Eaton FAZ-B8-3N - 8 A, 480 V, 3-Pole Circuit Breaker | AmpState

The Eaton FAZ-B8-3N is a compact, 3-pole molded case circuit breaker engineered to protect 3-phase branch circuits in panelboards and load centers. With an 8A rating at 480V, it delivers dependable overcurrent and short-circuit protection where space and reliability matter most.

Key advantages that set this breaker apart:

• Space-efficient design — The molded case construction is optimized for tight panel configurations, freeing valuable bus space while delivering robust protection.
• Thermal-magnetic trip unit — A dual-action system combines a thermal element that senses gradual overcurrents with a magnetic mechanism that trips instantly on high-magnitude faults, providing stable, repeatable protection and reducing nuisance trips.
• 3-pole, 480V operation — Specifically suited for three-phase systems common in commercial and light industrial environments, enabling reliable protection for motors, conveyors, and other 3-phase loads at higher voltages.
• Cross-compatibility with OEM panelboards — Designed to integrate smoothly with matching OEM loadcenters and panelboards, ensuring reliable fit, coordination, and straightforward replacement when upgrading or maintaining systems.
• Versatile application range — Ideal for residential built spaces transitioning to light commercial, as well as small industrial outfits that require dependable protection for branch circuits feeding equipment and lighting.
