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

Meet the Eaton FAZ-B5/3 — a compact, three-pole circuit breaker designed for demanding 480-volt industrial power systems. With a precise 5 A current rating, this FAZ-series device provides targeted overcurrent protection for dedicated feeders and control circuits, helping your equipment run smoothly and reliably.

Key specifications at a glance

• Part Number: FAZ-B5/3
• Current rating: 5 A
• Poles: 3
• Voltage rating: 480 V
• Type: Eaton circuit breaker from the FAZ family

Why this 3-pole design matters

• Three-pole construction ensures balanced protection across all phases in a 480V, three-phase system.
• The 5 A rating is ideal for protecting low-load feeders or control circuits without triggering nuisance trips during normal operation.
• Engineered for integration into standard Eaton panels and distribution setups, offering a seamless upgrade path or replacement option.

Ideal use scenarios

Designed for commercial and industrial environments where 480V three-phase power is standard, the FAZ-B5/3 is well-suited to protect: - 480V feeders and branch circuits in control panels and motor control centers - Distribution boards and panel boards within warehouses, manufacturing facilities, and data centers that rely on reliable overcurrent protection

Practical benefits and outcomes

• Improved equipment protection: Quick, reliable trip response helps minimize damage from overloads and short circuits.
• Inventory efficiency: A single FAZ-B5/3 part covers common 480V, 3-pole protection needs, simplifying stocking and maintenance.
• Clear protection alignment: The 5 A rating provides a precise match for circuits that require tighter current limiting in a 480V system.

Installation and safety considerations

Install in accordance with local electrical codes and manufacturer guidelines. Ensure the circuit breaker rating matches the connected load’s protection requirements, and secure all connections with the appropriate torque. Regularly inspect for signs of wear or overheating and replace any unit that trips outside normal operation.
