Eaton FAZ-D32 Three-Phase Arc Fault Circuit Breaker

The Eaton FAZ-D32 is a three-phase arc fault circuit breaker designed to protect 3‑phase 277 VAC circuits with a 32 A rating. Identified as FAZ-D32 NSMP, this AFCI device belongs to Eaton’s FAZ family and is intended for installation in commercial or industrial panel boards that require arc-fault protection on 277 VAC systems. It detects and interrupts arcing faults on three-phase feeders and branch circuits, helping reduce the risk of electrical fires by isolating the faulted portion of the system quickly. With a 32 A rating, it is suitable for medium‑duty power distribution tasks in facilities that rely on multi‑phase equipment and lighting powered from 277 VAC supplies. Typical applications include commercial buildings, warehouses, and light manufacturing environments where reliable arc-fault protection for 3‑phase circuits is needed.
