Eaton FAZ-C4/1-RT-SP Circuit Breaker, 4A, 1-Pole, 277V

The Eaton FAZ-C4/1-RT-SP Circuit Breaker, a 4 A, 1-pole unit designed for 277V AC, is built to meet the demanding needs of industrial electrical service, maintenance, and replacement projects. As part of the RT-series family, this breaker is engineered for dependable protection in commercial and light industrial environments where single‑phase circuits require precise overcurrent control.

• Exact-fit reliability for Eaton RT-series panels. Verify compatibility by matching the part number FAZ-C4/1-RT-SP to your installation requirements and panel documentation.
• Single-pole protection tailored for 277V circuits commonly used in lighting feeders, control circuits, and small-load branches in larger facilities.
• 4 A rating provides targeted overcurrent protection for circuits that don’t demand high current, helping minimize nuisance trips while safeguarding equipment.
• Industrial-grade design with the rugged engineering Eaton is known for, optimized for frequent maintenance cycles, quick replacements, and long service life in harsh environments.

Use cases you’ll encounter with this breaker include protecting a 277V lighting distribution run in a warehouse, safeguarding a control circuit for HVAC and fans, or serving as a reliable replacement component in an RT-series panel during scheduled maintenance. Its 1-pole configuration makes it ideal for dedicated circuits where single‑phase protection is sufficient, while maintaining compatibility with existing RT-series infrastructure.

How to approach compatibility and installation with confidence:

• Confirm fit by part number and ensure the RT-series panel and bus arrangement align with the FAZ-C4/1-RT-SP specifications.
• Match voltage and load requirements to 277V AC and a 4 A continuous load rating to prevent overloading protected circuits.
• Follow safety and code guidelines during replacement, including de-energizing the panel and observing manufacturer instructions for RT-series components.

Why choose this specific Eaton breaker over a generic option? The FAZ-C4/1-RT-SP is purpose-built to integrate with Eaton RT-series panels, ensuring a secure fit, consistent electrical characteristics, and predictable performance within an industrial electrical system. By sticking to the part number and series, you reduce compatibility guesswork and streamline maintenance or retrofit projects.
