Eaton FAZ-Z8/3 - 8 A, 480 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton FAZ-Z8/3, a purpose-built 3-pole molded case circuit breaker rated at 8A and 480V. Designed for dependable branch circuit protection in panelboards and loadcenters, this unit guards your electrical system against overcurrent and short-circuit events with precise, reliable performance.

• Compact, space-efficient design: The molded case form maximizes panel footprint, making it easier to fit into tight panelboards and loadcenters without compromising protection.
• Thermal-magnetic trip unit: Combines thermal sensing for gradual overload protection with magnetic tripping for instantaneous response to short circuits, delivering stable, repeatable protection across varying loads and surges.
• Three-pole architecture: Specifically engineered for 3-phase power, ensuring balanced protection across all phases and minimizing the risk of phase imbalances in commercial or light industrial wiring.
• OEM-compatible performance: Designed to pair with matching Eaton OEM loadcenters and panelboards, enabling straightforward replacements and consistent, reliable operation within existing systems.
• Versatile applications: Ideal for residential, commercial, and light industrial electrical networks that rely on 480V distribution and controlled current protection.

This FAZ-Z8/3 module is a practical choice for upgrading or extending protection in 3-phase circuits. It’s especially well-suited for panelboard or loadcenter upgrades, protection of small 3-phase equipment, or as a smart, compatible replacement in Eaton-based electrical infrastructures. With an 8A rating at 480V, it provides targeted protection for circuits where precise current limitation and rapid fault isolation are essential.

Who benefits most: electrical distributors, contractors, and facility managers who need a reliable, compatible 3-pole breaker that integrates seamlessly with existing Eaton systems, while delivering predictable protection for small to medium 3-phase loads.

How it compares to alternatives: This molded case breaker emphasizes tight integration with Eaton OEM panelboards, ensuring alignment with factory-rated trip curves and termination geometry. Its thermal-magnetic design reduces nuisance trips and provides immediate response to faults, traits that are particularly important in commercial or light industrial environments where uptime matters.

Practical tips: - Verify that your distribution setup is compatible with 480V 3-phase systems before installation. - Use the unit as a dedicated protective device for a specific 3-phase circuit to maintain clear fault isolation. - When replacing an existing breaker, confirm the FAZ-Z8/3’s trip characteristics align with your panelboard’s specifications to ensure consistent protection behavior.
