Eaton FAZ-Z20/3 20A 3-Pole 277 V Circuit Breaker

Eaton FAZ-Z20/3 20A 3-Pole 277 V Circuit Breaker is a purpose-built protector for three‑phase 277‑volt circuits. With a 20‑amp rating and three poles, it delivers coordinated disconnection across all phases, helping prevent equipment damage and electrical hazards in commercial and industrial environments.

Designed for 277V three‑phase systems

This breaker is tailored for 277V distributions, where three‑phase circuits power lighting, motors, and control gear. The 3‑pole configuration ensures all phases trip together, reducing the risk of phase imbalance and simplifying safe maintenance in busy electrical rooms and utility spaces.

Key features that set it apart

• Three-pole, 20A protection precisely limits current on each phase of a 277V circuit, guarding against overloads without unnecessary trips on harmless surges.
• Coordinated trip across all phases minimizes arc exposure and ensures a safe, complete disconnection when protection is needed.
• Designed for Eaton FAZ‑Z family integration streamlined replacement and consistent performance across compatible Eaton panels and systems.
• Optimal for commercial and light industrial use ideal for lighting circuits, HVAC control, and small to mid‑sized motor control networks in offices, retail centers, warehouses, and workshops.

Use cases and practical applications

• 277V lighting infrastructure in large commercial spaces where uninterrupted service is critical and rapid fault isolation is required.
• Three‑phase motor control circuits for fans, pumps, conveyors, or processing equipment in warehouses and manufacturing environments.
• Control panels and distribution boards in offices or industrial settings that rely on standardized 277V three‑phase distribution.

Installation and compatibility notes

Ensure your electrical panel accepts FAZ‑Z series breakers and is configured for 277V three‑phase operation. This breaker is intended to be installed in compatible Eaton panels that support three‑pole devices of the FAZ‑Z line, providing a reliable, modular protection solution for maintained systems. Always follow local electrical codes, manufacturer guidelines, and proper de‑energization procedures during installation and maintenance.

Why choose the Eaton FAZ-Z20/3

If you’re standardizing on Eaton components for consistency, serviceability, and long‑term reliability, the FAZ‑Z20/3 offers precise 20A protection across all three phases in 277V systems. Its integration with the FAZ‑Z ecosystem simplifies spare parts planning, stocking, and future upgrades, helping you maintain a safer, more efficient electrical distribution network without overhauling existing panel infrastructure.
