Power protection for 480V three‑phase systems comes in a compact, reliable package with the Square D FA340501021 circuit breaker. This 50A, 3‑pole unit is designed for maintenance, retrofit, and replacement projects where exact specifications matter and downtime is costly.
Key specifications
- Amperage: 50 A

Why this matters
In industrial environments, protecting motors, feeders, and distribution circuits at the correct rating is critical. This FA340501021 unit ensures consistent interruption behavior and aligns with existing Square D panels that accept this part reference. Note that compatibility depends on your panel's design and listing—confirm fit and ratings before ordering. The FA340501021 part number is the best reference for ensuring correct replacement or retrofit.
Ideal use cases
- Maintenance: replace a failed or worn breaker in a 480V, 3-phase panel to restore steady protection.
- Retrofit: upgrade or refresh an electrical system that requires 50A, 3-pole coverage for 480V service.
- Replacement: match an aging installation that originally used FA340501021 for uninterrupted compatibility.
Practical tips for success
- Keep the FA340501021 part number handy as the primary reference for compatibility checks.
- Before purchasing, verify that your panel accepts 50A, 3-pole, 480V breakers and that the ratings align with your system requirements.
