Eaton FAZ-B2/3-NA Circuit Breaker, 2A, 3-Pole, 277V

Meet the Eaton FAZ-B2/3-NA Circuit Breaker — a purpose-built solution for demanding industrial environments that need dependable 3‑pole protection on 277V circuits. With a 2 A nominal rating, this unit is designed to guard three-phase equipment, reduce downtime, and simplify maintenance in service, repair, and replacement projects.

• Three-pole protection for 3‑phase systems — interrupts all three conductors simultaneously to protect motors, conveyors, pumps, and control circuits from phase faults and overloads.
• 277V operation — tailored for common industrial distribution rails where 277-volt circuits power lighting, drivers, and multi‑phase equipment, delivering reliable performance in industrial plants.
• 2 A nominal rating — precise current protection that helps prevent nuisance trips on sensitive loads while still delivering rapid fault interruption when needed.
• Exact part compatibility — verify fit by the part number FAZ-B2/3-NA for reliable replacement in Eaton panels and to match your application requirements.
• Industrial-grade reliability — built to withstand the rigors of daily use in manufacturing, processing, and facility management, with durable construction and consistent trip characteristics.

This breaker is specifically suited for industrial service, maintenance, and replacement projects where coordinated protection of 3‑phase loads is critical. By pairing the FAZ-B2/3-NA with compatible Eaton panel systems, you can maintain system safety, protect valuable equipment, and streamline maintenance workflows.

Why choose this unit over low‑pole or single‑phase alternatives? It provides synchronized disconnection across all phases, which is essential for multi‑phase motors and equipment that require balanced protection. The 277V rating aligns with many industrial installations, reducing the need for voltage conversion or adapters during upgrades or new installs.

Practical guidance — to ensure proper function and safety, confirm the fit using the exact part number FAZ-B2/3-NA and review your panel’s compatibility and application requirements. If you’re unsure about compatibility or need help matching the part number to your equipment, send us a message and we’ll assist with a precise fit check.
