Eaton FAZ-D40/3-NA 40A 3-Pole 240 V Circuit Breaker

Meet the Eaton FAZ-D40/3-NA, a purpose-built three-pole circuit breaker rated for 40 A at 240 V. This unit delivers reliable overcurrent protection for three-phase electrical systems, helping prevent damage to wiring, components, and downstream equipment while keeping critical lines powered when everything is running smoothly.

• Three-pole, 40 A, 240 V configuration designed for balanced protection across all phases in commercial and light-industrial panels.
• Part number FAZ-D40/3-NA ensures precise compatibility with Eaton FAZ-series breakers and panels that accept this line.
• Targeted overcurrent protection interrupts fault currents quickly to minimize wiring insulation stress and equipment wear.
• Stable, durable construction built for everyday operation in demanding environments where reliability matters most.

This breaker is ideal for protecting three-phase loads such as motors, pumps, conveyors, fans, and other equipment found in manufacturing floors, commercial facilities, and processing lines. By maintaining balanced phase protection, it helps avoid uneven loading that can lead to premature motor failure or drive issues.

Key benefits include reducing downtime from electrical faults, preventing damage from short circuits, and simplifying panel upgrades by aligning with Eaton’s FAZ family. Its 40 A rating hits a practical middle ground for mid-size equipment, providing solid protection without unnecessary nuisance trips in typical operating scenarios.

Use cases involve new installations and mid-life panel upgrades where three-phase protection is essential. It’s well-suited for control panels, motor control centers, HVAC distributions, and other three-phase circuits where dependable interrupt capability at 240 V is required.

Quick compatibility notes—verify that your enclosure or panel accepts FAZ-series breakers and that the FAZ-D40/3-NA matches your three-phase, 240 V distribution needs. When you install this unit, you’re choosing a proven Eaton design crafted to protect circuits and support steady, safe operation of your electrical system.
