Eaton FAZ-B5/1-NA 5A, 1-Pole Circuit Breaker for 277V
Protect critical 277-volt circuits with precision using the Eaton FAZ-B5/1-NA circuit breaker. Designed for maintenance, retrofit, and replacement projects where exact specifications are essential, this unit delivers dependable single-pole overcurrent protection in a compact 5-amp package.
- Amperage: 5A
- Poles: 1-Pole
- Voltage: 277V
- Part Number: FAZ-B5/1-NA
- Best reference for compatibility: The part number FAZ-B5/1-NA is the most reliable identifier—always confirm fit and ratings on your equipment before ordering.
Why this exact FAZ-B5/1-NA matters
In electrical assemblies, a direct-fit breaker preserves panel labeling, trip characteristics, and overall system reliability. The FAZ-B5/1-NA is specifically suited for 277V circuits and single-pole configurations, making it an ideal choice for lighting runs, auxiliary power feeds, or other 277V applications that require precise amperage control without adding unnecessary bulk.
Ideal use cases
- Maintenance: replace a failed 5A, 1-pole breaker in existing 277V panels without altering other components.
- Retrofit: upgrade legacy circuits to a modern, compatible FAZ series breaker that matches original ratings.
- Replacement: substitute a worn or incompatible unit with a part-number-specific option to maintain panel integrity.
How to verify compatibility
Before ordering, compare your panel’s labeling and the device’s specifications to ensure a seamless fit. Rely on the FAZ-B5/1-NA part number as the primary compatibility reference, and verify that the circuit’s voltage and amperage requirements align with 277V, 5A, and 1-pole configuration.
Practical insights
Using the exact FAZ-B5/1-NA helps maintain consistent electrical protection and reduces the risk of incompatibility that can occur with generic substitutes. Keep a copy of the matching part number on hand for future maintenance and ordering to streamline replacements and keep your electrical system operating smoothly.
