Square D | FAP34050 | Circuit Breaker | 50A | 3-Pole | 480V

Meet the Square D FAP34050 Circuit Breaker — a 50A, 3-pole device designed to protect 480V three-phase circuits in demanding industrial environments. Engineered for maintenance, retrofit, and replacement projects, this breaker delivers reliable fault protection when you need it most.

Distinctive value points:

• Exact compatibility with Square D panel systems that support 3-pole, 480V configurations
• Three-pole design provides balanced protection across all three phases, helping prevent uneven loading and equipment damage
• 50A rating handles motor feeders and mid-range loads common in manufacturing, processing, and commercial HVAC applications
• 480V operation suits high-voltage equipment and industrial drives in many facilities
• Part number FAP34050 as your best reference for matching equipment and replacements, minimizing guesswork during retrofits

Important notes:

• Confirm fit and ratings before ordering. Use the part number FAP34050 as the primary compatibility reference to avoid mismatches in panel boards, bus bars, or MCCs.

Specifications

• Amperage: 50A
• Poles: 3-pole
• Voltage: 480V

What problems does this solve?

When maintaining or upgrading a facility’s electrical infrastructure, you need a breaker that matches the exact protection profile of your existing system. The FAP34050 ensures consistent trip characteristics, reduces nuisance trips, and simplifies spares management by aligning with the Square D family you already trust.

Use cases

• Maintenance and service outages on 480V three-phase equipment
• Retrofit projects replacing aging or failed breakers in industrial control panels, motor control centers, or switchgear
• New installations requiring a precise 50A, 480V, 3-pole protective device within a Square D ecosystem

Tips for installation and longevity

To maximize reliability, ensure proper mounting, tight terminal connections, and adherence to electrical codes. If you’re unsure about fit, remember that the part number is your best reference for compatibility. Always follow the manufacturer’s installation instructions and consult your panel’s labeling to confirm trip settings and interrupting capacity before placing the device into service.
