Eaton FAZ-B3-3 - 3 A, 480 V, 3-Pole Circuit Breaker | AmpState

Introducing the Eaton FAZ-B3-3: a compact, 3-pole molded case circuit breaker designed for reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. With a 3 A rating and a 480 V service capability, this unit is purpose-built for 3-phase systems that demand precise protection without sacrificing space.

Why choose FAZ-B3-3 for your electrical distribution? Its thermal-magnetic trip unit delivers stable, repeatable protection, quickly disconnecting on short circuits while smoothly handling overloads. The molded case design keeps dimensions small to maximize usable panel area, helping you fit more circuits into the same footprint.

• Three-pole configuration – ideal for 3-phase circuits in commercial and light industrial settings.
• Thermal-magnetic protection – reliable response to overloads and instantaneous short-circuit trips.
• 480 V rated – suitable for higher-voltage branch circuits in compatible panels.
• Panelboard compatibility – designed to work with matching OEM loadcenters and panelboards for seamless replacements and retrofits.
• Compact design – efficient use of panel space, reducing enclosure width and simplifying layout.

Ideal use cases include stocking spare breakers for service upgrades, installing new 3-phase feeders in light commercial applications, or replacing faulty devices in existing Eaton-based panel systems. The FAZ-B3-3 supports reliable overcurrent protection across residential, commercial, and light industrial environments where 480 V, 3-pole protection is appropriate.
