Eaton FAZ-D25/2 25A 2-Pole 277 V Circuit Breaker Potential Transformer

The Eaton FAZ-D25/2 is a purpose-built circuit breaker designed to protect 277 V electrical setups while integrating with sensing and protection schemes that use potential transformers. With a 25 A rating and a compact 2-pole design, this unit delivers reliable, coordinated protection for commercial and light industrial panels.

Key specifications

• Part Number: FAZ-D25/2
• Current rating: 25 A
• Poles: 2
• Voltage rating: 277 V

Why this breaker stands out

• Dual-pole protection ensures simultaneous disconnection of both conductors, enhancing safety and reducing arc risks in 277 V systems.
• 277 V compatibility makes it an ideal fit for commercial lighting, HVAC, and distribution circuits commonly found in offices, schools, and retail spaces.
• Potential transformer-ready design supports protection and metering schemes that rely on sensing devices, enabling accurate monitoring and safer fault analysis.
• Trusted Eaton reliability backed by decades of electrical protection experience, designed to fit Eaton panels and compatible distribution assemblies.

Ideal use cases

• Main feeders and branch circuits in commercial electrical panels serving lighting, outlets, and small motor loads.
• Control panels and distribution boards where protection must be paired with measurement equipment for fault detection and system monitoring.
• retrofit projects upgrading older panels to modern, two-pole protection that aligns with 277 V infrastructure.

Practical considerations

When selecting the FAZ-D25/2, ensure your application uses two-pole protection at a 277 V supply and that any protection or metering strategy leverages potential transformers for accurate data and safe disconnection. This unit is designed to integrate smoothly into Eaton-compatible systems, providing a straightforward replacement path for equivalent 25 A, 2-pole, 277 V breakers.

Installation and lifecycle tips

• Verify the part number FAZ-D25/2 matches your panel configuration before replacement.
• Follow local electrical codes and manufacturer guidelines during installation to ensure proper torque on lug terminals and secure mounting.
• Plan for typical panel maintenance intervals to confirm continued alignment with your protection and metering strategy.
