Eaton FAZ-D7/3-NA 7A 3-Pole 277 V Circuit Breaker

The Eaton FAZ-D7/3-NA 7A 3-Pole 277 V Circuit Breaker is a precise, reliable protective device built for three-phase power distribution in commercial and light-industrial environments. With a 7-amp rating and a 277-volt specification, it delivers predictable tripping behavior to safeguard equipment and keep critical systems up and running.

Designed for exact compatibility, this FAZ-D7/3-NA model is the ideal replacement or expansion choice for Eaton FAZ-series panels. Its three-pole design protects all three hot conductors in a 3-phase circuit, improving fault isolation and system safety in dense electrical layouts common in offices, data centers, and manufacturing spaces.

• Exact part identification: FAZ-D7/3-NA ensures proper fit and reliable performance within Eaton panel boards designed for the FAZ family.
• Three-pole protection: Covers all three phases in 3-phase networks, simplifying wiring and trip coordination across the circuit.
• 7-amp rating: Balanced protection for low-to-moderate load applications, reducing nuisance trips on lighting controls and small equipment while still guarding against overloads.
• 277 V operation: Suited for commercial power distribution and building automation systems that run on 277-volt three-phase power.
• Trusted brand: Eaton’s engineering offers consistent, dependable performance in demanding environments.

Use cases and scenarios:

• Protect three-phase lighting, control circuits, and small motors in commercial buildings and data centers.
• Install or replace within existing Eaton FAZ panels to maintain coordinated protection across all hot legs.
• Integrate into equipment rooms and panel boards where space, reliability, and quick maintenance are priorities.

Why this model stands out:

• Exact compatibility with Eaton FAZ-series panels reduces installation guesswork and ensures consistent trip performance.
• 3-pole configuration simplifies wiring and improves safety by ensuring simultaneous interruption on all phases during faults.
• The 7 A rating is purpose-built for common low-to-moderate load scenarios, helping minimize downtime from nuisance trips while protecting critical equipment.

Practical tips for best results:

• Confirm that your panel supports FAZ-D7/3-NA and that the system operates on 277V three-phase power before installation.
• Keep a spare FAZ-D7/3-NA on hand for quick maintenance, reducing system downtime in mission-critical setups.
• Pair with properly rated feeders and overcurrent protection to maintain overall system protection and code compliance.
