Eaton FAZ-B20/3 20A 3-Pole 480 V Circuit Breaker

Eaton FAZ-B20/3 is a 20 A, 3-pole circuit breaker purpose-built for 480 V systems. This part, identified by FAZ-B20/3, delivers reliable overcurrent protection for three‑phase distributions, making it a dependable choice for industrial and commercial electrical panels that operate at high voltage.

Key specifications

• Current rating: 20 A
• Poles: 3 (three‑phase protection)
• Voltage rating: 480 V
• Part number: FAZ-B20/3
• Brand: Eaton

Why this breaker stands out

• Three-pole protection for 480 V networks: Specifically suited for three‑phase distribution, ensuring synchronized interruption across all phases to prevent phase-to-phase faults.
• Reliable Eaton engineering: Built to meet standard Eaton panel and accessory ecosystems, providing consistent performance within established electrical architectures.
• Clear, immediate fault response: Designed to quickly interrupt fault currents, helping minimize equipment damage and unplanned downtime in demanding environments.

Practical use cases

Ideal for facilities with 480 V three‑phase distribution, such as manufacturing floors, large HVAC and chiller systems, and industrial controls cabinets. Use the FAZ-B20/3 to guard motors, drives, and other high‑load equipment, ensuring that a short in one phase doesn’t cascade into broader system outages.

Who benefits most

• Facilities operating 480 V three‑phase systems needing dependable overcurrent protection
• Electrical panels and distribution boards that rely on Eaton components for compatibility and streamlined maintenance
• Maintenance teams seeking a straightforward, durable solution for spare parts and replacements in industrial environments

Practical guidance for deployment

• Match the breaker’s 20 A rating to the load demand of the protected circuit to ensure appropriate protection without nuisance tripping.
• Install within compatible Eaton panel assemblies designed to accommodate FAZ‑series devices for reliable performance and easy maintenance.
• Use as part of a broader 480 V safety strategy, pairing with proper grounding, enclosure protection, and lockout/tagout procedures.
