power distribution blocks in commercial spaces that run on 480 V three‑phase service.
• Panelboard upgrades where OEM compatibility ensures straightforward replacement without adapting existing bus bars or mounting channels.
