Eaton FAZ-B5/3-NA 5A 3-Pole 480 V Circuit Breaker

Meet the Eaton FAZ-B5/3-NA 5A 3-Pole 480 V Circuit Breaker—a precise, dependable solution for protecting three-phase electrical circuits. In North American installations, this 480 V breaker delivers reliable overcurrent protection with a compact footprint, making it a practical choice for control panels, switchgear, and distributed power setups.

• Three-pole protection ensures simultaneous disconnection of all three phases in a 3‑phase circuit, preserving system balance and reducing the risk of phase faults.
• 5 A operating rating is ideal for safeguarding low-current loads, such as control circuitry, small motors, and automation equipment, while minimizing nuisance trips during startup transients.
• 480 V compatibility aligns with common industrial and commercial three-phase networks, helping you protect equipment without compromising performance.
• North America variant (NA) is designed to integrate smoothly with typical North American panel standards and wiring practices for straightforward installation.

Why this model stands out

Unlike generic solutions, the Eaton FAZ-B5/3-NA is purpose-built for reliable three-phase protection at 480 V, offering consistent trip behavior across all poles and a predictable response to overcurrent events. This translates to safer operation of downstream equipment and clearer fault diagnosis for maintenance teams.

Ideal use cases

• Small to mid-size three-phase motors and drives in manufacturing or processing facilities
• Automation panels, control cabinets, and equipment enclosures where precise protection of low-current circuits is essential
• Electrical distribution nodes in commercial spaces that run on 480 V three-phase services

Installation and compatibility tips

Install the FAZ-B5/3-NA in suitable panel environments that support 3-pole, 480 V devices. Always follow the manufacturer’s installation instructions and local electrical codes. Ensure secure mounting, correct wiring of all three poles, and proper termination practices to maintain reliable protection and ease of future maintenance.
