Eaton FAZ-B5-2 - 5 A, 480 V, 2-Pole Circuit Breaker | AmpState

Eaton FAZ-B5-2 is a 5A, 480V, 2-pole molded case circuit breaker engineered to safeguard branch circuits within panelboards and load centers. Its compact form factor and rugged construction are designed to maximize panel space while delivering reliable, long-term protection for 480V distributions.

The core advantage lies in the thermal-magnetic trip unit, which provides stable overload protection and fast short-circuit disconnection. This balance helps maintain electrical continuity for connected equipment and reduces the risk of nuisance trips caused by temperature swings or minor surges, delivering predictable performance in demanding environments.

Key advantages:

• Compact molded-case design optimizes panel layout and makes retrofits smoother in tight enclosures.
• 2-pole protection ensures both hot legs are disconnected in a 480V circuit, enhancing safety and fault clearance.
• 5A rating targets low-current branch circuits such as control, lighting feeders, and instrumentation lines, while still providing robust overcurrent and short-circuit protection.
• OEM panel compatibility is built to work with matching OEM loadcenters and panelboards, ensuring secure form-fit, consistent electrical connections, and dependable trip characteristics.
• Versatile application suitable for residential, commercial, and light-industrial settings where 480V distribution is used.

Practical use cases:

• Protecting a 480V control circuit or lighting feeder in a commercial space, reducing downtime if a fault occurs.
• Safeguarding power feeders to 480V equipment in light industrial applications, where reliable protection minimizes disruption to production.
• Retrofit scenarios in existing panels that require a compatible, easily replaceable 2-pole 480V solution.

Why choose the Eaton FAZ-B5-2 for your 480V system? It blends precise thermal-magnetic protection with a space-conscious design and OEM-friendly compatibility, delivering predictable performance while simplifying panel layout and future servicing. If your distribution design calls for dependable 2-pole protection at 480V with a compact footprint, the FAZ-B5-2 stands out as a thoughtful, compatible choice that aligns with Eaton’s protection strategy for panelboards and load centers.
