Eaton FAZ-B8/3 8A 3-Pole 480 V Circuit Breaker

The Eaton FAZ-B8/3 is a robust 3-pole circuit breaker engineered to protect 3-phase electrical systems up to 480 V. With an 8 A current rating, it provides precise overcurrent protection for small to mid-size loads, helping you prevent equipment damage and downtime while keeping your control panels streamlined and safe.

Key specifications at a glance

• Current rating: 8 A
• Poles: 3
• Voltage rating: 480 V
• Part number: FAZ-B8/3

Why this 3-pole design matters

For any three-phase system, the FAZ-B8/3 protects all three conductors simultaneously. This synchronized protection minimizes the risk of imbalanced faults and ensures quicker disconnection on a fault event, safeguarding motors, drives, and other three-phase equipment in industrial, commercial, or processing environments.

Ideal use cases

• Protection for small to moderate 3-phase equipment in distribution panels and motor control centers
• Protection in HVAC, processing lines, conveyors, pumps, and compact industrial machinery that operate on 480 VAC
• Panel reconfigurations or replacements where 8 A, 3-pole protection is appropriate

Practical advantages and considerations

Choosing the FAZ-B8/3 helps you align protection with your actual load while maintaining a compact footprint in your electrical assemblies. Its 480 V rating ensures compatibility with standard industrial power distribution networks, reducing the risk of undersized protection for three-phase circuits. The 8 A rating is well-suited for controlled or lower-amperage branches where precise interruption thresholds are critical.

How it fits into your system

• Easy integration into Eaton-compatible panels and distribution boards that support 3-pole breakers
• Clear part identification with FAZ-B8/3 for quick maintenance and part replacement
• Reliable overcurrent protection that helps minimize unexpected downtime and equipment wear

Who benefits most

Maintenance engineers, panel builders, and facilities teams who manage 3-phase equipment operating at or below 480 V will find the FAZ-B8/3 a precise, dependable choice for safeguarding circuits while keeping wiring organized and accessible.
