Eaton FAZ-D0.5/3-NA 0.5A 3-Pole 480 V Circuit Breaker

Protect sensitive 3-phase equipment in industrial environments with the Eaton FAZ-D0.5/3-NA 0.5 A, 3-Pole, 480 V Circuit Breaker. Designed to interrupt overcurrent conditions quickly and reliably, this unit helps keep motors, drives, and control panels safe from damage caused by faults on a 480 V three-phase network.

Key specifications

• Manufacturer: Eaton
• Model / Part Number: FAZ-D0.5/3-NA
• Current rating: 0.5 A
• Poles: 3
• Voltage rating: 480 V
• Type: Circuit breaker for 3-phase protection

Use cases and applications

• Overcurrent protection for 3-phase equipment fed from 480 V panels, including small motors and control circuits.
• Protection of 3-phase feeders in industrial control panels where precise, low-current protection is required to prevent nuisance trips while maintaining safety.
• Replacement or upgrade in Eaton FAZ installations to ensure continued compatibility and reliable protection with a 0.5 A trip setting.

Why this matters

Balanced protection across all three phases is essential for preventing phase imbalances that can stress motors and drives. The FAZ-D0.5/3-NA’s three-pole design ensures that a fault trips all phases together, reducing the risk of downstream equipment damage and unplanned downtime. Choose this breaker when your application demands strict current limiting at 0.5 A in a 480 V, three-phase system.

Installation and compatibility

Designed to integrate with compatible Eaton panels and three-pole bus arrangements, this breaker should be installed by a qualified electrician in accordance with local electrical codes. Verify panel compatibility and follow Eaton’s installation guidelines to ensure secure mounting and proper wiring of all three phases.

Practical considerations

• The 0.5 A rating targets sensitive control circuits and small feeders, helping reduce nuisance trips without compromising safety.
• Three-pole protection provides robust, synchronized disconnection in fault events, safeguarding connected equipment and supporting safe shutdown procedures.
• As an authentic Eaton component, the FAZ-D0.5/3-NA integrates seamlessly with existing Eaton distributions and spare-parts ecosystems, simplifying maintenance and replacements.
