Eaton FAZ-D4/3-NA 4A 3-Pole 480 V Circuit Breaker

Meet the Eaton FAZ-D4/3-NA 4A 3-Pole 480 V Circuit Breaker — a purpose-built, industrial-grade protection device designed for three-phase power systems. With a 4-amp nominal rating and a 480-volt maximum, this breaker provides precise, reliable protection for smaller-load circuits and motor-control lines within commercial and light-industrial panels. Its 3-pole configuration ensures synchronized protection across all three phases, helping prevent phase imbalances and equipment damage in demanding environments.

• Three-pole protection: full shutdown across all three phases in a 480 V system, maintaining balanced power distribution and safeguarding connected equipment.
• 4 A current rating: tailored protection for low-to-mid-load circuits, control panels, and motor-control circuits without unnecessary trips.
• 480 V system compatibility: ideal for industrial settings where three-phase power governs machinery and controls.
• Part of the Eaton FAZ family: designed for seamless compatibility with Eaton panel systems and spare-part inventories.
• Product reference: FAZ-D4/3-NA ensures straightforward identification and replacement in maintenance workflows.
• Ideal applications: industrial control panels, machine enclosures, distribution boards, conveyors, CNC machines, HVAC units, and other three-phase equipment in warehouses and manufacturing facilities.

Why this breaker stands out: it’s purpose-built to integrate with Eaton panels, offering reliable, plug-and-protect performance for three-phase loads. The 3-pole design consolidates protection into a single device, simplifying installation and field service while maintaining precise current-limiting for sensitive control circuits and small motors. This makes it a smart choice for technicians stocking spare parts for maintenance-heavy environments.

Practical tips for use:

• Match the 4 A rating to the load profile of your control circuits and small motors to avoid nuisance trips while still protecting equipment.
• Confirm that your panel and wiring arrangement are compatible with a 3-pole 480 V device to ensure safe, code-compliant installation.
• Keep FAZ-D4/3-NA in your standard parts inventory for quick replacement in compatible Eaton installations, reducing downtime when service is needed.

Equip your electrical distribution with the Eaton FAZ-D4/3-NA 4A 3-Pole 480 V Circuit Breaker and experience dependable three-phase protection built to perform in demanding industrial environments.
