• Part number: FCP34050

Why this circuit breaker stands out

Designed by Square D, this FCP34050 unit aligns with common industrial panel configurations that require exact specifications for reliability and safety. Its 65kA short-circuit rating means it’s prepared to interrupt high-energy faults cleanly, reducing the risk of downstream damage and downtime. The 50A/3-pole/480V combination makes it an ideal fit for distribution panels and motor-start circuits where multi-phase protection is essential, while maintaining compatibility with retrofit and replacement projects that demand precise matching specs.

Ideal use cases

• Retrofit projects where existing equipment requires the exact FCP34050 specifications for seamless panel integration
• Maintenance replacements in 480V systems that rely on a 3-pole, 50A protection scheme
• Industrial feeders and motor control circuits that demand reliable short-circuit interruption up to 65kA
• New installations in panels designed to accept Square D breakers with matching part numbers and ratings

Compatibility and installation tips

Before ordering, confirm that the fit and ratings match your panel requirements. The part number FCP34050 is the best reference for compatibility, so verify it against your service panel’s documentation. Handle the breaker with dry hands and store it in its original packaging until installation to preserve performance. If your replacement needs require exact 3-pole, 480V, 50A protection with high interrupting capacity, this unit is designed to deliver consistent, reliable operation.

Practical benefits you’ll notice

• Clear alignment with standard 480V distribution schemes, simplifying retrofits and spare-part inventories
• Strong fault-handling capabilities reduce the risk of cascading failures across downstream equipment
• Consistent performance in commercial or light industrial environments where uptime matters
