Eaton FAZ-D2/1-NA-SP 2A 1-Pole 277 V Circuit Breaker

The Eaton FAZ-D2/1-NA-SP is a compact, reliable protection device designed for 277 V electrical environments. As a 1-pole, 2 A circuit breaker, it delivers focused overload protection for a single branch circuit within commercial panels that support the FAZ series. Built to meet the demands of everyday electrical workloads, this part helps maintain safe, consistent operation of lighting and control circuits in busy spaces.

Key specifications

• Current rating: 2 A
• Poles: 1
• Voltage rating: 277 V
• Part number: FAZ-D2/1-NA-SP

Why this breaker stands out

Unlike generic substitutes, this Eaton FAZ-D2/1-NA-SP is purpose-built for FAZ-series panels, ensuring compatibility and predictable trip behavior in 277 V distribution environments. Its single-pole design targets a single circuit with precision, helping to prevent nuisance trips while safeguarding connected equipment and wiring from overloads.

Ideal use cases

• 277 V commercial lighting circuits in offices, retail spaces, and schools
• Small control circuits and auxiliary power feeds within industrial or facilities equipment
• Maintenance or upgrade projects where exact FAZ-series replacement parts are required

Practical benefits and outcomes

• Maintains circuit integrity by interrupting overloads on a dedicated branch
• Supports reliable operation of sensitive loads (lighting, signage, control gear) in 277 V systems
• Simple integration with existing Eaton panels that accept FAZ devices, reducing installation time
• Clear part identity (FAZ-D2/1-NA-SP) facilitates future replacements and stock management

Installation and compatibility tips

Before installation, confirm your panel accepts FAZ-series breakers and that the circuit truly operates at 277 V. Use the exact FAZ-D2/1-NA-SP part for a like-for-like replacement to preserve UL/NEC-compliant protection. Keep a spare on hand for maintenance to minimize downtime in critical lighting or control circuits.
