Eaton FAZ-B10-1N 10A 480V 1-Pole Circuit Breaker

Meet the Eaton FAZ-B10-1N — a dependable 10A, 480V, 1-pole molded case circuit breaker designed to guard your panelboards and load centers against overcurrent and short-circuit events. Built for real-world reliability, this breaker leverages Eaton’s thermal-magnetic trip unit to deliver stable, repeatable protection, so you can trust your circuits stay safe under changing electrical loads.

Smart protection in a compact package

The FAZ-B10-1N features a compact molded-case design that respects valuable panel space, making it easier to fit more protection into tight installations. Its 1-pole configuration is ideal for single-phase circuits, such as lighting runs, receptacle banks, or control circuits, in residential, commercial, and light industrial environments. The 480V rating expands its usefulness to panelboards and distribution feeders found in higher-voltage commercial and industrial settings.

Why this model stands out

• Compact molded-case design maximizes panel-space efficiency without sacrificing protection capabilities.
• Thermal-magnetic trip unit delivers stable, repeatable protection against both overloads and short circuits, reducing nuisance trips and improving system reliability.
• 10A rating provides dedicated protection for circuits with moderate loads—ideal for lighting, small equipment, and branch circuits in mixed-use facilities.
• 480V operation enables safe incorporation into commercial and light industrial panelboards and distribution panels.
• 1-pole design protects a single hot conductor, simplifying installation in single-phase applications.
• OEM compatibility ensures straightforward replacement or upgrade in Eaton-compatible panelboards and load centers.

Practical use cases

Use the FAZ-B10-1N when you need reliable branch-circuit protection in panelboards and load centers where space is at a premium. It’s well-suited for:

• Residential and light commercial lighting circuits
• Small equipment feeds in retail or office environments
• Control circuits and auxiliary loads in light industrial settings
• Panelboard upgrades or replacements that require a matching Eaton protection solution

Installation and compatibility guidance

Pair the FAZ-B10-1N with matching Eaton OEM load centers and panelboards designed for molded-case breakers to ensure optimal fit and performance. Follow standard electrical safety practices: disconnect power before installation, ensure proper seating on the bus and mounting rails, and consult your panel’s installation instructions for any torque or alignment specifics. This model is designed to integrate cleanly into systems that require a 10A, 480V, 1-pole protection device.
