Eaton FAZ-D20/3 - 20 A, 480 V, 3-Pole Circuit Breaker | AmpState

The Eaton FAZ-D20/3 is a 20A, 480V, 3-pole molded case circuit breaker engineered for dependable branch circuit protection in panelboards and load centers. Designed for commercial and industrial environments, this unit delivers precise protection where three-phase power is a given, helping you prevent costly faults before they affect operations.

Designed for space-efficient panel layouts, the compact molded case design maximizes available footprint in dense electrical enclosures. The thermal-magnetic trip unit provides stable, repeatable protection: the thermal element handles gradual overcurrent, while the magnetic element delivers a fast, decisive response to short circuits. This combination minimizes nuisance trips and ensures reliable interruption when it matters most.

• Compact molded case design: efficient use of panel space in load centers and panelboards
• Thermal-magnetic trip unit: stable performance across varying temperatures with fast magnetic response for short circuits
• OEM compatibility: proven fit with matching Eaton OEM load centers and panelboards for straightforward replacement
• Three-pole protection: reliable coordination across all three phases in 480V systems
• Versatile applications: suitable for residential-grade panel installations in a broader sense, as well as commercial and light industrial environments
