Moeller FAZ-G4A-1 - 4A, 380VAC, 1-Pole, Circuit Breaker

The Moeller FAZ-G4A-1 is a compact, dependable single-pole circuit breaker designed for precise protection in modern electrical enclosures. With a 4 A current rating and a 380 VAC maximum, this device delivers targeted overcurrent protection for individual circuits inside panelboards, switchboards, and control panels across industrial, commercial, and OEM environments.

Key benefits that matter in real-world applications

• Focused single-circuit protection: 4 A rating keeps sensitive control circuits safeguarded without triggering nearby feeders.
• High-voltage suitability: Up to 380 VAC aligns with common industrial distribution standards, supporting reliable performance in demanding installations.
• Space-efficient 1-Pole design: optimizes panel footprint while maintaining robust protection for essential circuits.
• Versatile deployment: Ideal for panelboards, switchboards, and control panels in machines, conveyors, HVAC, pumps, and automation systems.

Who benefits from the FAZ-G4A-1

Engineers, fabricators, and maintenance technicians building or upgrading equipment will value the FAZ-G4A-1 for its predictable protection characteristics and straightforward integration into existing Moeller or OEM electrical architectures. It’s especially well-suited for OEM equipment, distribution panels, and motor control centers where reliable, localized protection is crucial.

Practical impact and use cases

Use the FAZ-G4A-1 to isolate and protect individual control circuits without compromising the rest of the panel. It helps reduce nuisance trips on critical lines, simplifies fault isolation, and supports safer, faster maintenance. Its compatibility with standard 1-pole configurations makes it a practical choice for selective protection in mixed-voltage environments.

Installation tips and considerations

When integrating this breaker, confirm the circuit’s current needs align with the 4 A rating and that the enclosure supports a 1-pole unit. Label each breaker clearly to streamline future diagnostics, and ensure the panelboard or switchboard is designed to accommodate this configuration for optimal performance.
