Eaton FAZ-D25/3-NA 25A 3-Pole 277 V Circuit Breaker

Eaton FAZ-D25/3-NA is a 25-amp, 3-pole circuit breaker designed for dependable protection in commercial electrical distributions. This FAZ-series unit (part number FAZ-D25/3-NA) interrupts power across all three phases to safeguard wiring, devices, and occupants from overloads and faults in 277 V systems.

• Three-pole protection delivers synchronized interrupting across all three hot conductors, ideal for 3-phase circuits common in commercial environments.
• 25 A rating provides appropriate protection for typical lighting grids, small motors, and other 277 V loads without nuisance trips.
• 277 V operating voltage tailored for line-to-neutral 277 V distribution found in many commercial buildings, offices, and facilities.
• Seamless Eaton compatibility designed to integrate with Eaton panelboards and the FAZ family, facilitating straightforward replacement and maintenance.
• Reliable protection engineered to respond to overloads and faults, helping minimize electrical damage and downtime.

Who it's for: facility managers, electrical contractors, and technicians maintaining commercial spaces with 277 V three-phase distribution. If you’re upgrading an aging or failed breaker in a panel that accepts FAZ-D series devices, the FAZ-D25/3-NA offers a precise, compatible solution.

Use cases and practical scenarios

• Protect 3-phase lighting systems and small motor loads in offices, retail centers, or warehouses powered by 277 V supplies.
• Replace a worn or failed 3-pole 25 A breaker in Eaton-compatible panelboards to restore reliable protection without rewiring.
• Prepare for future upfits—when expanding a facility’s 3-phase distribution, the FAZ-D25/3-NA provides a scalable protection option within the FAZ family.
