Eaton FAZ-D0.5/2-NA 0.5A 2-Pole 480 V Circuit Breaker

Eaton FAZ-D0.5/2-NA is a compact, two-pole circuit breaker designed for 480 V electrical systems. With a precise 0.5 A rating, it provides targeted overcurrent protection for low-current loads while ensuring safe, simultaneous disconnection of both hot legs when faults occur. Built to integrate with Eaton’s FAZ family, this unit combines dependable protection with a space-efficient footprint for panel builders and technicians working in demanding environments.

Key specifications at a glance

• Current rating: 0.5 A
• Poles: 2
• Voltage rating: 480 V
• Part number: FAZ-D0.5/2-NA
• Brand: Eaton

Why this matters for your system

In 480 V installations, protecting small, sensitive control circuits and auxiliary loads requires a breaker that won’t nuisance-trip under normal operating fluctuations. The FAZ-D0.5/2-NA delivers selective protection for low-current applications, reducing downtime and extending component life. The two-pole design ensures both conductors are disconnected together, enhancing safety and fault clearing in high-voltage panels.

Ideal use cases

• Industrial control panels and automation cabinets that operate on 480 V and require precise protection for low-current control circuits
• feeder circuits feeding relays, sensors, and small actuators where tight current limits are important
• High-voltage distribution boards in manufacturing facilities needing compact, reliable two-pole protection

Practical considerations and tips

Before installation, verify compatibility with your panel and bus arrangement, and ensure the 0.5 A rating matches the protected load’s continuous operating current. For best results, pair this breaker with loads that have predictable startup and running currents to minimize nuisance trips. When stocking replacements, consider keeping a spare FAZ-D0.5/2-NA to minimize downtime in critical 480 V circuits, and document the part number for quick identification in service manuals.
