Schneider Electric FJA240504 Circuit Breaker — 50A, 2-Pole, 277V

The Schneider Electric FJA240504 is a purpose-built overcurrent protection device engineered for commercial and industrial electrical systems. With a 50-amp rating and a 2-pole design, it provides synchronized interruption of both lines in a 277-volt distribution circuit, helping to safeguard equipment and maintain safe operation in demanding environments.

Key Benefits and Features

• Precise electrical protection: 2-pole construction ensures both live conductors trip together, preventing unbalanced loads and reducing the risk of arc faults.
• High-current capability: 50A rating supports heavy-duty circuits such as motors, feeders, and lighting distributions commonly found in commercial facilities.
• 277V compatibility: Specifically designed for 277V systems used in many offices, warehouses, and retail locations, delivering reliable performance where this voltage is standard.
• Brand reliability: From Schneider Electric, a name trusted for consistent electrical protection and long-term compatibility with Schneider panels and accessories.
• Exact-fit guidance: The part number FJA240504 is the best reference for compatibility, making maintenance, retrofit, and replacement projects more predictable.

Ideal Use Scenarios

Use this circuit breaker for projects where you need robust protection for 277V circuits without compromising on speed of response or coordination with existing protection schemes. It’s well-suited for:

• Panel upgrades or retrofits in commercial buildings where 277V distribution is standard.
• Replacement of failed breakers in aging systems that require precise amperage and pole configuration.
• Maintenance outages or capacity expansions where maintaining exact specs minimizes panel rewiring and compatibility concerns.

Compatibility and Ordering Tips

• Verify fit and ratings before ordering: Ensure your panel accepts a 50A, 2-pole, 277V breaker's footprint and connection type.
• Reference the part number: Use FJA240504 as the primary compatibility reference to avoid mismatches during ordering or stocking.
• Context for best results: This unit is intended for environments where matching Schneider Electric specifications is essential for reliable protection and easy maintenance.

Practical Considerations

When integrating the FJA240504 into your electrical system, align its protection strategy with the overall panel design and upstream protection. Regular inspections of breakers and associated wiring help ensure consistent performance and safety across the distribution network.
