Eaton FAZ-B3/3 3A 3-Pole 480 V Circuit Breaker

The Eaton FAZ-B3/3 3A 3-Pole 480 V Circuit Breaker is a precise, dependable protector designed for modern three‑phase electrical systems. Engineered to handle up to 480 V and three phases, this FAZ-B3/3 model delivers targeted protection for small, critical loads while integrating seamlessly into industrial control panels and commercial distribution boards. Built by Eaton, it’s a purpose‑built solution when you need reliable overcurrent protection without oversizing the disconnect for your circuit.

• Three-pole configuration provides balanced protection across all three phases in a single device, simplifying wiring and panel layout.
• 3 ampere rating offers precise protection for low‑current, three‑phase circuits and control loads, helping to prevent nuisance trips on sensitive equipment.
• 480 V voltage rating suits standard 3‑phase distribution in many industrial and commercial environments, keeping your equipment protected at the system level.
• Part number FAZ-B3/3 ensures exact compatibility with Eaton FAZ series panels and replacement components, reducing installation guesswork and downtime.
• Brand‑trusted performance from Eaton, a name known for dependable protection and consistent electrical performance in demanding environments.

Who this is for: engineers, electricians, and maintenance teams responsible for three‑phase electrical systems in manufacturing floors, data centers, commercial facilities, and control cabinets. If you’re protecting small three‑phase loads or sensitive control circuits in a 480 V network, this breaker offers a scoped protection profile that helps keep downtime to a minimum while protecting wiring and devices from overcurrent conditions.

Key benefits and practical value:

• Reliable protection in compact form — one device protects all three lines, reducing part count and simplifying wiring inside panels.
• Accurate protection for sensitive loads — the 3 A rating is ideal for low‑current drives, logic panels, sensors, and other control circuits that require careful current limiting.
• Design and installation simplicity — designed to slot into Eaton FAZ ecosystems, making upgrades, replacements, or panel refurbishments smoother and faster.
• Clear identification and compatibility — the FAZ‑B3/3 designation clearly communicates its role and ensures you’re selecting the exact component for your 480 V, three‑phase setup.

How it compares to alternatives within a typical installation scenario: if your load requires higher or lower protection, you choose a different ampere rating within the FAZ family to match the circuit’s needs. The FAZ‑B3/3’s 3 A rating is particularly suited for light three‑phase control circuits or specialized equipment where aggressive protection could cause unnecessary interruptions, while still delivering robust protection against overcurrent events. This specificity helps you avoid over‑tripping, keeps production lines running, and reduces wear on motors and feeders compared with generic, higher‑rating breakers in the same space.

Practical setup tips to maximize value:

• Verify that your system voltage and panel are compatible with a 480 V, 3‑pole solution before installation. Compatibility with the FAZ line ensures reliable performance and easier maintenance.
• Label the circuit clearly in the panel to reflect the FAZ‑B3/3’s three‑phase protection, aiding future troubleshooting and audits.
• Keep a spare FAZ‑B3/3 on hand as part of a standard maintenance kit for quick replacement in critical control panels.
• Consult your facility’s electrical code and safety guidelines to ensure proper integration with existing protection schemes and coordination with upstream and downstream protective devices.

In short, the Eaton FAZ-B3/3 3A 3-Pole 480 V Circuit Breaker delivers targeted, reliable protection for three‑phase systems where a modest current rating is the right fit. With exact compatibility to Eaton’s FAZ platform, it simplifies installation, reduces downtime, and provides the dependable performance you expect from a trusted protection solution in industrial and commercial electrical environments.
